Telegram's limits
Telegram's limit is 2 GB per file, or 4 GB with Telegram Premium, so you rarely have to compress. A smaller file still uploads faster, plays sooner for the people you send it to and uses less mobile data. We default to a quick-to-send size; pick 'Higher quality' if that matters more.
When it's worth compressing
- You're on mobile data or a slow connection.
- You're posting to a channel or a big group, where every viewer downloads the file.
- You recorded in 4K or high bitrate and the extra detail won't show on a phone screen.
