The following is a summary of the status as of April 26, 2026, based on various posts in this thread:

1. In general, books can no longer be downloaded to a computer from the Amazon website.
a. However, if a publisher so elects, certain books can be downloaded as epubs or pdfs (the choice is made by Amazon)

i. The pdfs are generally not considered to be very good for complex books.

2. Amazon has implemented a new DRM scheme--referred to in this message as "Hidden Key" DRM. Hidden Key DRM places the decryption key in a location that is intended to be inaccessible to users.

a. Kindle Devices

i. Firmware for "Newer" Devices that are still receiving updates has been updated to use Hidden Key DRM
ii. Some older Devices contain a backdoor through which Amazon is also implementing Hidden Key DRM

I. There is some indication that for these devices, the implementation disappears when the device is reset and is re-downloaded when you attempt to download a book. One user was able to prevent the re-implementation (at least temporarily) by filling the Kindle memory to a number that doesn't leave room for the implementation file.

iii. Older Kindle devises (PW1 and earlier) continue to be usable for DRM removal under standard procedures, but only until May 20, 2026
I. As of May 20, 2026, these devices will cease to be able to access the Amazon ebook system. If one of these is factory reset, it can not be re-registered.

b. Kindle for Android

i. Modern versions of Kindle for Android use a version of Hidden Key DRM that can not be broken for unrooted devices. I have not kept track of the status of Kindle for Android on rooted devices

.

c. Kindle for Mac

i. Dead.

d. Kindle for PC

i. Current versions of Kindle for PC uses Hidden Key DRM but the location of the key is accessible for some of this. A fairly complex method exists for decrypting ebooks downloaded to certain versions of Kindle for PC (search for "SATS" method). Commercial implementations of this method vastly simplify the process. (I have used Epubor successfully.)
ii. However, Kindle for PC will be retired on June 20, 2026 and a new version, solely for Windows 11, will become available. It is anticipated that the Window 11 version store the key in a secure location that can not be accessed without disabling some important security features of Windows 11.

I. There is no mention of a version of Kindle for PC to older PCs.
II. The announcement does not explicitly say that the existing versions of Kindle for PC will stop working after June 20, but it is likely that Amazon will, in fact cut off these versions shortly afterwards.

Let's get back to posting links to where detailed help with DRM should take place. Thank you.

Amazon has made some changes to how books can be downloaded. This affects the removal of DRM from these so they can be backed up and sideloaded onto other devices.

For current methods for downloading and removing DRM from Kindle ebooks see

the first post in this thread in the calibre forum

Download and Transfer stopping after 26th February 2025
Amazon have announced that the ability to download Kindle books from their website will go away after 26th February 2025.

If you have lots to download, and are on Amazon.com or Amazon.o.uk, the script here on github will allow you to bulk download all your ebooks.

It is a python script, so you will need to have Python 3 installed, along with three other packages (given in the documentation at github).

Other restrictions
Some books have additional restrictions and cannot be downloaded & transferred. The Bluestacks/Android app will not work either. The two main categories of these seem to be textbooks and books published for the Indian market.

If you're having trouble, including the ASIN (a string of numbers and letters, found in the URL and usually starting with 'B0') will help us determine whether the book has additional restrictions.

Here are some options if you absolutely must read that book and can't get it from Amazon:

Check if the books are available on other websites that offer DRM-free or more easily-removed ADE (Adobe Digital Editions) DRM:
- eBooks.com
- Kobo
- Google Play
- Smashwords
- Book Republic, Italian.
- Baen, for science fiction & fantasy.
Overdrive allows borrowing books; if your local library's offerings are short, many libraries offer non-resident cards.
However, if you see a self-published/indie author's books offered on Kindle Unlimited, there's a good chance that they're using the KDP Select program, which offers higher royalties and listing on Kindle Unlimited in exchange for exclusivity.
If you decide to buy a Kindle to take advantage of download to Kindle make sure you get an older e-Ink one! Not a Kindle Fire.

However, some advice:

[...]I recommend obtaining a model that allows books to be downloaded to the device directly from Amazon over WiFi in KF8 format which can be accessed via USB.

I would avoid the 1st and 2nd generation Kindles and the DX. They only support the old MOBI format and may no longer be able to connect to Amazon.

The Kindle Keyboard (3rd gen), Kindle Touch (4th gen), and Kindle (4th & 5th gen) are workable. However they may require manually installed firmware updates to be usable. And as older models they are more likely to be cut off from service in the future.

The Paperwhite 1 (5th gen) is the most desirable option in my opinion. It is the newest model that does not support KFX format.

I would avoid newer models than that. Most of them support KFX out of the box that cannot be disabled. Some models that didn't can be reverted to older firmware that does not support KFX, but that requires jail breaking which is more difficult to set up and risks bricking the device.

For image-heavy books, you would want to use jhowell's modified version of the AZW6 Image Merge plugin for Calibre. Note images will be in greyscale.

Original version of post:

Spoiler:

Amazon has made some changes that newly-published books can't be downloaded on earlier versions of Kindle for PC. This makes it very difficult (maybe impossible?) to strip the DRM from them without access to an e-Ink Kindle. While older books appear to be unaffected yet, I would not be surprised if that changed soon.

What are your thoughts on this?

Going to quote some posts from other threads:

I have updated the first post in this thread to reflect this change.

also, how is that affected, if at all, by owning various vintages of eink kindle?. I still have a paperwhite 3 (7th gen)- is that old enough to not support kfx? NO, says google:

[People also ask
Does Kindle Paperwhite support KFX?
Kindle KFX format is the successor to the azw3 format and released with the Kindle Paperwhite 3. ]

so the select transfer via USB to get azw trick will need a paperwhite 2 or older ?

I guess I need to find a free book published yesterday to test my options

This change has no effect on e-ink Kindle owners, at least so far.

My worry is that Amazon might stop allowing Download and Transfer via USB for books published after a certain date. That feature is already unavailable for certain categories of books and for free samples. That change would leave only extracting books from the Kindle's storage using USB, which only works for Kindles running old firmware. Hopefully Amazon is reluctant to further disable downloads since Kindle owners who do not have Wi-Fi would complain.

It depends on the firmware version installed. If is has firmware prior to version 5.6.5 it does not support KFX. If the firmware is prior to 5.12.2 it supports KFX but DRM removal is possible. Newer than that and you may be out of luck if Download and Transfer goes away.

Oh well, I've enough of a back-log to last me a lifetime, I may even end up thanking Amazon to help me stop buying every ebook I see on a deal

(who do I kid? I've already bought 5 ebooks on the kobo store since the start of the year

My list of unread books is hundreds of kilometers long anyway, so I can live without Amazon exclusives.

So Amazon have gotten away with new rules without much outcry.
But if Amazon imposed kfx only on all new fiction, then kindles older than paperwhite 3 would not work with those books.
Are there any figures for how many book buyers still rely on such older devices and would be disenfranchised?
I am thinking the only way they could do that is by offering a very cheap upgrade option for those people which 2ould be costly. Far more costly than what they lose due to ebook piracy ?

I don't think any kindle generation has been made obsolete yet ?

I think Amazon may be switching to KFX only delivery on devices/software that can handle KFX. I hope I'm wrong.

But if they offer a upgrade bribe only to owners of pw2 or older, that would piss off pw3 owners: And that would be a larger number .

the trade in, trade up offer for my pw3 is an unattractive £20, with no % discount on a newer model but I can't see the offers for models I don't own.
