M4A to MP3

About M4A to MP3

What does M4A to MP3 do?

Converts M4A and AAC audio to MP3 so it plays everywhere. This tool reads the file with your browser's own built-in media player. Chrome, Edge and Safari read MP4, MOV, M4A, MP3, WAV, OGG and WebM. If your browser cannot play a file, the tool tells you so rather than producing an empty result.

Who is it for?

Creators preparing clips for a platform, teams that record meetings and need the content in writing, and anyone whose video file is too large to send.

Is it free?

Yes. M4A to MP3 is free with no account, no watermark on your output, no daily cap and no trial period. Because it runs on your own device it costs us nothing to run, which is why there is no catch.

Is it safe to use with confidential files?

Yes, and not because we promise to behave. M4A to MP3 never sends your file anywhere — the work happens in your browser. There is no upload, so there is no copy of your document in our systems at any point.

What file formats are supported?

Input: M4A, AAC. Output: MP3.

How to use it

1. 1

   Add your file

   Drag it onto the box above, or use Browse files. On a phone you can also take a photo or pick from your camera roll.

2. 2

   Check the settings

   Sensible defaults are already chosen. Most people never need to change them.

3. 3

   Run it

   The progress bar shows real progress, not a decorative animation. Everything happens on your device.

4. 4

   Preview the result

   Look at the output before you download. If it is not right, adjust a setting and run it again — nothing has been saved anywhere.

5. 5

   Download
