MP4 is the most widely supported video format in the world. It packs high-quality video and audio into a compact file that plays on virtually every device, browser and app, which makes it the safe default for sharing and uploading.
MP4 plays everywhere: any browser, phone, smart TV, and the default video player on Windows, macOS, Android and iOS.
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.
