WebM Video File Format

What is “WebM” video file format?


WebM video, whose extension name is .webm, is an open and free multimedia file format. Designed for direct use on the web, WebM is compatible with Mozilla Firefox, Opera and Google Chrome, Internet Explorer, and since 2021 also with Safari under macOS.

Google regularly works on numerous improvements and optimizations to provide faster and better coding.


A brief history of the WebM format.


Developed by Google IO and launched in May 2010, the WebM video file format is based on the Matroska derived container, or .mkv.  Initially, the WebM allows working with VP8 video and audio streams encoded in Vorbis.

Originally thought of as a free alternative, WebM allows you to use HTML5 video and HTML5 audio elements. Conceived as a set of online multimedia proposals, the WebM project is developed in parallel with the WebP project, whose «p» is for «pictures», for a content of compression and decompression images of type JPEG, PNG and GIF.

In 2013, an update was made on WebM to be able to also manage the VP9 video encoder and the Opius audio encoder.


How to read and export a WebM video?


To play a WebM video, you have several possibilities: by direct integration on your internet browser or by using software on your computer.


It is integrated directly into Internet browsers like Google Chrome, Internet Explorer, Firefox or Opera that will read your .webm without the need to add an extension.
