MP3 uses lossy audio compression. It usually saves space, but some audio information is discarded when WAV is encoded.
WAV is an audio container that commonly stores uncompressed PCM sound. PCM keeps the encoded samples without lossy compression, which is useful for editing and mastering but usually creates much larger files than MP3 or AAC.
WAV is supported by common media players and audio editors, including Windows Media Player, QuickTime and VLC. Support can depend on the codec stored inside the file.
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.
