Convert M4A to MP3
M4A is the audio format of iPhone voice memos, iTunes purchases and many phone recorders. This tool saves its sound as an MP3 that plays everywhere. The file is never uploaded: it is decoded and re-encoded as MP3 on your device. A file with no sound is refused, and if your browser cannot decode its audio, GRID16 says so instead of turning it into silence.

- Why convert M4A to MP3?
