Windows: Lifetime: $9.99 • Mac: From: $4.99

Your M4B audiobooks are stuck. They play in one app, on specific devices, and the moment you switch players you lose your chapters and progress.

Audiobook Converter Pro converts your M4B files to MP3, AAC, or FLAC — with every chapter perfectly preserved. Switch to any device, any app, any player. Your entire library, finally portable.

Pro features unlock batch conversion, parallel processing, recursive folder scanning, and flexible naming templates like {Album}/{TrackPadded}-{ChapterTitle} to organise your library exactly how you want it.

Available for Mac and Windows. Everything runs locally — no uploads, no accounts.

Features

Signature Feature

Chapter-Perfect Precision

Most converters flatten your audiobook into one long file and discard chapters entirely. Audiobook Converter Pro preserves every chapter marker from your original M4B — titles, timestamps, and order — so your MP3, AAC, or FLAC output behaves exactly like the original in any player that supports chapters.

Blazing Fast Conversions

Optimised conversion engine gets your audiobooks ready in record time. Full Pro unlocks parallel M4B and chapter processing — convert multiple files and chapters simultaneously.

Crystal Clear Quality

Convert to MP3, AAC, or FLAC with pristine audio quality. Choose from multiple bitrate settings up to 320 kbps, or go lossless with FLAC output.

Multi-File & Batch Processing

Full Pro: queue entire collections for conversion. Recursively scan folders to find and convert every M4B file in your library automatically. Choose your own output folder.

Advanced Editing & Naming Templates

Pro feature: edit filenames using metadata — title, artist, album. Apply flexible naming templates like {Album}/{TrackPadded}-{ChapterTitle} to organise your library exactly how you want it.

Intuitive Interface

Drag-and-drop your M4B files, select your output format, and convert. Designed for simplicity — even advanced Pro features are a single click away.

Retro-Inspired Design

A clean, focused interface with a distinctive retro colour palette that makes audiobook management a pleasure rather than a chore.

Privacy First

Everything runs locally on your device. No uploads, no cloud processing, no account required. Your audiobook library stays entirely under your control.
