[Python] How to Send Files Larger than 2GB Using Telethon in Telegram

I'm using Telethon to send files on Telegram, but I've run into a problem with the 2GB file size limit. Telethon only allows sending files up to 2GB, while Telegram itself supports sending files up to 4GB through the official app.

Is there a way to bypass this 2GB limit using Telethon? I’ve tried client.send_file(), but it throws an error when the file exceeds 2GB.

Are there any workarounds? without splitting files or downloading and then re-uploading files.

I attempted to send a 2GB+ file using client.send_file() like this:

from telethon import TelegramClient

api_id = 123456
api_hash = 'api_hash'
session_string = 'session_string'

client = TelegramClient(session_string, api_id, api_hash)

async def send_large_file():
await client.send_file('me', 'large_video.mp4')

with client:
client.loop.run_until_complete(send_large_file())
