Convert M4A to MP3
M4A is the container Apple uses for AAC audio: voice memos, store purchases and GarageBand exports are all typically M4A. The audio quality is good, but plenty of non-Apple players, car stereos and older devices only understand MP3. Converting locally in your browser gives you a file that plays on any device, without uploading the recording.

Frequently asked questions
What is the difference between M4A and MP3?
Both are lossy, but M4A usually wraps AAC audio, while MP3 is the older format with the broadest device support.
Can I convert several voice memos at once?
Yes, drop in multiple M4A files and they are all converted in one batch.
Are my files uploaded to a server?
No. The conversion is performed in your browser, so the audio never leaves your device.
