Free WebM video converter: How to convert WebM file to MP4

convert WebM to MP4

WebM is an open-source, non-exclusive and royalty-free media file format designed for special use with HTML video. As a common alternative to commercial file formats, WebM is popularly used in compressing most video content, especially in YouTube which has an HTML5 version for mobile device access.

However, not all media players support this format. For instance, Windows Media Player can’t play a WebM file. So if you have an audio or video in WebM format that you can’t seem to play in your selected media player, it’s best to convert WebM to MP4 which is one of the most popular media file formats.
