It converts very quickly depending on the length of the book. You can have an ebook converted in as little as 5 seconds. This is such a useful function especially for people who like reading in just one particular ebook reader. For example, books are cheaper in ePub and you love reading in MOBI, you can still go ahead and purchase this ePub version, get on your device where Calibre runs and simply convert the book to any format of your choice which in this case would be the MOBI format.

 You can also edit the name and cover art, which is a nice feature for people that download books from torrent sites and very creative people. A lot of times the books downloaded from torrent sites have long titles because it might contain the uploaders name or date uploaded and so forth, calibre helps you edit to cumbersome information into what the title of the book really is or what you want it called on any of your devices. It’s also common for torrent sites not to have a books cover art, you can actually change all that with Calibre using the 'edit cover' are feature. There is a feature that will help you search and download the actual cover art from sites, such as Amazon, Google, and so on. You can even delete books from any of your other devices straight from Calibre. 

You can further download the metadata of a book. For example, if the book you are editing does not have a title, name, rating, and so on, Calibre will help you to search for all this information on sites like Google, Amazon, and the likes, download this information, and save it for later. You can also easily change important details on an ebook with Calibre. The convenience this software offers in terms of syncing your ebooks with any of your devices is next to none.

With the 'heuristic processing' feature, Calibre can scan and search through your books for repeated patterns and fix it.
