Convert M4A to MP3

M4A is the AAC audio format used by Apple devices and many recorders. Some older players, car stereos and upload forms only accept MP3, so this page converts it for you.

Frequently asked questions

Can I convert songs bought on iTunes?

Songs sold today on iTunes are DRM free and convert normally. Old protected M4P files cannot be converted.

Will it lose quality?

Converting between lossy formats loses a little, but at 192 kbps or higher it is very hard to hear.

Which format should I convert to?

MP3 for playback anywhere, M4A for Apple devices, WAV or FLAC for editing and archiving, Opus for the smallest voice files.

Can I convert WhatsApp voice notes?

Yes. WhatsApp voice notes are Opus audio in an OGG container; drop them in and convert to MP3.

Does converting MP3 to WAV improve quality?

No. The WAV holds the same sound as the MP3, just uncompressed. It is useful for editors that need WAV, not for better quality.

Should I choose mono?

For speech, mono halves the file size with no loss in clarity. Keep stereo for music.

Is my audio uploaded?

No. FFmpeg converts it inside your browser.

Can I convert on my phone?

Yes. Audio conversion is light and quick in mobile browsers.
