Part 1. What Is a WebM File?
A WebM video file is an open, royalty-free alternative to the patented H.264 and H.265. Contrary to popular belief, WebM file is not an audio or video compression format, instead it is a multimedia container format. With a container structure similar to MKV format, WebM incorporates both audio and video data into a single file - even if those elements use different types of encoding. For example, you can have a WebM file that contains AV1, VP9, or VP8 video and something like Vorbis or Opus for audio.
Since WebM is designed for sharing video on the web, files in the format can be embedded in web pages using HTML5 video tag. So it is not surprising to find that YouTube uses WebM record design in its HTML5 player. Modern web browsers like Edge, FireFox and Chrome include built-in support for WebM. However, you cannot open WebM files in Internet Explorer or Safari unless you install an external WebM plug-in. In the following section, you will learn how to play WebM files without any problem.
