What is a WEBM file?

A .WEBM file is a WebM video file. The WEBM file format is a video file format that was created by Google to store video content and implement compression standards for optimal video streaming on the Internet.

Royalty-free VP8 and VP9 video compression technologies are integrated into the digital video streams contained in this open Web media file format. The open-source Vorbis and Opus audio compression technologies are implemented into the digital audio streams contained in .webm files.

WebVTT text tracks are also stored in a WEBM file.

The file structure of the WEBM format is based on Matroska, a widely used digital media container. A supported Web browser or media player is needed to open these WEBM files. Web browsers like Google Chrome, Firefox, and others with support for HTML5 can be used to play .webm files.
