M4A to MP3
Convert M4A files, such as iPhone voice memos and iTunes purchases, to MP3 at 128, 192 or 320 kbps. Free, no sign-up, and no upload: the file is converted right in your browser.
Apple Lossless (ALAC) M4A files may not open in every browser. If yours doesn’t, try Safari or Chrome.
How it works
- Drop an M4A file into the box, or click to choose one. On iPhone, share the voice memo to Files first.
- Pick a bitrate: 128 kbps is plenty for voice memos, 192 or 320 kbps for music.
- Click “Convert to MP3”. The MP3 downloads automatically, and you can play it right on the page.
FAQ
Is it free, and is my file uploaded?
It’s completely free with no account. Your browser decodes the M4A and the MP3 encoder runs on your device, so personal recordings never leave your phone or computer.
What is an M4A file, and why convert it?
M4A is AAC audio stored in an MP4 container. It’s the default on iPhone and in iTunes and Apple Music, but some car stereos, older MP3 players and editing apps only accept MP3.
Can I convert songs bought on iTunes or Apple Music?
Songs purchased on the iTunes Store are DRM-free M4A files and convert fine. Copy-protected files, such as Apple Music downloads or old protected .m4p files, can’t be decoded by the browser and won’t convert.
Will the MP3 sound worse than the M4A?
Both are lossy formats, so re-encoding loses a little detail. At 192 or 320 kbps the difference is very hard to hear; for voice memos 128 kbps is more than enough.
