ne, api_visibility will automatically be set to "private". time_limit: int | None default `= None` stream_every: float default `= 0.5` key: int | str | tuple[int | str, ...] | None default `= None` A unique key for this event listener to be used in @gr.render(). If set, this value identifies an event as identical across re-renders when the key is identical. validator: Callable | None default `= None` Optional validation function to run before the main function. If provided, this function will be executed first with queue=False, and only if it completes successfully will the main function be called. The validator receives the same inputs as the main function and should return a `gr.validate()` for each input value. [Controlling Layout](../../guides/controlling-layout/)

Parameters ▼ fn: Callable | None | Literal['decorator'] default `= "decorator"` the function to call when this event is triggered. Often a machine learning model's prediction function.

to one input component, and the function should return a single value or a tuple of values, with each element in the tuple corresponding to one output component. inputs: Component | BlockContext | list[Component | BlockContext] | Set[Component | BlockContext] | None default `= None` List of gradio.components to use as inputs. If the function takes no inputs, this should be an empty list. outputs: Component | BlockContext | list[Component | BlockContext] | Set[Component | BlockContext] | None default `= None` List of gradio.components to use as outputs. If the function returns no outputs, this should be an empty list. api_name: str | None default `= None` defines how the endpoint appears in the API docs. Can be a string or None. If set to a string, the endpoint will be exposed in the API docs with the given name. If None (default), the name of the function will be used as the API endpoint. api_description: str | None | Literal[False] default `= None` Description of the API endpoint. Can be a string, None, or False. If set to a string, the endpoint will be exposed in the API docs with the given description. If None, the function's docstring will be used as the API endpoint description. If False, then no description will be displayed in the API docs. scroll_to_output: bool default `= False` If True, will scroll to output component on completion show_progress: Literal['full', 'minimal', 'hidden'] default `= "full"` how to show the progress animation while event is running: "full" shows a spinner which covers the output component area as well as a runtime display in the upper right corner, "minimal" only shows the runtime display, "hidden" shows no progress animation at all show_progress_on: Component | list[Component] | None default `= None` Component or list of components to show the progress animation on. If None, will show the progress animat

at all show_progress_on: Component | list[Component] | None default `= None` Component or list of components to show the progress animation on. If None, will show the progress animation on all of the output components. queue: bool default `= True` If True, will place the request on the queue, if the queue has been enabled. If False, will not put this event on the queue, even if the queue has been enabled. If None, will use the queue setting of the gradio app. batch: bool default `= False` If True, then the function should process a batch of inputs, meaning that it should accept a list of input values for each parameter. The lists should be of equal length (and be up to length `max_batch_size`). The function is then *required* to return a tuple of lists (even if there is only 1 output component), with each list in the tuple corresponding to one output component. max_batch_size: int default `= 4` Maximum number of inputs to batch together if this is called from the queue (only relevant if batch=True) preprocess: bool default `= True` If False, will not run preprocessing of component data before running 'fn' (e.g. leaving it as a base64 string if this method is called with the `Image` component). postprocess: bool default `= True` If False, will not run postprocessing of component data before returning 'fn' output to the browser. cancels: dict[str, Any] | list[dict[str, Any]] | None default `= None` A list of other events to cancel when this listener is triggered. For example, setting cancels=[click_event] will cancel the click_event, where click_event is the return value of another components .click method. Functions that have not yet run (or generators that are iterating) will be cancelled, but functions that are currently running will be allowed to finish. trigger_mode: Literal['once', 'multiple', 'always_last'] | None defaul

ators that are iterating) will be cancelled, but functions that are currently running will be allowed to finish. trigger_mode: Literal['once', 'multiple', 'always_last'] | None default `= None` If "once" (default for all events except `.change()`) would not allow any submissions while an event is pending. If set to "multiple", unlimited submissions are allowed while pending, and "always_last" (default for `.change()` and `.key_up()` events) would allow a second submission after the pending event is complete. js: str | Literal[True] | None default `= None` Optional frontend js method to run before running 'fn'. Input arguments for js method are values of 'inputs' and 'outputs', return should be a list of values for output components. concurrency_limit: int | None | Literal['default'] default `= "default"` If set, this is the maximum number of this event that can be running simultaneously. Can be set to None to mean no concurrency_limit (any number of this event can be running simultaneously). Set to "default" to use the default concurrency limit (defined by the `default_concurrency_limit` parameter in `Blocks.queue()`, which itself is 1 by default). concurrency_id: str | None default `= None` If set, this is the id of the concurrency group. Events with the same concurrency_id will be limited by the lowest set concurrency_limit. api_visibility: Literal['public', 'private', 'undocumented'] default `= "public"` controls the visibility and accessibility of this endpoint. Can be "public" (shown in API docs and callable by clients), "private" (hidden from API docs and not callable by clients), or "undocumented" (hidden from API docs but callable by clients and via gr.load). If fn is None, api_visibility will automatically be set to "private". time_limit: int | None default `= None` stream_every: float default `= 0.5` key: int | str | t

api_visibility will automatically be set to "private". time_limit: int | None default `= None` stream_every: float default `= 0.5` key: int | str | tuple[int | str, ...] | None default `= None` A unique key for this event listener to be used in @gr.render(). If set, this value identifies an event as identical across re-renders when the key is identical. validator: Callable | None default `= None` Optional validation function to run before the main function. If provided, this function will be executed first with queue=False, and only if it completes successfully will the main function be called. The validator receives the same inputs as the main function and should return a `gr.validate()` for each input value.

