Epubor Ultimate 

Epubor Ultimate provides you with a simple and convenient solution to read your favorite e-books on various devices. It supports converting the e-books purchased from most retailers and offers to remove their DRM protection, so you can enjoy a seamless reading experience.

The utility comes with a clean and intuitive interface, which makes using the program a hassle-free task. Importing the files you wish to optimize for your device is done easily, either by browsing for documents from within the app or by dragging and dropping them onto the conversion panel. Choosing the output format isn't difficult, as the list of conversion profiles is organized both by file type and by device name. However, if your e-reader is connected to the computer, the tool detects automatically the device, displays the existing books, and waits for you to drag the desired documents into the main interface for automatic conversion. Furthermore, you have the ability to edit the e-book metadata if the document needs title, author, or date corrections. Replacing the book's cover is also supported.

To conclude, Epubor Ultimate is a smart e-book converter that allows you to optimize electronic documents for convenient reading on personal devices. Removing the DRM protection is guaranteed - if the embedded engine can't help you, you can always ask the customer service to fix the problem.
