Universal sharing. MP3 is the audio format that plays absolutely everywhere — when in doubt, ship MP3.
Editor compatibility. Some older audio editors and DAWs don't accept M4A. Convert first.

M4A typically uses AAC, which is already a lossy codec. Converting M4A to MP3 is a lossy-to-lossy transcoding — use 320 kbps for the cleanest result.