If None, will show the progress animation on all of the output components. queue: bool default `= True` If True, will place the request on the queue, if the queue has been enabled. If False, will not put this event on the queue, even if the queue has been enabled. If None, will use the queue setting of the gradio app. batch: bool default `= False` If True, then the function should process a batch of inputs, meaning that it should accept a list of input values for each parameter. The lists should be of equal length (and be up to length `max_batch_size`). The function is then *required* to return a tuple of lists (even if there is only 1 output component), with each list in the tuple corresponding to one output component. max_batch_size: int default `= 4` Maximum number of inputs to batch together if this is called from the queue (only relevant if batch=True) preprocess: bool default `= True` If False, will not run preprocessing of component data before running 'fn' (e.g. leaving it as a base64 string if this method is called with the `Image` component). postprocess: bool default `= True` If False, will not run postprocessing of component data before returning 'fn' output to the browser. cancels: dict[str, Any] | list[dict[str, Any]] | None default `= None` A list of other events to cancel when this listener is triggered.

Parameters ▼ label: str default `= "Download"` Text to display on the button. Defaults to "Download". value: str | Path | Callable | None default `= None` A str or pathlib.Path filepath or URL to download, or a Callable that returns a str or pathlib.Path filepath or URL to download. every: Timer | float | None default `= None` Continously calls `value` to recalculate it if `value` is a function (has no effect otherwise). Can provide a Timer whose tick resets `value`, or a float that provides the regular interval for the reset Timer. inputs: Component | list[Component] | set[Component] | None default `= None` Components that are used as inputs to calculate `value` if `value` is a function (has no effect otherwise). `value` is recalculated any time the inputs change. variant: Literal['primary', 'secondary', 'stop'] default `= "secondary"` 'primary' for main call-to-action, 'secondary' for a more subdued style, 'stop' for a stop button. visible: bool | Literal['hidden'] default `= True` If False, component will be hidden. If "hidden", component will be visually hidden and not take up space in the layout but still exist in the DOM size: Literal['sm', 'md', 'lg'] default `= "lg"` size of the button. Can be "sm", "md", or "lg". icon: str | None default `= None` URL or path to the icon file to display within the button. If None, no icon will be displayed. scale: int | None default `= None` relative size compared to adjacent Components. For example if Components A and B are in a Row, and A has scale=2, and B has scale=1, A will be twice as wide as B. Should be an integer. scale applies in Rows, and to top-level Components in Blocks where fill_height=True. min_width: int | None default `= None` minimum pixel width, will wrap if not sufficient screen space to satisfy this value. If a certain scale v

If a certain scale value results in this Component being narrower than min_width, the min_width parameter will be respected first. interactive: bool default `= True` If False, the UploadButton will be in a disabled state. elem_id: str | None default `= None` An optional string that is assigned as the id of this component in the HTML DOM. Can be used for targeting CSS styles. elem_classes: list[str] | str | None default `= None` An optional list of strings that are assigned as the classes of this component in the HTML DOM. Can be used for targeting CSS styles. render: bool default `= True` If False, component will not render be rendered in the Blocks context. Should be used if the intention is to assign event listeners now but render the component later. key: int | str | tuple[int | str, ...] | None default `= None` in a gr.render, Components with the same key across re-renders are treated as the same component, not a new component. Properties set in 'preserved_by_key' are not reset across a re-render. preserved_by_key: list[str] | str | None default `= "value"` A list of parameters from this component's constructor. Inside a gr.render() function, if a component is re-rendered with the same key, these (and only these) parameters will be preserved in the UI (if they have been changed by the user or an event listener) instead of re-rendered based on the values provided during constructor.

Description Event listeners allow you to respond to user interactions with the UI components you've defined in a Gradio Blocks app. When a user interacts with an element, such as changing a slider value or uploading an image, a function is called. Supported Event Listeners The DownloadButton component supports the following event listeners. Each event listener takes the same parameters, which are listed in the Event Parameters table below. Listeners DownloadButton.click(fn, ···) Triggered when the DownloadButton is clicked. Event Parameters Parameters ▼ fn: Callable | None | Literal['decorator'] default `= "decorator"` the function to call when this event is triggered. Often a machine learning model's prediction function. Each parameter of the function corresponds to one input component, and the function should return a single value or a tuple of values, with each element in the tuple corresponding to one output component. inputs: Component | BlockContext | list[Component | BlockContext] | Set[Component | BlockContext] | None default `= None` List of gradio.components to use as inputs. If the function takes no inputs, this should be an empty list. outputs: Component | BlockContext | list[Component | BlockContext] | Set[Component | BlockContext] | None default `= None` List of gradio.components to use as outputs. If the function returns no outputs, this should be an empty list. api_name: str | None default `= None` defines how the endpoint appears in the API docs. Can be a string or None. If set to a string, the endpoint will be exposed in the API docs with the given name. If None (default), the name of the function will be used as the API endpoint. api_description: str | None | Literal[False] default `= None` Description of the API endpoint. Can be a string, None, or False. If set to a string, the endpoint will be exposed in the API docs wit

If False, then no description will be displayed in the API docs. scroll_to_output: bool default `= False` If True, will scroll to output component on completion show_progress: Literal['full', 'minimal', 'hidden'] default `= "full"` how to show the progress animation while event is running: "full" shows a spinner which covers the output component area as well as a runtime display in the upper right corner, "minimal" only shows the runtime display, "hidden" shows no progress animation at all show_progress_on: Component | list[Component] | None default `= None` Component or list of components to show the progress animation on. If None, will show the progress animation on all of the output components. queue: bool default `= True` If True, will place the request on the queue, if the queue has been enabled. If False, will not put this event on the queue, even if the queue has been enabled. If None, will use the queue setting of the gradio app. batch: bool default `= False` If True, then the function should process a batch of inputs, meaning that it should accept a list of input values for each parameter. The lists should be of equal length (and be up to length `max_batch_size`).

