And unfortunately I don't think the DRM for the latest format (KFX) has been cracked yet. The best anybody can do is work around it by getting Amazon to send you the book in an older Kindle format but then you lose all the nice things that you get with KFX.

What do you get with KFX? It's hard for me to imagine any goodies I'd rather have than a file that I own and can read at my leisure.


One really nice feature you get is that if Amazon decides they want to delete the book from your kindle they can. It's a nice feature for Amazon and the publishers love it as well.


The improvements are listed here:

The writing is on the wall though - DRM is getting better and the easy to crack formats will probably fade away soon.

The solution isn't technical (ie better cracks), it's legislative. Books are special and most e-books shouldn't be DRM'd. Purchasers of ebooks should have the right to resell, to gift, to bequeath, to trade, and do all the other things that have been part of book culture for the past few hundred years.


Justification is much better on kfx


I haven't tested it:

That's basically a repackaging of the Apprentice Alf DRM tools.


April 2018: As of version 6.6.0, Apprentice Alf's DRM removal tools support Amazon's newer .kfx file format. You'll also need to install the KFX conversion plugin(link is external) to import your .kfx files into Calibre.

The GitHub repo for the DRM removal tools is here:

https://github.com/apprenticeharper/DeDRM_tools

The README says this:

> Note that DRM can only be removed from KFX format files downloaded with Kindle for PC/Mac 1.26 or earlier. Amazon changes the DRM for KFX files in Kindle for PC/Mac 1.27 and later.

KFX is different from older versions in that the file is tailored to the device it is downloaded on. If you download with the Kindle for PC, the file is optimized for your big, high resolution screen and isn't going to be great on an eink device.

There are no cracks that work with the KFX files extracted from the Kindle reader.
