Why Convert WAV to M4A?
M4A holds AAC audio — Apple's efficient, native format. Converting a big WAV to M4A gives you a much smaller file that plays natively on iPhone, iPad, Mac, AirPods, and CarPlay, with tags and artwork. AAC is lossy, so the M4A is smaller than the WAV and can't exceed its quality — but at 256–320 kbps it's transparent for almost all listeners. Need the reverse? Use M4A to WAV.
