How do I compress a file to fit GitHub?

Use the compressor on this page. It handles video, images and PDFs, targets 25MB, runs entirely in your browser with no upload, and measures the output to confirm it is under the limit rather than estimating it.

Limit reference

GitHub file size limit

Aim for

25MB

As of 11 Oct 2026, GitHub accepts files up to 25 MiB through the browser, warns above 50 MiB on a git push, and blocks anything over 100 MiB outright. Because those are MiB and not MB, a file under 25,000,000 bytes is always safe.

By plan

GitHub limits by tier

What the same file is allowed to be, depending on the plan you are on or the route you send it by. Only the default free path is ever offered as a preset — the rest are here so you can see whether changing route is cheaper than compressing.

Browser upload

25MB

Push warning

50MB
