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.
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.
