It took me a few years of iterative exploration to figure this all out to my own criteria ( it should not be so hard ), and in the process, I figured out how to get ebooks free from local libraries - there's no problem so big it can't be run from. so don't update, and or only try to bypass DRM on a PC/Mac AFTER installing earlier version of Kindle for PC/Mac, and AFTER re-downloading our ebooks, which will then arrive as the stable original AZ3 format.

Note, with random changes in DRM, static DRM-bypassing algorithms probably will fail on Kindle for PC/Mac version 1.25 or newer or with Kindle firmware 5.10.2 or newer. Reinstall Epubor Ultimate Ebook Converter AND install Amazon Kindle for PC/Mac v1.24/v1.23 ( which Epubor re-provides from Amazon archives over at, and THEN set Kindle for PC/Mac to NOT to update, and THEN re-download our ebooks, and we're good to go.Īllowing Amazon to auto-update our Kindle for PC is like letting Microsoft auto-update our Windows - it's our computer, not theirs, so take back control. Once we initiate the work-around, everything goes smashingly smoothly, untethering us from Amazon's clutches.

Īmazon likes playing with their latest KFX file formats, it's their proprietary non-standard, they change it on a whim, so avoid it.Įpubor provides copious instructions and resources showing us how to accomplish the task of bypassing KFX. To, who balked at re-downloading KFX ebooks to their PC/Mac as AZ3 ebooks in order to bypass DRM and export / convert our Amazon ebooks.
