One way or another, you’ve found yourself with a .webm file and are wondering how to play it. This brief overview will get you doing just that!
Short background: A .webm file is a media file (audio/video). WEBM is an open format, and designed for the web. It’s a wrapper that contains audio and video – much like .MKV files. Since it’s an open format, it’s been pretty widely accepted and used on sites like YouTube.
To open a .webm file, you can use pretty much any modern web browser, including the current versions of Chrome, Firefox or Internet Explorer. You can also use media players such as VLC or Media Player Classic.
If you’re able to view the video below, you’re already set – it’s a .webm file. If it doesn’t play and you use Windows, you’ll need to install the WebM for IE filter.
