ProsĮ-book converter: With Calibre you can take an e-book in one file format and convert it to another that is supported by your e-book reading device and, if you're not happy with the result, you can tweak the conversion settings and even manually edit the book's contents and formatting.
The only area where the software is lacking is its e-book reader it doesn't allow you to highlight or add notes to your books. An all-in-one solution for handling your e-books, Calibre does for electronic books just what iTunes does for music, allowing you to manage your digital book collection through an intuitive albeit overcrowded interface while offering excellent support for converting books to different formats and editing their metadata.
