WebM is an audiovisual media file format.[5] It is primarily intended to offer a royalty-free alternative to use in the HTML5 video and the HTML5 audio elements. It has a sister project, WebP, for images. The development of the format is sponsored by Google, and the corresponding software is distributed under a BSD license.
The WebM container is based on a profile of Matroska.[3][6][7] WebM initially supported VP8 video and Vorbis audio streams. In 2013, it was updated to accommodate VP9 video and Opus audio.[8] It also supports the new AV1 codec.[9]
