Bindette

What it does

Bindette joins MP3, M4A, M4B, AAC, FLAC, WAV, AIFF and CAF files into a single .m4b audiobook with chapters, a cover and its details, ready for Apple Books and every audiobook player. On your Mac, iPhone and iPad, where one purchase covers all three, and on Android.

• Drop, and it's done. Files go in natural order (Chapter 2 before Chapter 10) or by their track numbers; each becomes a chapter named from its tags or file name; the title, author, narrator and cover come from the files.
• Fast, and without loss. When every file is AAC of one kind, the audio is copied as it is: a 20-hour book in seconds. Anything else is encoded as AAC, several files at once.
• Chapters your way. Rename, merge and split chapters; split by silence with a waveform preview; import and export chapter lists as text or CUE sheets. M4B inputs keep their chapters.
• Every detail. Title, author, narrator, series, year, genre, description, publisher, copyright, and a cover you drop, paste, pick from a file and crop to a square.
• Plays everywhere. Each book carries both a QuickTime chapter track and a Nero chapter list, and is checked after it is written.

Requires macOS 14 Sonoma or later; on iPhone and iPad, iOS and iPadOS 17 or later; on Android, Android 8.0 or later.

Privacy in one paragraph

Bindette never connects to the internet. Your audio, covers and books stay on your device. There is no account, no tracking and no analytics, and no data is collected. The full privacy policy says the same at more length.
