WebM is an open source video format that is designed primarily to stream high quality videos in a webpage using HTML5 video tag. WebM initially used VP8 and Vorbis as video and audio streams. Later it was updated to support VP9 video and Opus audio.

WebM is specifically built for the web and is addressing the needs for users to stream videos on a webpage. That is to say, you can play videos directly in a webpage without installing plug-ins (just imagine flash player you used years ago). Nowadays, a growing number of popular sites and web browsers are using WebM videos, like YouTube, 4chan, Chrome, Firefox and Opera. Some web browsers may need to install components for the support of WebM videos like IE and Safari.
