Starting in 2015, Amazon has developed a new format called KFX. This format adds advanced formatting options such as hyphens, ligatures, and improved word spacing.

Until recently there was no way to remove DRM or convert KFX eBooks to other format. The only way to crack this format was to downgrade the Kindle for PC to the version 1.17, download the old format ebook, and remove the DRM.

The good news is that Discoverysoft eBook Converter Ultimate can remove DRM on the latest version of the Kindle for PC / Mac, without downgrading to Kindle for PC version 1.17.
