M4A wraps AAC audio in Apple's MPEG-4 container — efficient, but not as universally supported as MP3. Converting to MP3 keeps the audio at a quality most listeners can't tell apart while making it play on every device, app, and car on earth. It all runs locally in your browser, so your files stay private.
