As a last resort, some tools reconstruct the book by rendering each page and applying OCR. This is slow and lossy but works on any DRM. Some tools downgrade the eBook to an older DRM version (e

Digital Rights Management (DRM) is widely employed by eBook publishers (e.g., Amazon, Adobe, Apple) to restrict the copying, sharing, and format-shifting of purchased content. However, a parallel ecosystem of software tools (e.g., Calibre plugins, DeDRM, Epubor) has emerged to circumvent these protections.
