    MP3 vs ALAC

    ALAC is lossless, but it can't restore detail already removed by MP3's compression — the file just gets bigger. Convert when an app or editor requires ALAC.

    About MP3 and ALAC

    MP3: MP3 is the most widely supported audio format in the world. It uses lossy compression to make music and voice files small enough to share, while keeping quality good enough for everyday listening.

    ALAC: ALAC is Apple's lossless format. It compresses audio to roughly half the size of WAV with zero quality loss and plays natively in Apple Music, iTunes and on every iPhone. It is saved with the .m4a extension.
