# Convert AAC to MP3

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

AAC is the codec behind M4A files, streaming services and much of broadcast audio; as a bare .aac stream it carries the same lossy audio without the MPEG-4 wrapper — and without proper tag 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 AAC 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.
