What is a WEBM File?
The WEBM file contains video content in royalty-free WebM format, which is a container format. The video content inside a WEBM file is compressed using either the VP8 or VP9 codec, and may also contain audio content which is compressed ith either Opus or Vorbis codec. This video format is mostly used for sharing videos on the web.
Many modern web browsers support the WebM format natively so you can play the videos in them directly. However, some browsers, such as Safari, do not support this format. In that case, you can install extensions to play a .WEBM video file.
