How to remove eBook DRM with Calibre

The eBook DRM puts lots of restrictions on legitimate users and forces users to view the ebook on a single device or app. It also controls your usage and doesn’t allow you to share the books with others. In simple words, DRM (Digital Rights Management) limits the number of devices on which you can read ebooks.

Vendors like Amazon, Apple, and others have their ebook DRM that would allow you to read the book using the device or app specific to the vendors. Most of us would want to read ebooks on multiple devices, and during such cases, the most viable way to overcome this limited usability is by removing the DRM from ebooks.
