MKV (Matroska) is a flexible open container that holds high-definition video, multiple audio tracks and subtitles in one file. It is popular for movies and archiving, but is not natively supported by every device or browser.
MKV plays in VLC and most modern media players; some phones, browsers and TVs need it converted to MP4 first.
MP3 is the world’s most popular audio format. Its lossy compression shrinks music and audio to a fraction of the original size while keeping quality good enough for almost any use, which is why it plays on virtually every device and app.
MP3 plays everywhere — any music app, browser, phone, car stereo, and the default player on Windows, macOS, Android and iOS.
