download_media()

async Client.download_media()

Download the media from a message.

Usable by Users Bots
Parameters:
  • message (Message | str) – Pass a Message containing the media, the media itself (message.audio, message.video, …) or a file id as string.

  • file_name (str, optional) – A custom file_name to be used instead of the one provided by Telegram. By default, all files are downloaded in the downloads folder in your working directory. You can also specify a path for downloading files in a custom location: paths that end with “/” are considered directories. All non-existent folders will be created automatically.

  • in_memory (bool, optional) – Pass True to download the media in-memory. A binary file-like object with its attribute “.name” set will be returned. Defaults to False.

  • block (bool, optional) – Blocks the code execution until the file has been downloaded. Defaults to True.

  • progress (Callable, optional) – Pass a callback function to view the file transmission progress. The function must take (current, total) as positional arguments (look at Other Parameters below for a detailed description) and will be called back each time a new file chunk has been successfully transmitted.

  • progress_args (tuple, optional) – Extra custom arguments for the progress callback function. You can pass anything you need to be available in the progress callback scope; for example, a Message object or a Client instance in order to edit the message with the updated progress status.

Other Parameters:
  • current (int) – The amount of bytes transmitted so far.

  • total (int) – The total size of the file.

  • *args (tuple, optional) – Extra custom arguments as defined in the progress_args parameter. You can either keep *args or add every single extra argument in your function signature.

Returns:

str | None | BinaryIO – On success, the absolute path of the downloaded file is returned, otherwise, in case the download failed or was deliberately stopped with stop_transmission(), None is returned. Otherwise, in case in_memory=True, a binary file-like object with its attribute “.name” set is returned.

Raises:

ValueError – if the message doesn’t contain any downloadable media

Example

Download media to file

# Download from Message
await app.download_media(message)

# Download from file id
await app.download_media(message.photo.file_id)


# Keep track of the progress while downloading
async def progress(current, total):
    print(f"{current * 100 / total:.1f}%")


await app.download_media(message, progress=progress)

Download media in-memory

file = await app.download_media(message, in_memory=True)

file_name = file.name
file_bytes = bytes(file.getbuffer())
