What is a WEBM (WebM) file?

WebM (WEBM) is a freely-licensed file container designed for the Web. Specifically, it was designed to be compatible with HTML5, originally. It supports chapters, captions, subtitles, metadata tags, streaming, attachments, 3D codecs, 3D containers, and hardware players. WEBM compresses video streams with VP8 or VP9 codecs, and audio with Vorbis or Opus codecs.

 

How to open a WEBM file?

VLC media player and MPlayer can open WEBM files on any operating system (OS). Other good choices for opening WEBM include Winamp for Microsoft Windows OS, and Elmedia for Mac OS X.

 

Microsoft browsers do not have built-in WebM codecs. Therefore, install the codecs separately. However, most browsers support WEBM files.
