How it works
- Pick an M4A file, such as an iPhone voice memo or a song bought from Apple Music.
- To convert M4A to MP3, the tool decodes the AAC sound stored inside the file.
- It encodes the sound again as MP3 at the bitrate you chose.
- A bitrate above the original adds no detail, because the sound cannot gain what it never had.
- Download the MP3.

Questions
How do I convert an iPhone voice memo to MP3?
Pick the M4A voice memo on this page and press Convert to MP3. The file is converted in your browser, so it is not sent to a server.
Does M4A to MP3 lose quality?
A very small amount. M4A and MP3 are both lossy formats, so the sound is compressed twice. A higher bitrate cannot bring back detail that the M4A does not have.
Why will some of my Apple Music songs not convert?
Copy-protected files, known as DRM, cannot be converted by this tool. Only files without that protection can be used.
Does choosing a higher bitrate make the MP3 sound better?
Not when the source is M4A. A bitrate above the original adds no quality, so the MP3 can be no better than the M4A it came from.
