# Convert M4A to MP3

Convert M4A to MP3 right in your browser — free, private, nothing is uploaded. One-click re-encode for compatibility.

M4A wraps AAC audio in an MPEG-4 container — the format iTunes and Apple Music use. AAC squeezes better quality than MP3 out of the same bitrate, at the cost of slightly narrower support.

MP3 is the most widely supported audio format there is — a lossy codec that shrinks audio to a fraction of its uncompressed size and plays on virtually anything with a speaker.

Converting M4A to MP3 is a compatibility move: both formats are lossy, so the goal isn't quality — it's producing a file that fits sharing, podcasts and everyday listening. Expect the sound to stay essentially the same, with a small second round of encoding loss.
