What is a WEBM file?

A WEBM file is a video saved in the WebM format, an open, royalty-free format designed for sharing video on the web. WebM uses a container structure similar to the Matroska (.MKV) video format, which stores both audio and video data. Video is compressed using a VP8 or VP9 codec, and audio is compressed with either the Vorbis or Opus audio codec.

Several modern web browsers, such as Chrome, Edge and Firefox, include built-in support for the WebM format. If your browser does not support WebM (like Safari or Internet Explorer), you will need to install a WebM plug-in to play WebM media files.

WebM is an open-source, royalty-free alternative to the patented H.264 and H.265 standards. Since it is 100% free, the technology is suitable for commercial and non-commercial applications.

NOTE: Google acquired ON2, the original developer of VP8 technology, in 2010. The WebM Project represents Google in the Alliance for Open Media.

How do I open a WEBM file?

Since the WebM format was designed for the web, WEBM files are typically embedded in webpages (using an HTML5 <video> tag). In most cases, you can play a WebM audio or video file within a web browser using the on-screen controls. If you get an error saying the format is not supported, you can download the free WebM plug-in, install it in your browser, then reload the page.

You can also open and play a WEBM video in VLC media player (cross-platform). Additionally, you can convert WEBM videos to other formats in Miro Video Converter (Windows, Mac) or HandBrake (cross-platform).
