Use this page when an M4A file won't play where you need it. It happens with iPhone voice memos, iTunes tracks and WhatsApp audio. MP3 is the format almost every player, phone and car stereo understands.
Add your M4A file and the converter turns it into an MP3 at 192 kbit/s. That is the default setting. You can add several files at once and convert them in one go.
The conversion runs inside your browser. Your file is never uploaded anywhere, so the audio stays on your device. There is no size limit except the memory of your device, so a very long recording may be slow or may not fit on an older phone. Once the page is open, it keeps working even if you go offline.
There is no sign-up, no e-mail to enter and no watermark on the result. It works in any modern browser on Windows, macOS, Linux, Android and iPhone.
One thing to know: M4A and MP3 are both compressed formats. Converting from one to the other can't bring back detail that was already lost, so the MP3 will not sound better than your original M4A.
