Why convert M4A to MP3
Many car stereos, older music players, some audio editors and upload forms accept MP3 but not M4A. An MP3 plays on all of them.
Pick the right quality
An M4A is already compressed, so converting it cannot add detail that is not there. Pick "Very good" for voice memos and podcasts, and "Best" for music, so the MP3 loses as little as possible.

Why your audio never leaves your computer
Online converters upload your file to their servers, convert it there and send it back. That is slow for long recordings, so free plans cap the length or the number of files, and your recording sits on someone else's computer.
Here your own computer does the work, inside this tab. Nothing is uploaded, so there is nothing to cap: no length limit, no daily limit and no sign-up.
Questions
How big will the MP3 be?
About 1.4 MB per minute at "Very good", 1 MB per minute at "Good" and 2.4 MB per minute at "Best".
Does it work for long recordings?
Yes. There is no length or size limit; a lecture or an all-day recording works the same way.
Need the words instead of the sound?
Use voice memo to text to get a transcript of the recording.
Can I convert several files at once?
Yes. Choose or drop several files together. They are converted one after another with the same settings, and you can download each one or all of them in one ZIP.

No. It is converted inside this browser tab and saved straight back to your computer.

Recent Chrome, Edge and Safari on a computer.
Can I use a video file?
