Convert AAC to MP3

AAC is efficient but not as universally accepted as MP3, which still plays on absolutely everything. This re-encodes an AAC (or .m4a) file to MP3 with WebCodecs right in your browser, so the audio is never uploaded and there is no cap on size or count.

Runs entirely in your browser — your file is never uploaded.

Frequently asked questions

Does converting change the audio quality?

Re-encoding between lossy formats involves a small quality trade-off, but at the default bitrate it is hard to tell from the source. If you need the original quality preserved, keep the AAC; convert when you need MP3’s universal compatibility.

Is the file uploaded?

No. The conversion runs with WebCodecs on your own device, so the audio never leaves the browser — no account, no quota, no size limit. Chrome, Edge and Firefox work best.
