Frequently asked
- Will I lose quality going from AAC to MP3?
- Both are lossy, so converting adds a little loss. Choose a bitrate at or above the original — 256 kbps is a safe pick for music.
- What about M4A files?
- M4A usually contains AAC audio. See our M4A to MP3 guide — it works the same way.
