How I bypassed Amazon's Kindle web DRM

AdmiralAsshat•1h ago
I don't suppose this is going to work well with their comics/graphic novels, will it?

I stopped buying ebooks from Amazon some time ago and switched completely to Kobo (and their much-more-easily-defeated DRM), but Amazon's acquisition of Comixology means they've still got by far the best collection of digital comics on the market.

BolexNOLA•1h ago
I’m sure you already know this but I’ve actually had a lot of success getting comics on hoopla with my library card. Obviously this completely depends on your local library but if you haven’t it’s worth looking in to! Has what I want a solid 35% of the time. Not the newest releases but I’ve gotten stuff that’s only 6 to 12 months old without much issue
AdmiralAsshat•1h ago
Not my use-case. I have roughly 250 legitimately purchased graphic novels and manga purchased from Amazon over the years that I'd want to backup.

I have about half of them already ripped, from an earlier time when the Kindle4PC application was easier to crack. But I still grab new comics from time to time.

boldlybold•57m ago
Comics need a full "image" for the page, so this is unlikely to work. Can you inspect the requests and see what you get?

Or to the author: what happens to images in the ebook?

gruez•52m ago
If all you need is an image, can't you just use browser automation tools to screenshot each page? After all, much of the content is in images so it's not like you need it OCRed for accessibility purposes.
rs186•43m ago
If you can live with lower quality image. Most people probably will be ok with that though.

I personally have bought many fewer books over the last couple of years, from amazon, as they've made it harder and harder to, you know, read the books I've paid for.

Pirating books is not hard. They're probably the smallest possible thing that people are interested in copying with the broadest variation in acceptable formats.

I know I'm screaming into the void, but if I'm paying real money why is the experience from piracy sites better?

Insanity•1h ago
Genuinely curious to hear why you think they make it harder and harder to read books? I've been using my Kindle daily since 2017. I read on both the Kindle device (Paperwhite and vanilla), the iPad and iPhone app, and occasionally the web reader.

I've never experienced issues with them that break the reading experience. The one issue I occasionally run into is that the book progress doesn't sync when I open the app and I have to click "sync now" which sometimes is blazingly fast and sometimes takes like a minute.

I can't imagine migrating away from Kindle now, it's probably one of my favourite devices and the Kindle is my favourite way to read.

cyberax•50m ago
Their devices get steadily worse. Kindle Oasis was the best device ever. It also had cellular connectivity so you could read it on a train, then put it in the backpack and switch to listening to the same book on your phone.

All seamlessly, because Kindle used the cellular network for reading progress. Really a magical experience.

Then they removed cellular and _buttons_ from the devices. And now their app is actively crashing on my Kindle when I try to use it to buy a book.

radley•38m ago
I've had decent success with a Kindle device, but when I try to use the Kindle app on my iPhone, which is rare now, it's almost always a hassle. Their iPhone app updates completely replace the app, so everything gets reset and books have to be downloaded again.

But the main problem is that they don't sync the "last read" bookmarks until you open a book. But since that book didn't have a bookmark, it's reset to the beginning and then synced, so my "last read" bookmark is now at the beginning.

wishfish•23m ago
The reading experience is fine on Kindle. Or at least it was the last time I used it. My main problem is how they've locked down the DRM. I was on Kindle for a very long time and didn't mind the DRM because it was easily breakable. Amazon was also helpful about helping you download the book file directly. The locks they had in place were essentially bathroom door locks. And they seemed chill about it.

That's all changed now. I'd love to know why it's changed. My first thought was publisher pressure. But Kobo hasn't implemented harsh measures. Just Amazon has.

At any rate, I'm now using Kobo for my reading. Easy to break DRM. And they don't assume the same level of control over Kobo ereaders the way Amazon does with Kindle. I have over a thousand ebooks. I'm able to tag books in Calibre, and those tags automatically show up as Collections on the Kobo. It's a simple thing, but Amazon never gave me such flexibility. Makes a huge difference for me.

It's also possible to alter Kobo's UI/UX with various plugins without the need to jailbreak. Kobo (the company) is perfectly happy to let you do whatever you want with your own device. That's such a breath of fresh air compared to how Kindle is locked down.

In general, if I don’t have to pay someone to produce something I can provide a better experience to my customers than those who do.

It’s why archive.is is so much better to read on than a news site.

Might as well ask “when I engage with GPL projects it’s so much worse of an experience than if I just bundle the code and distribute it without a license, why?” It’s often cheaper to not comply than to comply.

But my kindle has definitely been “good enough” for me with Libby.

sointeresting•1h ago
I bypassed it by buying a Kobo.
EA-3167•59m ago
I appreciate the author's work, and they're absolutely right about the Kindle app. I'm with you though, I don't want to fight tooth and nail with Amazon to have the ability to read a book without their lousy app, to back that book up, and otherwise legally and fairly use it. I don't want to reward Amazon for being aggressively anti-consumer by spending money on their site, at least not for this.
surgical_fire•57m ago
Likewise, but I went with Pocketbook.

