M4A to MP3 converter

M4A is the format of iPhone voice memos and many podcast downloads. Convert it to MP3 for older car stereos, Windows apps and anywhere M4A won't play.

How to convert M4A to MP3

  1. Add your M4A files. iPhone voice memos, GarageBand exports and podcast downloads all work.
  2. Leave MP3 selected and choose the quality: 128 kbps for speech, 192 kbps for music.
  3. Click Convert and watch each file's progress.
  4. Download the MP3s one by one or together as a ZIP.

M4A vs MP3

M4A (AAC audio) sounds slightly better than MP3 at the same size and is Apple's default. MP3 is older but plays on absolutely everything: old car stereos, cheap MP3 players, smart speakers and every Windows app.

Frequently asked questions

How do I get voice memos off my iPhone?

In the Voice Memos app, tap a recording, then Share → Save to Files, or AirDrop it to a Mac. The file is an M4A you can add here.

Will converting M4A to MP3 lose quality?

Both are compressed formats, so there is a small loss. At 192 kbps it is inaudible for almost everyone; for voice memos, 128 kbps is plenty.

Why won't some M4A files convert?

Songs bought from iTunes before 2009 or downloaded from Apple Music are copy-protected and can't be converted by any browser tool. Your own recordings work fine.

Are my files uploaded?

No. Conversion runs in your browser on your own device, so your files never reach our servers, and large files are just as private as small ones.
