Why convert M4A to MP3?
iPhone voice memos and iTunes purchases come as M4A, which some non-Apple apps and players won't open. Converting M4A to MP3 gives you a universally compatible audio file that plays on any device, app, or player.

How do I convert M4A to MP3 on Mac?
Open Picmal, drag your M4A files into the window, choose MP3 as the output format, set your quality, and click Convert.
Can I batch convert multiple M4A files at once?
Yes. Drag in as many M4A files (or a whole folder) as you like and Picmal converts them all to MP3 in one pass.
Does converting M4A to MP3 lose quality?
MP3 is lossy, and re-encoding from another lossy format can lose a little quality. Choosing a high bitrate (256–320 kbps) keeps it transparent for everyday listening.
