Kindle for PC Update v1.19 Adds Support for KFX Format

A report has crossed my desk that Amazon has rolled out a new version of Kindle for PC,but I can't confirm that first hand.

JHowell reported over on MobileRead on Thursday that:

Starting with version 1.19, Kindle for PC will download books in KFX format and display them with enhanced typesetting.

The various files that make up the KFX format are all present, but named differently compared with an e-ink Kindle. Here is the same book after downloading to both platforms.

KFX is the newest version of the Kindle ebook format, and was first announced in the summer of 2015. It was first supported on the Kindle iPad app in 2015, and is only now coming to the Kindle for PC app. This format gave us improved typography and formatting, and also an extra layer of DRM which has so far proven uncrackable.

There are reports that Amazon has started pushing out v1.19 as an update. I don't have it yet, and in fact you can't download it manually.

But JHowell did point me to the new accessible Kindle app, which does feature the v1.19 update and KFX support. That app is in beta, so I won't be messing with it.

I am avoiding the app because of the KFX DRM,

Thanks, lemondrop, for the tip!

  1. Kindle for PC is the way I normally can get a KFK file converted to an AZW file for archiving with Calibre. If that is no longer going to be possible, then I will avoid the update…

  2. Once the new update becomes obligatory (this normally happens), it will no longer be possible to download a book in a non-KFX format unless you have a pre-PW2 Kindle. This means you will no longer be able to remove DRM from your books or convert them to other formats.

    • What if the ebook is DRM free? Will that be fine or is it that DRM free books will not be in the KFX format. Anyone can reply, I’m confused here.

  3. Good to know. I have an original PW. Didn’t realize KFX support was limited to PW2+.

    DRM-free books can be distributed in KFW format. All that the DRM-free requires is that every copy will be identical, not encrypted by destination.
