About the WebM Format

WebM is an open-source multimedia container format launched by Google in 2010 as a royalty-free alternative to proprietary video formats. Built on the Matroska container, WebM pairs VP8, VP9, or AV1 video codecs with Vorbis or Opus audio codecs. It was designed from the ground up for efficient HTML5 web video delivery, offering smaller file sizes and faster loading times than many traditional video formats while maintaining high visual quality.

WebM is optimized for web streaming and is supported natively by all major modern browsers including Chrome, Firefox, Edge, and Opera. Its open-source, royalty-free licensing makes it particularly attractive for platforms that need to serve video at scale without codec licensing fees. The main limitation is that WebM has less support on native device players and older hardware compared to MP4, making it best suited for web-first video distribution rather than offline or cross-device playback.
