Calibre Integration
What is Calibre?
Calibre is a free, open-source eBook management application used by millions of readers to organize, convert, and manage their personal libraries. BookFusion's official Calibre plugin bridges your desktop collection with the cloud, so you never have to manually upload books again.
Jump straight to the plugin setup guide — it takes less than 5 minutes to configure.
How It Works
Your Calibre Library → BookFusion Plugin → BookFusion Cloud → All Your Devices
The plugin runs inside Calibre and communicates with your BookFusion account via a secure API key. When you trigger a sync, it uploads new or updated books and metadata — keeping everything consistent across web, iOS, and Android.
