Finally plays on everything
My whole voice memo library was stuck in M4A. Profi PDF converted them all to MP3 and now they play on every device I own. Should have done this ages ago.

Dead simple, works perfectly
Needed to convert some iTunes recordings for a client. Profi PDF did it in under a minute with zero quality drop. Exactly what I needed.
