What M4A to MP3 does
M4A is the audio-only MP4 container used by iTunes, Apple Music downloads and voice memos, but many players and devices still only accept MP3. Upload your M4A file, pick an MP3 bitrate, and download a standard MP3 that plays almost anywhere. The conversion happens in your browser — your file is never uploaded.
How to use it
- Upload a M4A file.
- Choose a bitrate (128–192 kbps suits most music, 64–96 kbps is fine for speech) and optionally mix down to mono.
- Click Convert to MP3, preview the result, then download it.
Good to know
Converting between lossy formats can't add quality back — pick a bitrate at or above the original's for the best result. The file is decoded by your browser's built-in audio decoder, so if your browser can play the file, it can convert it. DRM-protected files can't be decoded.
Privacy
Decoding and MP3 encoding both run on your device. Nothing is sent to a server.
