Convert M4A to MP3 in three steps

M4A is Apple's audio format. Convert it to MP3 so it plays on every device, not just iPhones and Macs.

  1. Step 1

    Add your M4A

    Drop in an M4A from iTunes, Apple Music exports, or a voice memo — one file or a whole batch.

  2. Step 2

    Keep MP3, set quality

    MP3 is selected by default. Choose 128 kbps for voice or 256–320 kbps for music, then hit Convert.

  3. Step 3

    Download your MP3

    Save each file on its own or grab them all as a Zip. Your M4A files never leave your device.

What M4A files become

M4A is great on Apple devices but awkward elsewhere. MP3 plays everywhere.

iTunes music

Convert M4A songs to MP3 so they play on any car, console, or old player.

Voice memos

Turn iPhone M4A memos into MP3s you can send to anyone.

Audiobooks & podcasts

Make M4A audiobooks and podcasts playable on non-Apple apps.

Universal playback

M4A trips up some Android and Windows players; MP3 never does.

Batch convert

Then transcribe it

Why convert M4A to MP3

M4A wraps AAC audio in Apple's MPEG-4 container — efficient, but not as universally supported as MP3. Converting to MP3 keeps the audio at a quality most listeners can't tell apart while making it play on every device, app, and car on earth. It all runs locally in your browser, so your files stay private.

Frequently asked questions

Does converting M4A to MP3 lose quality?

M4A to MP3 is a lossy re-encode, but at 256–320 kbps the difference is inaudible for most music. 128 kbps is plenty for voice.

Can I convert iTunes M4A files?

Yes — non-DRM M4A files from iTunes, Apple Music exports, and voice memos all convert. DRM-protected purchases can't be converted.

Does my M4A leave my device?

No. Everything runs in your browser; the file is never sent anywhere.

Can I convert a batch of M4A files?

Yes — add as many M4A files as you like and download them together as a Zip.

Does it work on iPhone?

Yes — any modern browser on iOS, Android, Mac or Windows.

Can I get the M4A as text?

Yes. Convert it to MP3 first, then SlayScribe transcribes it in 99 languages.
