Sign up to start using BookFab

To use BookFab, you will need to sign in with a DVDFab account. You can create one using an email address or log in with a Google account. Once signed in, you can access the program and try its available modules, although some features and usage limits depend on the version you are using. The interface is organized by product modules, so you can switch between eBook conversion, audiobook conversion, and audiobook creation tools depending on what you need.

Convert DRMed eBooks for broader compatibility

One of BookFab's main features is eBook conversion. The software supports books from platforms such as Amazon Kindle and Rakuten Kobo, and it can convert native formats such as AZW3, KFX, and KePub into more widely compatible formats like EPUB and PDF. According to the official site, the program is designed to preserve the original formatting and quality of the source files, including manga layouts, so the converted books can be read more easily across different eReaders and reading apps.

Download and convert audiobooks into open formats

BookFab also includes audiobook conversion tools. With supported modules, you can sign in through the built-in browser, access your audiobook library, download titles, and convert them into formats such as MP3, M4A, FLAC, WAV, or OPUS. The converted files retain chapters and metadata, which makes them easier to organize and play on different devices and media players. The software currently highlights support for platforms such as Audible, audiobooks.com, and other audiobook services that have been added over time.

Create audiobooks with AI voices

Another important part of BookFab is its AI audiobook creation feature. In addition to converting existing eBooks and audiobooks, the program can generate narration from plain text, TXT, and EPUB files. Text and TXT files can be exported as MP3 or OPUS, while EPUB files can be converted into M4B audiobooks. BookFab offers more than 20 AI voice presets and includes adjustable options such as prosody, expressivity, and silence, allowing you to customize how the narration sounds.

AI Voice Cloning for More Personalized Audiobooks

BookFab also includes an AI voice cloning feature that can generate a more personalized narration style from a short voice sample. In addition to its built-in AI voice presets, this feature gives users more flexibility when creating audiobooks, making the final narration sound more distinctive and natural.

The Best Companion to Calibre

BookFab also offers a free Calibre plugin that integrates the features of BookFab Kindle Converter into Calibre, making it easier to process and manage Kindle eBooks. As described on the product page, it is the best companion to Calibre, extending Calibre’s capabilities for handling Kindle books within a more convenient workflow. For users who already rely on Calibre to manage their digital library, BookFab works as a practical and powerful companion tool.
