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.
M4A is an audio format that usually holds AAC-encoded sound in an MP4 container. It is Apple’s standard for music downloads and voice memos, offering great quality at small sizes and playing natively across the Apple ecosystem.
M4A plays in Apple Music/iTunes, QuickTime, VLC and most modern media players; on older devices, convert it to MP3.