Blocks is Gradio's low-level API that allows you to create more custom web applications and demos than Interfaces (yet still entirely in Python). Compared to the Interface class, Blocks offers more flexibility and control over: (1) the layout of components (2) the events that trigger the execution of functions (3) data flows (e.g. inputs can trigger outputs, which can trigger the next level of outputs). Blocks also offers ways to group together related demos such as with tabs. The basic usage of Blocks is as follows: create a Blocks object, then use it as a context (with the "with" statement), and then define layouts, components, or events within the Blocks context. Finally, call the launch() method to launch the demo.

Parameters ▼ analytics_enabled: bool | None default `= None` Whether to allow basic telemetry. If None, will use GRADIO_ANALYTICS_ENABLED environment variable or default to True. mode: str default `= "blocks"` A human-friendly name for the kind of Blocks or Interface being created. Used internally for analytics. title: str | I18nData default `= "Gradio"` The tab title to display when this is opened in a browser window. fill_height: bool default `= False` Whether to vertically expand top-level child components to the height of the window. If True, expansion occurs when the scale value of the child components >= 1. fill_width: bool default `= False` Whether to horizontally expand to fill container fully. If False, centers and constrains app to a maximum width. Only applies if this is the outermost `Blocks` in your Gradio app. delete_cache: tuple[int, int] | None default `= None` A tuple corresponding [frequency, age] both expressed in number of seconds. Every `frequency` seconds, the temporary files created by this Blocks instance will be deleted if more than `age` seconds have passed since the file was created. For example, setting this to (86400, 86400) will delete temporary files every day. The cache will be deleted entirely when the server restarts. If None, no cache deletion will occur.

t `= False` If True, suppresses most print statements. footer_links: list[Literal['api', 'gradio', 'settings'] | dict[str, str]] | None default `= None` The links to display in the footer of the app. Accepts a list, where each element of the list must be one of "api", "gradio", or "settings" corresponding to the API docs, "built with Gradio", and settings pages respectively. If None, all three links will be shown in the footer. An empty list means that no footer is shown. allowed_paths: list[str] | None default `= None` List of complete filepaths or parent directories that gradio is allowed to serve. Must be absolute paths. Warning: if you provide directories, any files in these directories or their subdirectories are accessible to all users of your app. Can be set by comma separated environment variable GRADIO_ALLOWED_PATHS. These files are generally assumed to be secure and will be displayed in the browser when possible. blocked_paths: list[str] | None default `= None` List of complete filepaths or parent directories that gradio is not allowed to serve (i.e. users of your app are not allowed to access). Must be absolute paths. Warning: takes precedence over `allowed_paths` and all other directories exposed by Gradio by default. Can be set by comma separated environment variable GRADIO_BLOCKED_PATHS. root_path: str | None default `= None` The root path (or "mount point") of the application, if it's not served from the root ("/") of the domain. Often used when the application is behind a reverse proxy that forwards requests to the application. For example, if the application is served at "https://example.com/myapp", the `root_path` should be set to "/myapp". A full URL beginning with http:// or https:// can be provided, which will be used as the root path in its entirety. Can be set by environment variable GRADIO_ROOT_PATH. Defaults to "". app_kwargs: dict[str, Any] | None defa

ps:// can be provided, which will be used as the root path in its entirety. Can be set by environment variable GRADIO_ROOT_PATH. Defaults to "". app_kwargs: dict[str, Any] | None default `= None` Additional keyword arguments to pass to the underlying FastAPI app as a dictionary of parameter keys and argument values. For example, `{"docs_url": "/docs"}` state_session_capacity: int default `= 10000` The maximum number of sessions whose information to store in memory. If the number of sessions exceeds this number, the oldest sessions will be removed. Reduce capacity to reduce memory usage when using gradio.State or returning updated components from functions. Defaults to 10000. share_server_address: str | None default `= None` Use this to specify a custom FRP server and port for sharing Gradio apps (only applies if share=True). If not provided, will use the default FRP server at https://gradio.live. See https://github.com/huggingface/frp for more information. share_server_protocol: Literal['http', 'https'] | None default `= None` Use this to specify the protocol to use for the share links. Defaults to "https", unless a custom share_server_address is provided, in which case it defaults to "http". If you are using a custom share_server_address and want to use https, you must set this to "https". share_server_tls_certificate: str | None default `= None` The path to a TLS certificate file to use when connecting to a custom share server. This parameter is not used with the default FRP server at https://gradio.live. Otherwise, you must provide a valid TLS certificate file (e.g. a "cert.pem") relative to the current working directory, or the connection will not use TLS encryption, which is insecure. auth_dependency: Callable[[fastapi.Request], str | None] | None default `= None` A function that takes a FastAPI request and returns a string user ID or None. If the functio

