Welcome to Apprentice Alf’s blog
This blog is intended to help anyone looking for free and simple software for removing DRM from their Kindle ebooks, stripping DRM from their Adobe Digital Editions ebooks, getting rid of DRM from their Barnes and Noble ebooks, freeing their Kobo ebooks of DRM, deleting the DRM from their Sony eBooks, or decrypting their Fictionwise eReader ebooks.
If you want to find out more about ebooks, DRM and why you will probably want to remove the DRM from your ebooks, see this post: Ebook Formats, DRM and You — A Guide for the Perplexed
If you already know that you want to strip the DRM from your ebooks, you’ve found the right place.
To get started on removing DRM from your ebooks, just download the tools archive from one of the links below. Unzip the archive, and start reading.
The latest tools_v6.05.zip can be downloaded from
The latest plugin for Calibre can be downloaded from
- The download link is the grey button on the left under the file information.
- If you can see a checkbox labelled “Use our download manager and get recommended downloads”, uncheck it before downloading. Some users will not have the check box.
- Do not click on the advert on the right-hand side of the page, even if it says “DOWNLOAD NOW”.
- The download will be a .zip file. If your download is a .exe file do not run it, as you have downloaded the download manager. Make sure that the check box is unchecked
- No credit card or payment of any kind is required to download the tools.
- Datafilehost.com is marked as suspect by some virus checkers, which is rather obvious as anyone can upload anything to it. If you are worried about the integrity of the tools, listed below is the MD5 checksum.

Getting Help with the Tools
If you have any questions about the tools, ebooks and DRM, check my FAQs post Frequently Asked Questions about the DRM removal tools.
If you have any problems with the current tools, please ask for help in a comment on this post. If you are having a problem with an older version of the tools, please first update to the current version, and see if that solves your problem.
Before commenting here, please check the ReadMe file and the FAQs (see link above).
In any bug report or help request, please include
- which tool was used
- which OS you are using
- where the ebook file came from (device or folder)
- any error messages
- a log of the DRM-removal attempt (see the FAQs on how to get a log).
Please only use this application for gaining full access to your own ebooks for archiving/converson/convenience. De-drmed ebooks should not be uploaded to open servers, torrents, or other methods of mass distribution. No help will be given to people doing such things. Authors, retailers and publishers all need to make a living, so that they can continue to produce books for us to read. Don’t be a parasite.
Origin of the Tools
They have since been improved by many people, but mostly some_updates, DiapDealer and Apprentice Alf. While there are many sites that redistribute these tools, the most up-to-date versions of the tools are currently released here.
Anyone trying to sell you ebook DRM removal tools for Adobe Adept ePub and PDFs, Barnes & Noble ePubs, Kindle ebooks or eReader ebooks has probably just repackaged (an earlier) version of the tools available here.
