Why convert M4A to MP3? Because it sounds better than MP3 at the same size and is what Apple devices expect, while it plays on anything ever made. The file is decoded by your browser and encoded again as MP3, so nothing is uploaded and there is no queue.

Choose 192 kbps for a result that is indistinguishable from the source, 128 kbps for speech where size matters, or 320 kbps to keep everything from a high-quality M4A.

Questions people ask

Does M4A to MP3 lose quality?

Any lossy conversion trades a little detail. At 192 kbps or more the difference is not audible. Converting from a lossy M4A to another lossy format is best done once, not repeatedly.

Is there a file size or length limit?

No. The audio is processed on your device, so an hour-long file takes well under a minute on a typical laptop.

Can I convert several files at once?

Yes. Drop them all and they are converted one after another with the same settings, then offered as separate downloads or a ZIP.
