How to Strip LCP DRM with Calibre DeDRM Plugin
Compared to Thorium Book Extractor, Calibre is limited as it only supports LCP DRM version 1.0. In contrast, Thorium Book Extractor can handle all EPUBs encrypted with LCP DRM, including version 2.0 and newer. For a step-by-step walkthrough, please refer to this detailed guide.
Note: While Calibre is a versatile library manager, using it for LCP DRM removal is often inefficient due to complex plugin requirements and compatibility issues with newer DRM versions. For a more user-friendly experience, we recommend automation tools specifically optimized for LCP extraction.
