File size must not exceed 10 MB for images, 50 MB for videos, and a total limit of 50 MB when posting multiple files in one post

Like other social networks, Telegram has requirements for width, height, bitrate, audio rate, and other file parameters.

Possible reasons

The file does not meet Telegram's technical requirements. If a video does not meet the minimum requirements, it is automatically adapted before publication. As a result, its size may increase—for example, from 49 MB to 51 MB, which will lead to an error.

What to do?

Prepare files in advance considering the social network's requirements or with a small weight margin if unsure about the video's parameters.
