BookFab, developed by DVDFab, is a versatile tool for managing eBooks and audiobooks. It allows users to download and convert purchased content from platforms like Kindle, Audible, and Kobo into universal formats. Supported outputs include PDF and EPUB for eBooks, and MP3, M4A, or FLAC for audiobooks, enabling a seamless reading and listening experience across any device.

BookFab ensures that your downloads and conversions match the original. When converting eBooks, it keeps the original formatting, images, fonts, and book information (metadata). For audiobooks, BookFab lets you export your library in various formats, allowing you to choose depending on whether file size or sound quality is more important to you.

BookFab is the best companion to Calibre. It offers an official Calibre plugin that simplifies the process by combining steps that usually require separate tools right within Calibre. You can trigger BookFab directly inside Calibre to decrypt and convert protected eBooks with one click, and automatically import the finished files into your Calibre library to manage them. The entire process is automated and happens locally on your computer, saving you from manually finding files, dragging and dropping them, or constantly adjusting settings.

BookFab also features AI capabilities for turning text into speech. Its AudioBook Creator can turn plain text or TXT files directly into audio. It can also convert EPUB eBooks into audiobook formats like M4B. Additionally, it includes AI voice cloning for text-to-speech, letting the read-aloud voice match your preferences or the style of the content.
