How to use the M4A to MP3 converter

  1. Choose .m4a or .aac files — iPhone Voice Memos, WhatsApp audio exports, iTunes downloads (not DRM-protected).
  2. Pick the quality and mono for speech.
  3. Download the MP3 versions.

M4A (AAC audio) is the default on iPhone and in Apple Music, but some car radios, Windows apps, websites and older devices only accept MP3. Converting a voice memo to MP3 at 96–128 kbps mono keeps it small and universally playable. Files with copy protection (DRM) cannot be converted.
