What is M4A and Why Convert It to MP3?
M4A is an audio file encoded with AAC (or Apple Lossless) inside an MPEG-4 container - the default format for Apple Voice Memos, iTunes purchases, and many recorders. While M4A offers good quality, MP3 remains the most universally supported audio format across every player, car stereo, editor, and device. Our M4A to MP3 converter re-encodes your file locally so you get maximum compatibility without uploading anything.
