The web needed a high-quality open video option optimized for browser delivery and implementable without the same licensing concerns associated with some older media stacks.
WebM is an important delivery and interchange format in browser-oriented, open-media, and web-optimized video workflows.
WEBM is closely associated with WebM Project.
