How to increase file size limit when sending documents through Python Telegram bot

I built a Python Telegram bot using the telepot library that can send files to users. However, I’m running into a problem with file size restrictions. Right now my bot can only send files up to 50 MB, but I know that Telegram actually supports much larger files. I read somewhere that Telegram allows files up to 1.5 GB in size. Is there a way to modify my bot or use different settings to take advantage of this higher limit? Maybe I need to use a different library or change some configuration? Any help would be great because I really need to send larger documents through my bot.

This is probably a telepot issue, not Telegram’s limits. Telepot’s been dead for years and struggles with handling large files. I had the same problem and switching to python-telegram-bot fixed it instantly. The official library actually supports Telegram’s Bot API 2.0, so you can upload files up to 2GB. You’ll have to rewrite some code since the syntax is different, but it’s pretty straightforward. Just ensure your server has enough RAM and a stable connection, as large uploads can take a long time and may timeout on unreliable connections.

for sure! try switching to python-telegram-bot, it’s way more reliable for larger files. telepot is kinda old and struggles with bigger uploads. just use send_document() and you’ll be able to handle those 1.5GB files without a prob!

You’re correct that the 50MB limit is due to telepot, not Telegram’s capabilities. While you could technically split larger files, that approach complicates the process for users. Switching to python-telegram-bot is a much better solution; it’s well-maintained and simplifies file uploads significantly. Just be aware that if you’re planning to send files up to 2GB, ensure your server has the appropriate resources and robust handling for potential timeouts during uploads.
