Ignore all the options for now and click “OK”. Just select the book you want to convert then click the “Convert books” button. When first running calibre, the Welcome wizard starts and will set up calibre for your reader device. In order to do that you’ll have to convert the book to a format your reader understands. Once you’ve admired the list of books you just added to your heart’s content, you’ll probably want to read one. Once you’ve added the books, they will show up in the main view looking something like this: Drag and drop a few e-book files into calibre, or click the “Add books” button and browse for the e-books you want to work with. What do you do now? Before calibre can do anything with your e-books, it first has to know about them. It is cross platform, running on Linux, Windows and macOS. It can download newspapers and convert them into e-books for convenient reading.

It can go out to the Internet and fetch metadata for your books. It can also talk to many e-book reader devices.

It can view, convert and catalog e-books in most of the major e-book formats.