nsecure. auth_dependency: Callable[[fastapi.Request], str | None] | None default `= None` A function that takes a FastAPI request and returns a string user ID or None. If the function returns None for a specific request, that user is not authorized to access the app (they will see a 401 Unauthorized response). To be used with external authentication systems like OAuth. Cannot be used with `auth`. max_file_size: str | int | None default `= None` The maximum file size in bytes that can be uploaded. Can be a string of the form "<value><unit>", where value is any positive integer and unit is one of "b", "kb", "mb", "gb", "tb". If None, no limit is set. enable_monitoring: bool | None default `= None` Enables traffic monitoring of the app through the /monitoring endpoint. By default is None, which enables this endpoint. If explicitly True, will also print the monitoring URL to the console. If False, will disable monitoring altogether. strict_cors: bool default `= True` If True, prevents external domains from making requests to a Gradio server running on localhost. If False, allows requests to localhost that originate from localhost but also, crucially, from "null". This parameter should normally be True to prevent CSRF attacks but may need to be False when embedding a *locally-running Gradio app* using web components. node_server_name: str | None default `= None` node_port: int | None default `= None` ssr_mode: bool | None default `= None` If True, the Gradio app will be rendered using server-side rendering mode, which is typically more performant and provides better SEO, but this requires Node 20+ to be installed on the system. If False, the app will be rendered using client-side rendering mode. If None, will use GRADIO_SSR_MODE environment variable or default to False. pwa: bool | None default `= None` If True, the Gradio app will

rendered using client-side rendering mode. If None, will use GRADIO_SSR_MODE environment variable or default to False. pwa: bool | None default `= None` If True, the Gradio app will be set up as an installable PWA (Progressive Web App). If set to None (default behavior), then the PWA feature will be enabled if this Gradio app is launched on Spaces, but not otherwise. mcp_server: bool | None default `= None` If True, the Gradio app will be set up as an MCP server and documented functions will be added as MCP tools. If None (default behavior), then the GRADIO_MCP_SERVER environment variable will be used to determine if the MCP server should be enabled. i18n: I18n | None default `= None` An I18n instance containing custom translations, which are used to translate strings in our components (e.g. the labels of components or Markdown strings). This feature can only be used to translate static text in the frontend, not values in the backend. theme: Theme | str | None default `= None` A Theme object or a string representing a theme. If a string, will look for a built-in theme with that name (e.g. "soft" or "default"), or will attempt to load a theme from the Hugging Face Hub (e.g. "gradio/monochrome"). If None, will use the Default theme. css: str | None default `= None` Custom css as a code string. This css will be included in the demo webpage. css_paths: str | Path | list[str | Path] | None default `= None` Custom css as a pathlib.Path to a css file or a list of such paths. This css files will be read, concatenated, and included in the demo webpage. If the `css` parameter is also set, the css from `css` will be included first. js: str | Literal[True] | None default `= None` Custom js as a code string. The js code will automatically be executed when the page loads. For more flexibility, use the head parameter to insert js inside <script> tags.

ction function. Each parameter of the function corresponds to one input component, and the function should return a single value or a tuple of values, with each element in the tuple corresponding to one output component. inputs: Component | BlockContext | list[Component | BlockContext] | Set[Component | BlockContext] | None default `= None` List of gradio.components to use as inputs. If the function takes no inputs, this should be an empty list. outputs: Component | BlockContext | list[Component | BlockContext] | Set[Component | BlockContext] | None default `= None` List of gradio.components to use as outputs. If the function returns no outputs, this should be an empty list. api_name: str | None default `= None` defines how the endpoint appears in the API docs. Can be a string or None. If set to a string, the endpoint will be exposed in the API docs with the given name. If None (default), the name of the function will be used as the API endpoint. api_description: str | None | Literal[False] default `= None` Description of the API endpoint. Can be a string, None, or False. If set to a string, the endpoint will be exposed in the API docs with the given description. If None, the function's docstring will be used as the API endpoint description. If False, then no description will be displayed in the API docs. scroll_to_output: bool default `= False` If True, will scroll to output component on completion show_progress: Literal['full', 'minimal', 'hidden'] default `= "full"` how to show the progress animation while event is running: "full" shows a spinner which covers the output component area as well as a runtime display in the upper right corner, "minimal" only shows the runtime display, "hidden" shows no progress animation at all show_progress_on: Component | list[Component] | None default `= None` Component or list of components to show the pro

the runtime display, "hidden" shows no progress animation at all show_progress_on: Component | list[Component] | None default `= None` Component or list of components to show the progress animation on. If None, will show the progress animation on all of the output components. queue: bool default `= True` If True, will place the request on the queue, if the queue has been enabled. If False, will not put this event on the queue, even if the queue has been enabled. If None, will use the queue setting of the gradio app. batch: bool default `= False` If True, then the function should process a batch of inputs, meaning that it should accept a list of input values for each parameter. The lists should be of equal length (and be up to length `max_batch_size`). The function is then *required* to return a tuple of lists (even if there is only 1 output component), with each list in the tuple corresponding to one output component. max_batch_size: int default `= 4` Maximum number of inputs to batch together if this is called from the queue (only relevant if batch=True) preprocess: bool default `= True` If False, will not run preprocessing of component data before running 'fn' (e.g. leaving it as a base64 string if this method is called with the `Image` component). postprocess: bool default `= True` If False, will not run postprocessing of component data before returning 'fn' output to the browser. cancels: dict[str, Any] | list[dict[str, Any]] | None default `= None` A list of other events to cancel when this listener is triggered. For example, setting cancels=[click_event] will cancel the click_event, where click_event is the return value of another components .click method. Functions that have not yet run (or generators that are iterating) will be cancelled, but functions that are currently running will be allowed to finish. trigger_mode:

