What is the WebM format?

Developed by On2, Xiph, Matroska, and Google, the WebM is a multimedia file format released in 2010. It was created as an alternative to use for HTML5 multimedia elements. Therefore, it's designed to share videos on the Web.

This format, which container structure resembles that of the Matroska (MKV) format, stores compressed audio and video data. Initially, this video format contained VP8 video and Vorbis audio, but since 2013 it also supports VP9 video and Opus audio.

Most web browsers support this format, as it's commonly used for online video streaming.


How to open WebM files?

If you want to convert videos to WebM files, it would be helpful if you knew how to open this kind of file. And you'll glad to know that this is really simple to do.

WebM format was designed for the Web, so you'll find WebM files embedded on websites in most instances. For that reason, the leading programs to open them are web browsers. Google Chrome, Mozilla Firefox, Microsoft Edge, Opera, and many more, support it natively so that you can use them to stream and open WebM files.

At first, Safari didn't support this format. As a result, people had to install a plugin in the browser to open and play WebM files with Safari. But since Safari 14.1 version, the Apple web browser started to support it natively.

You can also open and play WebM files with Android devices, as this Operating System supports it natively. And, finally, famous players like VLC media player, K-Multimedia Plater, and MPlayer also allow you open and play WEBM files.
