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.
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.