s .click method. Functions that have not yet run (or generators that are iterating) will be cancelled, but functions that are currently running will be allowed to finish. trigger_mode: Literal['once', 'multiple', 'always_last'] | None default `= None` If "once" (default for all events except `.change()`) would not allow any submissions while an event is pending. If set to "multiple", unlimited submissions are allowed while pending, and "always_last" (default for `.change()` and `.key_up()` events) would allow a second submission after the pending event is complete. js: str | Literal[True] | None default `= None` Optional frontend js method to run before running 'fn'. Input arguments for js method are values of 'inputs' and 'outputs', return should be a list of values for output components. concurrency_limit: int | None | Literal['default'] default `= "default"` If set, this is the maximum number of this event that can be running simultaneously. Can be set to None to mean no concurrency_limit (any number of this event can be running simultaneously). Set to "default" to use the default concurrency limit (defined by the `default_concurrency_limit` parameter in `Blocks.queue()`, which itself is 1 by default). concurrency_id: str | None default `= None` If set, this is the id of the concurrency group. Events with the same concurrency_id will be limited by the lowest set concurrency_limit. api_visibility: Literal['public', 'private', 'undocumented'] default `= "public"` controls the visibility and accessibility of this endpoint. Can be "public" (shown in API docs and callable by clients), "private" (hidden from API docs and not callable by clients), or "undocumented" (hidden from API docs but callable by clients and via gr.load). If fn is None, api_visibility will automatically be set to "private". time_limit: int | None default `= None` stream_every:

If fn is None, api_visibility will automatically be set to "private". time_limit: int | None default `= None` stream_every: float default `= 0.5` key: int | str | tuple[int | str, ...] | None default `= None` A unique key for this event listener to be used in @gr.render(). If set, this value identifies an event as identical across re-renders when the key is identical. validator: Callable | None default `= None` Optional validation function to run before the main function. If provided, this function will be executed first with queue=False, and only if it completes successfully will the main function be called. The validator receives the same inputs as the main function and should return a `gr.validate()` for each input value.

If not provided, it is set to False by default every time, except when running in Google Colab. When localhost is not accessible (e.g. Google Colab), setting share=False is not supported. Can be set by environment variable GRADIO_SHARE=True. debug: bool default `= False` if True, blocks the main thread from running. If running in Google Colab, this is needed to print the errors in the cell output. max_threads: int default `= 40` the maximum number of total threads that the Gradio app can generate in parallel. The default is inherited from the starlette library (currently 40). auth: Callable[[str, str], bool] | tuple[str, str] | list[tuple[str, str]] | None default `= None` If provided, username and password (or list of username-password tuples) required to access app. Can also provide function that takes username and password and returns True if valid login. auth_message: str | None default `= None` If provided, HTML message provided on login page. prevent_thread_lock: bool default `= False` By default, the gradio app blocks the main thread while the server is running. If set to True, the gradio app will not block and the gradio server will terminate as soon as the script finishes. show_error: bool default `= False` If True, any errors in the gradio app will be displayed in an alert modal and printed in the browser console log. They will also be displayed in the alert modal of downstream apps

default `= False` If True, any errors in the gradio app will be displayed in an alert modal and printed in the browser console log. They will also be displayed in the alert modal of downstream apps that gr.load() this app. server_name: str | None default `= None` to make app accessible on local network, set this to "0.0.0.0". Can be set by environment variable GRADIO_SERVER_NAME. If None, will use "127.0.0.1". server_port: int | None default `= None` will start gradio app on this port (if available). Can be set by environment variable GRADIO_SERVER_PORT. If None, will search for an available port starting at 7860. height: int default `= 500` The height in pixels of the iframe element containing the gradio app (used if inline=True) width: int | str default `= "100%"` The width in pixels of the iframe element containing the gradio app (used if inline=True) favicon_path: str | Path | None default `= None` If a path to a file (.png, .gif, or .ico) is provided, it will be used as the favicon for the web page. ssl_keyfile: str | None default `= None` If a path to a file is provided, will use this as the private key file to create a local server running on https. ssl_certfile: str | None default `= None` If a path to a file is provided, will use this as the signed certificate for https. Needs to be provided if ssl_keyfile is provided. ssl_keyfile_password: str | None default `= None` If a password is provided, will use this with the ssl certificate for https. ssl_verify: bool default `= True` If False, skips certificate validation which allows self-signed certificates to be used. quiet: bool default `= False` If True, suppresses most print statements. footer_links: list[Literal['api', 'gradio', 'settings'] | dict[str, str]] | None default `= None` The links to display in the

t `= False` If True, suppresses most print statements. footer_links: list[Literal['api', 'gradio', 'settings'] | dict[str, str]] | None default `= None` The links to display in the footer of the app. Accepts a list, where each element of the list must be one of "api", "gradio", or "settings" corresponding to the API docs, "built with Gradio", and settings pages respectively. If None, all three links will be shown in the footer. An empty list means that no footer is shown. allowed_paths: list[str] | None default `= None` List of complete filepaths or parent directories that gradio is allowed to serve. Must be absolute paths. Warning: if you provide directories, any files in these directories or their subdirectories are accessible to all users of your app. Can be set by comma separated environment variable GRADIO_ALLOWED_PATHS. These files are generally assumed to be secure and will be displayed in the browser when possible. blocked_paths: list[str] | None default `= None` List of complete filepaths or parent directories that gradio is not allowed to serve (i.e. users of your app are not allowed to access). Must be absolute paths. Warning: takes precedence over `allowed_paths` and all other directories exposed by Gradio by default. Can be set by comma separated environment variable GRADIO_BLOCKED_PATHS. root_path: str | None default `= None` The root path (or "mount point") of the application, if it's not served from the root ("/") of the domain. Often used when the application is behind a reverse proxy that forwards requests to the application. For example, if the application is served at "https://example.com/myapp", the `root_path` should be set to "/myapp". A full URL beginning with http:// or https:// can be provided, which will be used as the root path in its entirety. Can be set by environment variable GRADIO_ROOT_PATH. Defaults to "". app_kwargs: dict[str, Any] | None defa

