Why convert MP3 to M4A? Because it plays on anything ever made, while it sounds better than MP3 at the same size and is what Apple devices expect. The file is decoded by your browser and encoded again as M4A, 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 MP3.

Questions people ask

Does MP3 to M4A lose quality?

Any lossy conversion trades a little detail. At 192 kbps or more the difference is not audible. Converting from a lossy MP3 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.
