M4A (AAC audio) is what iPhones, Voice Memos, and Zoom’s audio-only recordings produce. Some older players, car stereos, and websites only accept MP3, so converting fixes compatibility in one step.
Drop the M4A in, choose a quality, and download the MP3. The conversion runs on your own device.

Frequently asked questions
Is my file uploaded to a server?
No. The converter (FFmpeg compiled to WebAssembly) runs inside your browser, so the file never leaves your device. That also means there is no upload wait, even for big videos.
Do Apple Lossless (ALAC) M4A files work?
Yes. Both AAC and ALAC M4A files convert to MP3.
Do protected iTunes purchases work?
No. Files with copy protection (DRM) can’t be converted. Regular AAC files and voice memos work fine.
