About WebM files
WebM is based on the Matroska container format (.mkv) but restricted to VP8/VP9 video and Vorbis/Opus audio codecs. Google created it as a royalty-free alternative to H.264/MP4. The format is optimized for web delivery.
VP9, the video codec used in our sample files, offers good compression efficiency. YouTube uses VP9 extensively for video delivery. Browser support is strong across Chrome, Firefox, and Edge, though Safari added support only recently.
For broader device compatibility, our MP4 samples work everywhere. For other container formats, see our AVI samples.
