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, Apprentice Alf, and Apprentice Harper. 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.
