Launched in 2010 and developed by Google, WebM is a royalty-free audiovisual format intended for HTML5 websites. As its name suggests, it's a web-oriented format and is an alternative to the patented H.264 and MP4 (MPEG4) formats.
However, since it's a relatively new file format, not every OS and default media player supports it, with Mac users having a lot of trouble opening and playing this type of file.
Therefore, today's article will teach you how to open WebM files on Mac and show you some of the top Mac WebM players you can use.
In this article
Why You Need a WebM Player for Mac
Although the included QuickTime media player on macOS is decent and supports a wide range of video formats, WebM isn't among them. You'll need a different and reliable third-party video player to open and play video files of the WebM format directly on your Mac, so stay with us as we'll soon discuss the top seven options.
How to Open a WebM File on Mac Without a Player
While it's undoubtedly better to get a proper WebM video player for Mac devices, there are ways to open these files without one. As WebM is a video format often associated with the internet, most modern browsers can play these files without issues.
Since WebM is Google's video format, the Chrome web browser has supported the WebM format the longest. Opera and Firefox included the necessary VP8 and VP9 video codecs for playing the HTML5 video format shortly after Chrome, while Microsoft Edge and Mac's own Safari were the last to add support.
Right-clicking and opening your WebM files with these web browsers will play the video without issues as long as your browsers are updated. You can also use WebM Project's detect feature to determine whether your browser is supported.
Best WebM Players for Mac
There are dozens of video apps, tools, and options for users who want a dedicated media player instead of playing WebM videos through their browser. After all, dedicated media players undoubtedly offer more advantages, such as:
- Specialized playback features
- Hardware acceleration and efficiency
- Offline playback
- Interface customization options
