AVI is a classic Microsoft video format from the 1990s. It offers broad compatibility and good quality but large, inefficient files, so it is mostly replaced by MP4 today — though it is still common in older archives.
AVI opens in Windows Media Player, VLC and most desktop players; for phones and browsers, converting to MP4 is the reliable choice.
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.
