What is WebM?

WebM is an open, royalty-free video format developed by Google for web delivery. It uses VP8/VP9 or AV1 video with Vorbis or Opus audio — providing excellent compression and quality for streaming without codec licensing costs. WebM is the preferred open format for HTML5 video in browsers that avoid proprietary codecs.

Common uses for WebM

  • Open-source and royalty-free web video without licensing concerns
  • Browser-based video in HTML5 players
  • Web applications and games using open video formats
Note: Limited native support on Apple devices — Safari does not support VP8/VP9 WebM well; iOS and macOS prefer H.264 MP4.

Compatibility: Chrome, Firefox, Edge, Android. Limited or no support on Safari and iOS without workarounds.
