How to Convert Audio to MP3 on a Mac

macOS leans on the Apple ecosystem, so a lot of your audio is M4A. The Music app can convert in some cases, but it's fiddly and ties you to your library. mp3bat converts any supported audio in Safari or Chrome, on your Mac, with no upload.

Step by step

  1. Open the converter. Open the mp3bat converter in Safari, Chrome, or Firefox on your Mac.
  2. Drag in your file. Drag the audio file from Finder onto the drop zone, or click to choose it.
  3. Pick a bitrate. Choose 320 kbps for the best quality or a lower bitrate for a smaller file.
  4. Convert. Click Convert to MP3 — your Mac does the encoding locally, in the browser tab.
  5. Download. Click Download to save the MP3, then drag it wherever you need it.

FAQ

Can the Music app convert M4A to MP3?

It can, via import settings, but it's clunky and keeps files inside your library. A browser converter is faster for a one-off file and doesn't touch your Music library.

Will this work in Safari?

Yes. mp3bat uses the standard Web Audio API, which Safari supports. Everything runs on your Mac — no file is uploaded.
