By default, uploaded files are limited to 200 MB each. You can configure this globally using the ``server.maxUploadSize`` configuration option. For more information on how to set configuration options, see |config.toml|_. Additionally, you can set a per-widget limit using the ``max_upload_size`` parameter. .. |config.toml| replace:: ``config.toml`` .. _config.toml: https://docs.streamlit.io/develop/api-reference/configuration/config.toml Parameters ---------- label : str A short label explaining to the user what this file uploader is for. The label can optionally contain GitHub-flavored Markdown of the following types: Bold, Italics, Strikethroughs, Inline Code, Links, and Images. Images display like icons, with a max height equal to the font height. Unsupported Markdown elements are unwrapped so only their children (text contents) render. Display unsupported elements as literal characters by backslash-escaping them. E.g., ``"1\. Not an ordered list"``. See the ``body`` parameter of |st.markdown|_ for additional, supported Markdown directives. For accessibility reasons, you should never set an empty label, but you can hide it with ``label_visibility`` if needed. In the future, we may disallow empty labels by raising an exception. .. |st.markdown| replace:: ``st.markdown`` .. _st.markdown: https://docs.streamlit.io/develop/api-reference/text/st.markdown type : str, list of str, or None The allowed file extension(s) for uploaded files. This can be one of the following types: - ``None`` (default): All file extensions are allowed. - A string: A single file extension is allowed. For example, to only accept CSV files, use ``"csv"``. - A sequence of strings: Multiple file extensions are allowed. For example, to only accept JPG/JPEG and PNG files, use ``["jpg", "jpeg", "png"]``. .. note:: This is a best-effort check, but doesn't provide a security guarantee against users uploading files of other types or type extensions. The correct handling of uploaded files is part of the app developer's responsibility. max_upload_size : int or None The maximum allowed size of each uploaded file in megabytes. If this is ``None`` (default), the maximum file size is set by the ``server.maxUploadSize`` configuration option in your ``config.toml`` file. If this is an integer, it must be positive and will override the ``server.maxUploadSize`` configuration option. accept_multiple_files : bool or "directory" Whether to accept more than one file in a submission. This can be one of the following values: - ``False`` (default): The user can only submit one file at a time. - ``True``: The user can upload multiple files at the same time. - ``"directory"``: The user can select a directory to upload all files in the directory and its subdirectories. If ``type`` is set, only files matching those type(s) will be uploaded. When this is ``True`` or ``"directory"``, the return value will be a list and a user can additively select files if they click the browse button on the widget multiple times. key : str or int An optional string or integer to use as the unique key for the widget. If this is omitted, a key will be generated for the widget based on its content. No two widgets may have the same key. help : str or None A tooltip that gets displayed next to the widget label. Streamlit only displays the tooltip when ``label_visibility="visible"``. If this is ``None`` (default), no tooltip is displayed. The tooltip can optionally contain GitHub-flavored Markdown, including the Markdown directives described in the ``body`` parameter of ``st.markdown``. on_change : callable An optional callback invoked when this file_uploader's value changes. args : list or tuple An optional list or tuple of args to pass to the callback. kwargs : dict An optional dict of kwargs to pass to the callback. disabled : bool An optional boolean that disables the file uploader if set to ``True``. The default is ``False``. label_visibility : "visible", "hidden", or "collapsed" The visibility of the label. The default is ``"visible"``. If this is ``"hidden"``, Streamlit displays an empty spacer instead of the label, which can help keep the widget aligned with other widgets. If this is ``"collapsed"``, Streamlit displays no label or