github video size limit.

A file budget divided by duration gives you a bitrate. For a 30 second clip targeting 4 MB with 96 kbps of audio:

(4,194,304 bytes x 8) / 30s / 1000 = 1118 kbps total
1118 - 96 kbps audio  = 1022 kbps of video

Basketweaver runs this for you and steps the resolution down when the numbers cannot be met at a watchable quality.

Open the converter with the GitHub target already set, or convert on your phone:

GitHub accepts .mp4, .mov, and .webm in issues, pull requests, and comments, and plays them inline. Their docs note that video codec support is browser specific and recommend H.264 for the widest reach, so a WebM demo clip is best paired with a plain-text description for anyone whose browser will not decode it.

What is the largest video I can upload to GitHub?

GitHub accepts uploads up to 10 MB. That figure was read on 2026-09-01 from GitHub's own documentation.

Is the limit higher on GitHub Paid plan?

Yes. Paid plan raises the ceiling to 100 MB, against 10 MB otherwise. A file under 4 MB clears both, so converting removes the need to care which you have.

How do I get a video under 10 MB?

Convert it to WebM with Basketweaver. Output is capped at 4 MB, which is inside GitHub's 10 MB ceiling, so a converted clip always fits. Conversion runs on your own device or in your own browser.

What bitrate do I need for a 30 second clip?

Budget 1022 kbps of video alongside 96 kbps of audio. That is the target size in bits divided by the duration, minus the audio track. Basketweaver works this out for you and lowers the resolution when the maths cannot be met.

Is this limit still current?

It was checked on 2026-09-01 against GitHub's own documentation. Platforms change these quietly, so the source is linked on this page for you to confirm.
