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

    About OPUS and ALAC

    OPUS: Opus is a modern, highly efficient codec used by WhatsApp voice notes, Discord, Zoom and WebRTC calls. It sounds excellent even at very low bitrates.

    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.