spacer. width : "stretch" or int The width of the file uploader widget. This can be one of the following: - ``"stretch"`` (default): The width of the widget matches the width of the parent container. - An integer specifying the width in pixels: The widget has a fixed width. If the specified width is greater than the width of the parent container, the width of the widget matches the width of the parent container. Returns ------- None, UploadedFile, or list of UploadedFile - If accept_multiple_files is ``False``, returns either ``None`` or an ``UploadedFile`` object. - If accept_multiple_files is ``True`` or ``"directory"``, returns a list with the uploaded files as ``UploadedFile`` objects. If no files were uploaded, returns an empty list. The ``UploadedFile`` class is a subclass of ``BytesIO``, and therefore is "file-like". This means you can pass an instance of it anywhere a file is expected. Examples -------- **Example 1: Accept a single file at a time** >>> import streamlit as st >>> import pandas as pd >>> from io import StringIO >>> >>> uploaded_file = st.file_uploader("Choose a file") >>> if uploaded_file is not None: ... # To read file as bytes: ... bytes_data = uploaded_file.getvalue() ... st.write(bytes_data) >>> ... # To convert to a string based IO: ... stringio = StringIO(uploaded_file.getvalue().decode("utf-8")) ... st.write(stringio) >>> ... # To read file as string: ... string_data = stringio.read() ... st.write(string_data) >>> ... # Can be used wherever a "file-like" object is accepted: ... dataframe = pd.read_csv(uploaded_file) ... st.write(dataframe) **Example 2: Accept multiple files at a time** >>> import pandas as pd >>> import streamlit as st >>> >>> uploaded_files = st.file_uploader( ... "Upload data", accept_multiple_files=True, type="csv" ... ) >>> for uploaded_file in uploaded_files: ... df = pd.read_csv(uploaded_file) ... st.write(df) .. output:: https://doc-file-uploader.streamlit.app/ height: 375px **Example 3: Accept an entire directory** >>> import streamlit as st >>> >>> uploaded_files = st.file_uploader( ... "Upload images", accept_multiple_files="directory", type=["jpg", "png"] ... ) >>> for uploaded_file in uploaded_files: ... st.image(uploaded_file) .. output:: https://doc-file-uploader-directory.streamlit.app/ height: 375px ) rlrmrfrBrnrorprqrrrgrhrir7)r_file_uploader)rGrlrmrBrnrorprqrrrfrgrhrir7s r>rszFileUploaderMixin.file_uploadersL\!"""+"7-#  rN)rfrhrgr7ric  :t|}| t| tr| dkr tdt |j ||ddt || td|| hd|j |||||  }|r t|nd}t}||_ ||_ ||ng|jdd| | |_ ntjd|_ |d k(}|d uxs||_||_t%|j |_| |_t+| |j,_|t1||_t5|| }t7|j||||j8|j:| d }t=| t?| }|j jAd||t|j.tBryt|j.tDr+|j.Dcgc]}t|tBr|c}S|j.Scc}w)NrzThe `max_upload_size` parameter must be a positive integer representing the maximum file size in megabytes, or None to fall back to the `server.maxUploadSize` configuration option.F) default_valuewrites_allowedrs>rmrfrB) user_keyrfkey_as_main_identitydgrlrmrBrorizserver.maxUploadSizer)T)rCfile_uploader_state_value)on_change_handlerrqrr deserializer serializerr7 value_type)ri) layout_config)#rrEintrrrrrr FileUploaderProtoidrlrmmax_upload_size_mbr get_optionmultiple_filesaccept_directoryrform_idrgrrhvaluerrorAr#rMrZrr_enqueuer$rR)rGrlrmrBrnrorprqrrrfrhrgr7ri element_idnormalized_typefile_uploader_protois_directory_uploadserde widget_staterr8s r>r{z FileUploaderMixin._file_uploadersB"Sk  &?C0Oq4H'S   GG     #5*:;4 + "Vww"7 "?C4T:/1!+$)!.:O   #  &5D  25;5F5F&6  2 4{B !T ) @-@ *0C,&5dgg&>#'/$5U 6 ,,2  '-d|  $!"7W '  " "'**2   u$51   0    l((+ 6 l(($ /+11T!A{9SAT T!!!Us /HHctd|S)zGet our DeltaGenerator.r')r )rGs r>rzFileUploaderMixin.dgMs$d++rN)NNNNN)rlstrrmstr | Sequence[str] | NonerBLiteral[True, 'directory']rn Key | Nonero str | NonerpWidgetCallback | NonerqWidgetArgs | NonerrWidgetKwargs | Nonerf int | Nonergboolrhrrirr\list[UploadedFile])FNNNNN)rlrrmrrBLiteral[False]rnrrorrprrqrrrrrfrrgrrhrrirr\UploadedFile | None)rlrrBrrmrrnrrorrprrqrrrrrfrrgrrhrrirr\r)rlrrBrrmrrnrrorrprrqrrrrrfrrgrrhrrirr\r)NFNNNNN)rlrrmrrBr*rnrrorrprrqrrrrrfrrgrrhrrirr\(UploadedFile | list[UploadedFile] | None)rlrrmrrBr*rnrrorrprrqrrrrrfrrhrrgrr7zScriptRunContext | Nonerirr\r)r\r') r]r^r_r rsrr{propertyrrarNr>rcrcs +/"&&*!'+,5%.!!)! : !  !  !)! !$!$!!*!#! !!& 16+/"&&*"'+,5%."")" .
