How to upload file?

As says official Telegram Bot API documentation there are three ways to send files (photos, stickers, audio, media, etc.):

If the file is already stored somewhere on the Telegram servers or file is available by the URL, you don't need to reupload it. But if you need to upload new file just use subclasses of InputFile. Here is available three different builtin types of input file:

Be respectful with Telegram

Instances of InputFile is reusable. That's mean you can create instance of InputFile and sent this file multiple times but Telegram is not recommend to do that and when you upload file once just save their file_id and use it in next times.

Upload from file system

By first step you will need to import InputFile wrapper:

from aiogram.types import FSInputFile

Then you can use it:

cat = FSInputFile("cat.png")
agenda = FSInputFile("my-document.pdf", filename="agenda-2019-11-19.pdf")

FSInputFile(...)

Argument Type Description
path Union[str, Path] File path
filename Optional[str] Custom filename to be presented to Telegram
chunk_size int File chunks size (Default: 64 kb)

Upload from buffer

Files can be also passed from buffer (For example you generate image using Pillow and the want's to sent it to the Telegram):

Import wrapper:

from aiogram.types import BufferedInputFile

And then you can use it:

text_file = BufferedInputFile(b"Hello, world!", filename="file.txt")

BufferedInputFile(...)

Argument Type Description
buffer bytes File path
filename str Custom filename to be presented to Telegram (Required)
chunk_size int File chunks size (Default: 64 kb)

Also you can read buffer from file:

file = BufferedInputFile.from_file("file.txt")

BufferedInputFile.from_file(...)

Argument Type Description
path Union[str, Path] File path
filename Optional[str] Custom filename to be presented to Telegram
chunk_size int File chunks size (Default: 64 kb)

Upload from url

If you need to upload a file from another server, but the direct link is bound to your server's IP, or you want to bypass native upload limits by URL, you can use URLInputFile.

Import wrapper:

from aiogram.types import URLInputFile

And then you can use it:

image = URLInputFile("https://www.python.org/static/community_logos/python-powered-h-140x182.png", filename="logo.png")

URLInputFile(...)

Argument Type Description
url str URL
filename Optional[str] Custom filename to be presented to Telegram
chunk_size int File chunks size (Default: 64 kb)
timeout int Total timeout in seconds (Default: 30)