ps:// can be provided, which will be used as the root path in its entirety. Can be set by environment variable GRADIO_ROOT_PATH. Defaults to "". app_kwargs: dict[str, Any] | None default `= None` Additional keyword arguments to pass to the underlying FastAPI app as a dictionary of parameter keys and argument values. For example, `{"docs_url": "/docs"}` state_session_capacity: int default `= 10000` The maximum number of sessions whose information to store in memory. If the number of sessions exceeds this number, the oldest sessions will be removed. Reduce capacity to reduce memory usage when using gradio.State or returning updated components from functions. Defaults to 10000. share_server_address: str | None default `= None` Use this to specify a custom FRP server and port for sharing Gradio apps (only applies if share=True). If not provided, will use the default FRP server at https://gradio.live. See https://github.com/huggingface/frp for more information. share_server_protocol: Literal['http', 'https'] | None default `= None` Use this to specify the protocol to use for the share links. Defaults to "https", unless a custom share_server_address is provided, in which case it defaults to "http". If you are using a custom share_server_address and want to use https, you must set this to "https". share_server_tls_certificate: str | None default `= None` The path to a TLS certificate file to use when connecting to a custom share server. This parameter is not used with the default FRP server at https://gradio.live. Otherwise, you must provide a valid TLS certificate file (e.g. a "cert.pem") relative to the current working directory, or the connection will not use TLS encryption, which is insecure. auth_dependency: Callable[[fastapi.Request], str | None] | None default `= None` A function that takes a FastAPI request and returns a string user ID or None. If the functio

nsecure. auth_dependency: Callable[[fastapi.Request], str | None] | None default `= None` A function that takes a FastAPI request and returns a string user ID or None. If the function returns None for a specific request, that user is not authorized to access the app (they will see a 401 Unauthorized response). To be used with external authentication systems like OAuth. Cannot be used with `auth`. max_file_size: str | int | None default `= None` The maximum file size in bytes that can be uploaded. Can be a string of the form "<value><unit>", where value is any positive integer and unit is one of "b", "kb", "mb", "gb", "tb". If None, no limit is set. enable_monitoring: bool | None default `= None` Enables traffic monitoring of the app through the /monitoring endpoint. By default is None, which enables this endpoint. If explicitly True, will also print the monitoring URL to the console. If False, will disable monitoring altogether. strict_cors: bool default `= True` If True, prevents external domains from making requests to a Gradio server running on localhost. If False, allows requests to localhost that originate from localhost but also, crucially, from "null". This parameter should normally be True to prevent CSRF attacks but may need to be False when embedding a *locally-running Gradio app* using web components. node_server_name: str | None default `= None` node_port: int | None default `= None` ssr_mode: bool | None default `= None` If True, the Gradio app will be rendered using server-side rendering mode, which is typically more performant and provides better SEO, but this requires Node 20+ to be installed on the system. If False, the app will be rendered using client-side rendering mode. If None, will use GRADIO_SSR_MODE environment variable or default to False. pwa: bool | None default `= None` If True, the Gradio app will

rendered using client-side rendering mode. If None, will use GRADIO_SSR_MODE environment variable or default to False. pwa: bool | None default `= None` If True, the Gradio app will be set up as an installable PWA (Progressive Web App). If set to None (default behavior), then the PWA feature will be enabled if this Gradio app is launched on Spaces, but not otherwise. mcp_server: bool | None default `= None` If True, the Gradio app will be set up as an MCP server and documented functions will be added as MCP tools. If None (default behavior), then the GRADIO_MCP_SERVER environment variable will be used to determine if the MCP server should be enabled. i18n: I18n | None default `= None` An I18n instance containing custom translations, which are used to translate strings in our components (e.g. the labels of components or Markdown strings). This feature can only be used to translate static text in the frontend, not values in the backend. theme: Theme | str | None default `= None` A Theme object or a string representing a theme. If a string, will look for a built-in theme with that name (e.g. "soft" or "default"), or will attempt to load a theme from the Hugging Face Hub (e.g. "gradio/monochrome"). If None, will use the Default theme. css: str | None default `= None` Custom css as a code string. This css will be included in the demo webpage. css_paths: str | Path | list[str | Path] | None default `= None` Custom css as a pathlib.Path to a css file or a list of such paths. This css files will be read, concatenated, and included in the demo webpage. If the `css` parameter is also set, the css from `css` will be included first. js: str | Literal[True] | None default `= None` Custom js as a code string. The js code will automatically be executed when the page loads. For more flexibility, use the head parameter to insert js inside <script> tags.

Each parameter of the function corresponds to one input component, and the function should return a single value or a tuple of values, with each element in the tuple corresponding to one output component. inputs: Component | BlockContext | list[Component | BlockContext] | Set[Component | BlockContext] | None default `= None` List of gradio.components to use as inputs. If the function takes no inputs, this should be an empty list. outputs: Component | BlockContext | list[Component | BlockContext] | Set[Component | BlockContext] | None default `= None` List of gradio.components to use as outputs. If the function returns no outputs, this should be an empty list. api_name: str | None default `= None` defines how the endpoint appears in the API docs. Can be a string or None. If set to a string, the endpoint will be exposed in the API docs with the given name. If None (default), the name of the function will be used as the API endpoint. api_description: str | None | Literal[False] default `= None` Description of the API endpoint. Can be a string, None, or False. If set to a string, the endpoint will be exposed in the API docs with the given description. If None, the function's docstring will be used as the API endpoint description. If False, then no description will be displayed in the API docs. scroll_to_output: bool default `= False` If True, will scroll to output component on completion show_progress: Literal['full', 'minimal', 'hidden'] default `= "full"` how to show the progress animation while event is running: "full" shows a spinner which covers the output component area as well as a runtime display in the upper right corner, "minimal" only shows the runtime display, "hidden" shows no progress animation at all show_progress_on: Component | list[Component] | None default `= None` Component or list of components to show the pro

