How to convert M4A to MP3
Drop the M4A and press Convert. The AAC audio is decoded and re-encoded as a 192 kbps MP3 with the LAME encoder, which is loaded the first time you use it. Drag the handles on the waveform to keep only part of the recording.
Step by step
- 01Drop the M4A file.
- 02Optionally drag the waveform handles to keep only part.

Where M4A files come from
iPhone Voice Memos, many Android recorders and DRM-free iTunes or Apple Music purchases are M4A files holding AAC audio. Older car stereos, some MP3 players, podcast tools and upload forms only accept MP3. Protected (DRM) tracks can't be converted.
Do you need to convert at all?
AAC to MP3 is a lossy-to-lossy step: the sound is decoded and compressed a second time. At 192 kbps the difference is barely audible for most listening, but if your device already plays M4A, keeping the original is the better choice.
Questions
Does M4A to MP3 lose quality?
A little in theory, because both formats are lossy. At 192 kbps it's barely audible for voice and normal music listening.
Will the MP3 be bigger than the M4A?
Often slightly. 192 kbps MP3 is about 1.4 MB per minute, and many M4A files use a lower bitrate for the same quality.
Can I convert an Apple Music song?
Only DRM-free purchases. Streamed or protected tracks can't be decoded by the browser.
Is my voice memo uploaded?
No. The audio is decoded and encoded in this browser tab.