I wish more people would understand that we empower those companies by using their products and services. Avoid when you can and they lose their power.

This is a great write-up in terms of content but stylistically it reads like the output of an RLHF'd LLM
ethmarks•33m ago
It's extra distracting because it doesn't even read like normal LLM prose, but it's close enough to feel off.

The frequent use of bold emphasis, lists, and subject-only rhetorical questions ("Those tiny m3,1 m1,6 m-4,-7 commands? They're micro-MoveTo operations.") are classic LLM-speak, but they're used in such a way that makes me doubt that OP actually used an LLM to write this. I think that OP's natural prose just happens to be stylistically pretty similar to that of an LLM.

It's kind of sad that what were once signs of high effort and dedication (e.g. em-dashes) are now signs of low effort and dishonesty, despite the fact that people still use them in human writing.

boldlybold•55m ago
This is a beautiful solution to a tedious problem that shouldn't exist in the first place! Great work.
harshreality•49m ago
I don't know what state it's in (haven't used it in years), but do apprenticealf's DeDRM tools, which has been forked to nodrm/DeDRM_tools, still handle kindle PC app downloads? Tinkering with old versions of the PC app might work even if the current version doesn't, and there's a registry hack to disable kfx downloading and get azw3 instead, which worked at some point... it's outlined in apprenticealf's DeDRM repo, at the wiki link provided at the top of the repo's README, in the short section saying it's no longer maintained.

That would provide a closer-to-original version of the ebook, rather than just a visually similar one.

That any of this is necessary at all is absurd. Hats off to anyone with the patience to bypass Amazon's DRM rather than giving up on the Amazon ebook ecosystem entirely.

ashton314•45m ago
The thing that killed the download -> crack DRM workflow is that Amazon removed the "download and transfer via USB" option. I haven't bought an ebook from Amazon since.

The only viable option would be to buy the book and then pirate a de-DRM'd copy.

Uvix•42m ago
It will handle downloads for older versions of the PC app, but the supported version won't download any books released after April 2025.

My main peeve with rendering in the Kindle app is that formula-type content (often even minor stuff like x²) is rendered as images that (a) are very low-resolution and (b) don’t invert in dark mode.

A second peeve is that in dark mode you can only have gray on black, not white on black.

harshreality•41m ago
Do the ebooks you're referring to use an image for the ² symbol, rather than css, unicode, or mathjax-generated mathml? A lot of old math books that have been converted from scans do that, for instance, because their OCR was okay at regular text but not good at superscripts, subscripts, or other mathematical symbols.
layer8•7m ago
They use an image in the Kindle version. I don’t know about other versions, but I assume the PDF version, if any, wouldn’t. These aren’t old books, they are recent nonfiction books from established publishers. They surely don’t use OCR to produce the Kindle version.
GauntletWizard•44m ago
At one point I did the same for a comic app which was getting the earliest releases of a manga I wanted to read; I still don't read Japanese but was the buyer for my translation circle. They had similar forms of obscure obfuscation; They scrambled the image into chunks, then you got a metadata that remapped it into a finished image. Raw, it looked like one of those slide puzzles.

Over the course of a couple years they updated their scrambling; First to randomize the size of the regions, then to make them triangular instead of rectangular. It was an interesting if tedious challenge to reverse engineer.

wkat4242•42m ago
Me too. When they removed the option to download books I liberated everything I had ever bought, moved to Kavita+koreader and will never buy a kindle book again.

I jailbroke both kindles. And use koreader on them which now supports progress sync with Kavita which is amazing! So I don't really lose functionality.

clumsysmurf•41m ago
I have the same problem with O'Reilly / Safari ... I don't enjoy using the apps and find they get in the way of the reading experience, plus it's a very expensive subscription. Initially, its hard to tell if rendering problems are just a bad conversion or if the text rendering engine is just buggy / borked.

But there were plenty of other bugs like bookshelf management getting corrupted.

Hell hath no fury like an engineer angered! This was such a good read and epitomizes hacking:

"Was it worth it? To read one book? No. To prove a point? Absolutely. To learn about SVG rendering, perceptual hashing, and font metrics? Probably yes."

chmod775•23m ago
For books only available through Amazon my workflow used to be buying it, downloading it with their desktop app, importing into Calibre, converting to epub and stripping DRM, then pushing it onto my Kobo.

They broke that a while ago by making their DRM even worse, so now I just pirate those books.

pmarreck•16m ago
Followed the same path.

semiquaver•10m ago
This is great work, but I’m not clear on why this qualifies as DRM at all. It sounds like the OP reverse engineered a protocol for rendering pages from a book to the web client. Sure, rotating the glyph ids every API call is annoying but it hardly qualifies as encryption or even obfuscation, just an extra mapping step the decoder needs to handle.

Sure seems like whoever at Amazon wrote this didn’t realize that it backdoors their DRM.
