WebM is an open, royalty-free video format built for the web. It streams efficiently at small file sizes and is supported natively by modern browsers, which makes it ideal for online video and HTML5 players.
WebM plays in all current browsers (Chrome, Firefox, Edge) and VLC; older devices or editing software may need it converted to MP4.
AAC (Advanced Audio Coding) is the successor to MP3, delivering better sound at the same file size. It is the default for Apple Music, YouTube and most streaming services, and is supported across virtually all modern devices.
AAC plays in Apple Music/iTunes, QuickTime, VLC and on nearly all modern phones, browsers and players.
