[M4A to MP3](https://edesy.in/tools/m4a-to-mp3) converts M4A audio to MP3 inside your browser. The files are never uploaded.

## How to Use

1. Click **Load Audio Engine**. It downloads once and takes a few seconds.
2. Add one or more M4A files (MP3 is already selected as the output) and click **Convert**.
3. Download each MP3.

## iPhone voice memos

In Voice Memos, tap the memo, then **Share > Save to Files**. Open this page in Safari, add the file from Files and convert it.

## Things to know

- Converting re-encodes the audio. Speech sounds the same; for music, keep the M4A as your master copy.
- Files are processed in your browser's memory. A few hundred MB works on most computers; phones handle less. Split long recordings with the [Audio Cutter](https://edesy.in/tools/audio-cutter) first.
