What is WebM?

WebM is an open, royalty-free video format from Google based on the Matroska container. Designed for web streaming — smaller files, good quality. Supported natively by Chrome, Firefox, and Edge. Limited support on Safari (check caniuse.com).

WebM vs MP4 for web video

Feature	WebM (VP9/AV1)	MP4 (H.264)
Licensing	Royalty-free	Requires licensing
File size	Smaller (VP9/AV1)	Larger at same quality
Safari support	Limited	Full
Chrome/Firefox	Full	Full
Best codec	AV1 (newest)	H.264 (universal)

Best practice: serve both formats

<video controls>
  <source src="video.webm" type="video/webm">
  <source src="video.mp4" type="video/mp4">
</video>

Browsers pick the first format they support. Chrome/Firefox use WebM (smaller). Safari falls back to MP4 automatically.

Frequently Asked Questions

What is AV1 and why should I care?

AV1 is the newest open-source video codec — developed by the Alliance for Open Media (Google, Mozilla, Netflix, etc.). It offers ~30% better compression than VP9 and ~50% better than H.264, while being royalty-free. Our sample-av1.webm lets you test AV1 support.

Does Safari support WebM?

Safari 14.1+ (macOS Big Sur) has partial WebM support — VP8/VP9 in some configurations. Safari 16+ has better support. For reliable cross-browser delivery, always include an MP4 fallback using the <video> source element.

Should I use VP8 or VP9?

VP9. It offers ~30% better compression than VP8 at the same quality and has broad browser support (Chrome, Firefox, Edge). VP8 is only needed if you must support very old browser versions.

How do I create WebM files?

FFmpeg: ffmpeg -i input.mp4 -c:v libvpx-vp9 -crf 30 -b:v 0 output.webm. For AV1: ffmpeg -i input.mp4 -c:v libaom-av1 -crf 30 output.webm. Note: AV1 encoding is significantly slower than VP9.