the runtime display, "hidden" shows no progress animation at all show_progress_on: Component | list[Component] | None default `= None` Component or list of components to show the progress animation on. If None, will show the progress animation on all of the output components. queue: bool default `= True` If True, will place the request on the queue, if the queue has been enabled. If False, will not put this event on the queue, even if the queue has been enabled. If None, will use the queue setting of the gradio app. batch: bool default `= False` If True, then the function should process a batch of inputs, meaning that it should accept a list of input values for each parameter. The lists should be of equal length (and be up to length `max_batch_size`). The function is then *required* to return a tuple of lists (even if there is only 1 output component), with each list in the tuple corresponding to one output component. max_batch_size: int default `= 4` Maximum number of inputs to batch together if this is called from the queue (only relevant if batch=True) preprocess: bool default `= True` If False, will not run preprocessing of component data before running 'fn' (e.g. leaving it as a base64 string if this method is called with the `Image` component). postprocess: bool default `= True` If False, will not run postprocessing of component data before returning 'fn' output to the browser. cancels: dict[str, Any] | list[dict[str, Any]] | None default `= None` A list of other events to cancel when this listener is triggered. For example, setting cancels=[click_event] will cancel the click_event, where click_event is the return value of another components .click method. Functions that have not yet run (or generators that are iterating) will be cancelled, but functions that are currently running will be allowed to finish. trigger_mode:

s .click method. Functions that have not yet run (or generators that are iterating) will be cancelled, but functions that are currently running will be allowed to finish. trigger_mode: Literal['once', 'multiple', 'always_last'] | None default `= None` If "once" (default for all events except `.change()`) would not allow any submissions while an event is pending. If set to "multiple", unlimited submissions are allowed while pending, and "always_last" (default for `.change()` and `.key_up()` events) would allow a second submission after the pending event is complete. js: str | Literal[True] | None default `= None` Optional frontend js method to run before running 'fn'. Input arguments for js method are values of 'inputs' and 'outputs', return should be a list of values for output components. concurrency_limit: int | None | Literal['default'] default `= "default"` If set, this is the maximum number of this event that can be running simultaneously. Can be set to None to mean no concurrency_limit (any number of this event can be running simultaneously). Set to "default" to use the default concurrency limit (defined by the `default_concurrency_limit` parameter in `Blocks.queue()`, which itself is 1 by default). concurrency_id: str | None default `= None` If set, this is the id of the concurrency group. Events with the same concurrency_id will be limited by the lowest set concurrency_limit. api_visibility: Literal['public', 'private', 'undocumented'] default `= "public"` controls the visibility and accessibility of this endpoint. Can be "public" (shown in API docs and callable by clients), "private" (hidden from API docs and not callable by clients), or "undocumented" (hidden from API docs but callable by clients and via gr.load). If fn is None, api_visibility will automatically be set to "private". time_limit: int | None default `= None` stream_every:

If fn is None, api_visibility will automatically be set to "private". time_limit: int | None default `= None` stream_every: float default `= 0.5` key: int | str | tuple[int | str, ...] | None default `= None` A unique key for this event listener to be used in @gr.render(). If set, this value identifies an event as identical across re-renders when the key is identical. validator: Callable | None default `= None` Optional validation function to run before the main function. If provided, this function will be executed first with queue=False, and only if it completes successfully will the main function be called. The validator receives the same inputs as the main function and should return a `gr.validate()` for each input value.

Gradio includes pre-built components that can be used as inputs or outputs in your Interface or Blocks with a single line of code. Components include preprocessing steps that convert user data submitted through browser to something that be can used by a Python function, and postprocessing steps to convert values returned by a Python function into something that can be displayed in a browser. Consider an example with three inputs (Textbox, Number, and Image) and two outputs (Number and Gallery), below is a diagram of what our preprocessing will send to the function and what our postprocessing will require from it. ![](/_app/immutable/assets/dataflow.FNuRzshD.svg)

Gradio - Introduction Docs
Creates an image component that can be used to upload images (as an input) or display images (as an output).
Description
https://gradio.app/docs/gradio/image
Gradio - Image Docs
**Using Image as an input component.** How Image will pass its value to your function: Type: `np.ndarray | PIL.Image.Image | str | None` Passes the uploaded image as a `numpy.array`, `PIL.Image` or `str` filepath depending on `type`. Example Code import gradio as gr def predict( value: np.ndarray | PIL.Image.Image | str | None ): process value from the Image component return "prediction" interface = gr.Interface(predict, gr.Image(), gr.Textbox()) interface.launch() **Using Image as an output component** How Image expects you to return a value: Type: `np.ndarray | PIL.Image.Image | str | Path | None` Expects a `numpy.array`, `PIL.Image`, or `str` or `pathlib.Path` filepath to an image which is displayed. Example Code import gradio as gr def predict(text) -> np.ndarray | PIL.Image.Image | str | Path | None process value to return to the Image component return value interface = gr.Interface(predict, gr.Textbox(), gr.Image()) interface.launch()
Behavior

