Hi Fazier! I built M4AtoMP3.org because most converters make you upload your audio. This one converts everything locally in your browser - private, free, no sign-up. Feedback welcome!

Converting locally makes sense for voice notes and interviews people don't want on a random server. What bitrate do you use for MP3 by default, and do the tags (title, artist, cover art) carry over from the M4A? That's usually what quick converters lose.

Simple utility but solves a real problem - no signup friction is huge. Browser-based conversion is perfect for one-off needs. The speed and zero data concerns make this better than desktop apps.
