What did you think of our guide to free Kindle DRM removal Did it give you a clear idea of how to remove DRM for Kindle books, or does the process seem too convoluted and cumbersome Is there another piece of software you like that supports removing DRM from Kindle books Let us know in the comments below. Thank you for reading.
Was able to have it work for my small selection of books, I was using latest Calibre 6.8, and DeDRM 7.2.1The key for me is I needed to do as Calibre suggested, download the books from amazon website for usb transfer, then was able to decrypt those[azw3 & azw files), was not able to decrypt .kfx I pulled directly from my device directly (Huge size difference 5090 KB vs 774kb).Very nice to free up my purchases and port over to my nook, thankyou all for the continuous feedback or I would have given up.
calibre comes with a handy web server to host your library. In just a few moments you can safely share all (or just some) of your e-books with anyone you choose or access them yourself from anywhere, using any device you like. With the server, you can read the books in your calibre library on any phone/tablet using just a browser. It even works offline.
For the e-book nerds amongst you, calibre has a built-in editor that allows you to edit e-books in the most popular e-book formats, EPUB and Kindle. The editor has many sophisticated features to make editing the innards of e-books as easy and efficient as possible.
calibre has more than 3 million active installs and lots of fans! You will never have to wait to solve any issue you might encounter: you can use the extensive help resources, or just ask members of the calibre forum.
calibre is created by book lovers, for book lovers. Hundreds of motivated volunteers develop calibre and deliver updates on a regular basis. Most issues are resolved in a week. With every update, we fix bugs, add new features and make calibre more compatible, faster and easier.
calibre started life on 31 October, 2006, soon after the release of the SONY PRS-500, the first e-ink based reader to be sold commercially in the US. At the time, I was a graduate student, with a lot of time on my hands. The PRS-500 did not work at all with Linux, my operating system of choice, so I decided to reverse engineer the USB protocol that it used, to get it working on Linux. This was accomplished with the help of the fine folks over at mobileread.com and calibre was born, albeit named libprs500.
As my e-book collection grew, I realized that managing it was quickly becoming unwieldy, so I decided to write a graphical interface to libprs500 to make it easier. This became calibre, in its present form, as a comprehensive e-book management tool. libprs500 was renamed to calibre in mid-2008. The name calibre was chosen by my wife, Krittika. The libre in calibre stands for freedom, indicating that calibre is a free and open source product, modifiable by all. Nonetheless, calibre should be pronounced as cali-ber, not ca-libre.
Today calibre is a vibrant open-source community with half a dozen developers and many, many testers and bug reporters. It is used in over 200 countries and has been translated into a dozen different languages by volunteers. calibre has become a comprehensive tool for the management of digital texts, allowing you to do whatever you could possibly imagine with your e-book library. Reading is very important to me and one of my goals has always been to prevent either the fragmentation or the monopolization of the e-book market by entities that care solely for short-term goals. As the calibre community continues to grow, driven by book lovers, for book lovers, hopefully it will always present an alternative for people that love to read e-books and want to be in control of their own digital libraries.
The best places to ask for help with calibre are the very active calibre forum at mobileread.com, where there are a number of friendly and knowledgeable long time users/developers of calibre. In addition, there is the calibre Facebook fan page and #calibreforum on Twitter.
If you discover a problem with calibre or would like to request a new feature, the best place to do it is via the calibre Bug tracker. Be aware that calibre is developed by volunteers, which means that your bug report/feature request may or may not get attention, so if you are looking for help, the best place is the forum linked to above.
calibre is an open source application that uses a large number of other open source libraries and is developed on Linux, an open source platform, and as such, it has benefited from the work of large numbers of people, some of whom are listed below. I've tried to be as exhaustive as possible, but, if I have omitted your contribution, please let me know.
\\tE-book reader: The software comes with a basic e-book reader that supports fullscreen mode for distraction-free reading and that lets you choose your preferred method of pagination and gives you the ability to bookmark pages. Unfortunately, there is no way to annotate, highlight, or augment the book's contents short of editing the book itself.

Calibre (/ˈkælɪbər/, stylised calibre) is a cross-platform free and open-source suite of e-book software. Calibre supports organizing existing e-books into virtual libraries, displaying, editing, creating and converting e-books, as well as syncing e-books with a variety of e-readers. Editing books is supported for EPUB and AZW3 formats. Books in other formats like MOBI must first be converted to those formats, if they are to be edited.
On 31 October 2006, when Sony introduced its PRS-500 e-reader, Kovid Goyal started developing libprs500, aiming mainly to enable use of the PRS-500 formats on Linux. With support from the MobileRead forums, Goyal reverse-engineered the proprietary Broad Band eBook (BBeB) file format. In 2008, the program, for which a graphical user interface was developed, was renamed \"calibre\", displayed in all lowercase.
Calibre allows users to sort and group e-books by metadata fields. Metadata can be pulled from many different sources, e.g., ISBNdb.com; online booksellers; and providers of free e-books and periodicals in the US and elsewhere, such as the Internet Archive, Munsey's Magazine, and Project Gutenberg; and social networking sites for readers, such as Goodreads and LibraryThing. It is possible to search the Calibre library by various fields, such as author, title, or keyword; however as of 2020[update], full-text search has not yet been implemented.
E-books can be imported into the Calibre library, either by sideloading files manually or by wirelessly syncing an e-book reading device with the cloud storage service in which the Calibre library is backed up, or with the computer on which Calibre resides. Also, online content can be harvested and converted to e-books. This conversion is facilitated by so-called recipes, short programs written in a Python-based domain-specific language. E-books can then be exported to all supported reading devices via USB, Calibre's integrated mail server, or wirelessly. Mailing e-books enables, for example, sending personal documents to the Amazon Kindle family of e-readers and tablet computers.
This document will refer mainly to the conversion settings as found in theconversion dialog, pictured below. All these settings are also available viacommand line interface to conversion, documented at ebook-convert. Incalibre, you can obtain help on any individual setting by holding your mouse overit, a tooltip will appear describing the setting.
The transforms that act on the XHTML output are where all the work happens. There are varioustransforms, for example, to insert book metadata as a page at the start of the book,to detect chapter headings and automatically create a Table of Contents, to proportionallyadjust font sizes, et cetera. It is important to remember that all the transforms act on theXHTML output by the Input plugin, not on the input file itself. So, for example, if you ask calibreto convert an RTF file to EPUB, it will first be converted to XHTML internally,the various transforms will be applied to the XHTML and then the Output plugin willcreate the EPUB file, automatically generating all metadata, Table of Contents, et cetera.
You can see this process in action by using the debug option . Just specify the path toa folder for the debug output. During conversion, calibre will place the XHTML generated bythe various stages of the conversion pipeline in different sub-folders.The four sub-folders are:
If you want to edit the input document a little before having calibre convert it, the best thing todo is edit the files in the input sub-folder, then zip it up, and use the ZIP file as theinput format for subsequent conversions. To do this use the Edit meta information dialogto add the ZIP file as a format for the book and then, in the top left corner of the conversion dialog,select ZIP as the input format.
One of the nicest features of the e-reading experience is the ability to easily adjust font sizes tosuit individual needs and lighting conditions. calibre has sophisticated algorithms to ensure thatall the books it outputs have a consistent font sizes
