download(custom_path=None, out=None, timeout=None)

Download this file. By default, the file is saved in the current working directory with its original filename as reported by Telegram. If the file has no filename, it the file ID will be used as filename. If a custom_path is supplied, it will be saved to that path instead. If out is defined, the file contents will be saved to that object using the out.write method.


custom_path and out are mutually exclusive.

  • custom_path (str, optional) – Custom path.
  • out (io.BufferedWriter, optional) – A file-like object. Must be opened for writing in binary mode, if applicable.
  • timeout (int | float, optional) – If this value is specified, use it as the read timeout from the server (instead of the one specified during creation of the connection pool).

The same object as out if specified. Otherwise, returns the filename downloaded to.

Return type:

str | io.BufferedWriter


ValueError – If both custom_path and out are passed.