Gradio - Image Docs
Parameters ▼ value: str | PIL.Image.Image | np.ndarray | Callable | None default `= None` A `PIL.Image`, `numpy.array`, `pathlib.Path`, or `str` filepath or URL for the default value that Image component is going to take. If a function is provided, the function will be called each time the app loads to set the initial value of this component. format: str default `= "webp"` File format (e.g. "png" or "gif"). Used to save image if it does not already have a valid format (e.g. if the image is being returned to the frontend as a numpy array or PIL Image). The format should be supported by the PIL library. Applies both when this component is used as an input or output. This parameter has no effect on SVG files. height: int | str | None default `= None` The height of the component, specified in pixels if a number is passed, or in CSS units if a string is passed. This has no effect on the preprocessed image file or numpy array, but will affect the displayed image. width: int | str | None default `= None` The width of the component, specified in pixels if a number is passed, or in CSS units if a string is passed. This has no effect on the preprocessed image file or numpy array, but will affect the displayed image. image_mode: Literal['1', 'L', 'P', 'RGB', 'RGBA', 'CMYK', 'YCbCr', 'LAB', 'HSV', 'I', 'F'] | None default `= "RGB"` The pixel format and color depth that the image should be loaded and preprocessed as. "RGB" will load the image as a color image, or "L" as black- and-white. See https://pillow.readthedocs.io/en/stable/handbook/concepts.html for other supported image modes and their meaning. This parameter has no effect on SVG or GIF files. If set to None, the image_mode will be inferred from the image file type (e.g. "RGBA" for a .png image, "RGB" in most other cases). sources: list[Literal['upload', 'webcam', 'clipboard']] | Literal['upload', 'webcam', 'clipboa

erred from the image file type (e.g. "RGBA" for a .png image, "RGB" in most other cases). sources: list[Literal['upload', 'webcam', 'clipboard']] | Literal['upload', 'webcam', 'clipboard'] | None default `= None` List of sources for the image. "upload" creates a box where user can drop an image file, "webcam" allows user to take snapshot from their webcam, "clipboard" allows users to paste an image from the clipboard. If None, defaults to ["upload", "webcam", "clipboard"] if streaming is False, otherwise defaults to ["webcam"]. type: Literal['numpy', 'pil', 'filepath'] default `= "numpy"` The format the image is converted before being passed into the prediction function. "numpy" converts the image to a numpy array with shape (height, width, 3) and values from 0 to 255, "pil" converts the image to a PIL image object, "filepath" passes a str path to a temporary file containing the image. To support animated GIFs in input, the `type` should be set to "filepath" or "pil". To support SVGs, the `type` should be set to "filepath". label: str | I18nData | None default `= None` the label for this component. Appears above the component and is also used as the header if there are a table of examples for this component. If None and used in a `gr.Interface`, the label will be the name of the parameter this component is assigned to. every: Timer | float | None default `= None` Continously calls `value` to recalculate it if `value` is a function (has no effect otherwise). Can provide a Timer whose tick resets `value`, or a float that provides the regular interval for the reset Timer. inputs: Component | list[Component] | set[Component] | None default `= None` Components that are used as inputs to calculate `value` if `value` is a function (has no effect otherwise). `value` is recalculated any time the inputs change. show_label: bool | None default `= None` if True, will disp

calculate `value` if `value` is a function (has no effect otherwise). `value` is recalculated any time the inputs change. show_label: bool | None default `= None` if True, will display label. buttons: list[Literal['download', 'share', 'fullscreen'] | Button] | None default `= None` A list of buttons to show in the corner of the component. Valid options are "download", "share", "fullscreen", or a gr.Button() instance. The "download" button allows the user to download the image. The "share" button allows the user to share to Hugging Face Spaces Discussions. The "fullscreen" button allows the user to view in fullscreen mode. Custom gr.Button() instances will appear in the toolbar with their configured icon and/or label, and clicking them will trigger any .click() events registered on the button. by default, all of the built-in buttons are shown. container: bool default `= True` If True, will place the component in a container - providing some extra padding around the border. scale: int | None default `= None` relative size compared to adjacent Components. For example if Components A and B are in a Row, and A has scale=2, and B has scale=1, A will be twice as wide as B. Should be an integer. scale applies in Rows, and to top-level Components in Blocks where fill_height=True. min_width: int default `= 160` minimum pixel width, will wrap if not sufficient screen space to satisfy this value. If a certain scale value results in this Component being narrower than min_width, the min_width parameter will be respected first. interactive: bool | None default `= None` if True, will allow users to upload and edit an image; if False, can only be used to display images. If not provided, this is inferred based on whether the component is used as an input or output. visible: bool | Literal['hidden'] default `= True` If False, component will be hidden. If "hidd

ovided, this is inferred based on whether the component is used as an input or output. visible: bool | Literal['hidden'] default `= True` If False, component will be hidden. If "hidden", component will be visually hidden and not take up space in the layout but still exist in the DOM streaming: bool default `= False` If True when used in a `live` interface, will automatically stream webcam feed. Only valid is source is 'webcam'. If the component is an output component, will automatically convert images to base64. elem_id: str | None default `= None` An optional string that is assigned as the id of this component in the HTML DOM. Can be used for targeting CSS styles. elem_classes: list[str] | str | None default `= None` An optional list of strings that are assigned as the classes of this component in the HTML DOM. Can be used for targeting CSS styles. render: bool default `= True` If False, component will not render be rendered in the Blocks context. Should be used if the intention is to assign event listeners now but render the component later. key: int | str | tuple[int | str, ...] | None default `= None` in a gr.render, Components with the same key across re-renders are treated as the same component, not a new component. Properties set in 'preserved_by_key' are not reset across a re-render. preserved_by_key: list[str] | str | None default `= "value"` A list of parameters from this component's constructor. Inside a gr.render() function, if a component is re-rendered with the same key, these (and only these) parameters will be preserved in the UI (if they have been changed by the user or an event listener) instead of re-rendered based on the values provided during constructor. webcam_options: WebcamOptions | None default `= None` placeholder: str | None default `= None` Custom text for the upload area.
