Calibre is a free and open-source ebook library management application that's packed full of useful features. For this DRM removal process, you'll need Calibre and apprenticealf's DRM removal plugins.
If you want to be able to send ebooks from Calibre straight to your device, fill in your associated emails on the next screen. For the purposes of the DRM removal process, you can skip this step. Finally, click Finish, and the app will boot.
After downloading and installing the app, you'll need to download all your books to your local machine. Once you've got them saved, just drag and drop them into the DRM removal software and click Convert. Simple and effective, but unfortunately, it's not a free way to get rid of DRM from EPUB files.
Anyone trying to sell you ebook DRM removal tools for Adobe Adept ePub and PDFs, Barnes & Noble ePubs, Kindle ebooks, Kobo ebooks, or eReader ebooks has probably just repackaged (an earlier) version of the tools available here.
The DRM removal plugin (DeDRM_plugin.zip) can be found in the tools archive linked from the most recent post in this blog. The DeDRM plugin can remove DRM from Kindle eBooks (but not rented Kindle ebooks, books downloaded to a Kindle Fire, Kindle for iOS or the Windows Store Kindle App), Barnes & Noble ePub ebooks (but not books downloaded to the Windows Store Nook App) , any ebooks using Adobe Digital Editions DRM (this includes ePubs from Kobo and Sony that are downloaded for Adobe Digital Editions), and the older Mobipocket and eReader ebooks. For other kinds of ebooks see the other posts in this blog.
The calibre developers are not involved in the development of the DRM removal plugin, and are not able to help with any DRM removal questions. If you have any difficulties following the instructions in this post, the calibre developers will not be able to help.
Most Amazon Kindle ebooks are Mobipocket format ebooks, or the new KF8 format. However, some are in a format known as Topaz. The Topaz format is only used by Amazon. A Topaz ebook is a collections of glyphs and their positions on each page tagged with some additional information from that page including OCRed text (Optical Character Recognition generated Text) to allow searching, and some additional layout information. Each page of a Topaz ebook is effectively a description of an image of that page. To convert a Topaz ebook to another format is not easy as there is not a one-to-one mapping between glyphs and characters/fonts. To account for this, two different formats are generated by the DRM removal software. The first is an html description built from the OCRtext and images stored in the Topaz file (HTMLZ). This format is easily reflowed but may suffer from typical OCRtext errors including typos, garbled text, missing italics, missing bolds, etc. The second format uses the glyph and position information to create an accurate scalable vector graphics (SVG) image of each page of the book that can be viewed in web browsers that support svg images (Safari, Firefox 4 or later, etc). Additional conversion software can be used to convert these SVG images to an image only PDF file. The DeDRM and Kindlebooks tools from this site provide both versions of the Topaz ebook so that the user can choose which one to use. The K4MobiDeDRM plugin only produces the html version of the ebook. The html version can be manually cleaned up and spell checked and then converted using Sigil/calibre to epubs, mobi ebooks, and etc.
All the DRM removal tools hosted here are almost entirely scripts of one kind or another: Python, Applescript or Windows Batch files. So they are inherently open source, and open to inspection by everyone who downloads them. The source for any compiled pieces are provided right inside the tools themselves.
