Frequently Asked Questions

Yes, M4B is an accepted input extension. Check the saved MP3 before relying on it; do not assume audiobook chapters or tags will carry over.

No. M4A is a container commonly used for AAC or Apple Lossless audio. The source encoding affects what conversion can preserve. Keep the original file and do not assume that its extension alone tells you whether the audio is lossless.
