An MP3 opens on Windows, Android, and the web without asking the other person to install anything.

Remove background noise from audioShould I convert M4A to MP3 or keep the M4A?
Keep the M4A if the app accepts it, since it is already compressed and converting adds a second lossy step. Convert M4A to MP3 when a device or form needs MP3.

Frequently asked questions
How do I convert M4A to MP3 for free?
Open this page, choose the M4A, keep MP3 selected, and select Convert to MP3. Your browser does the work, so it is free, needs no account, and adds no watermark.
Can I convert an iPhone voice memo to MP3?
Yes. Share the memo to Files, open this page in Safari, choose the file, and save the MP3 back to Files.
Does converting M4A to MP3 lose quality?
A little, because both formats are lossy and the audio is encoded a second time. At 192 kbps the difference is hard to hear on voice. Keep the M4A if the app accepts it.
Is my file uploaded?
No. The M4A is read and the MP3 is written in your browser. Nothing is sent to EraseNoise or anyone else.
Why does my M4A show an error?
It may be an M4P with copy protection, which browsers cannot decode, or the file may be damaged. Unprotected M4A from recorders and Zoom converts normally.
Can I convert several M4A files into one MP3?
Use the merge audio page: add the files in order, pick MP3, and they are joined into one file.
