Formally I was okay with buying all my books through Amazon because I could convert them with Calibre should I ever want to read them on a non-kindle device. But my understanding is that it is no longer possible do to changes implemented by Amazon. Just caught the first episode of the Strongest Rearguard and was thinking about purchasing the first volume. Would prefer Amazon still because of credits and gift cards, but considering another source in case I ever get a non-kindle device.

Thanks for your help. Hope you had a great weekend.

Hi, so I was trying to download a recent fanfic I enjoyed onto my Calibre library, but when I did, I received this error "HTTP Error in FFF '403 Client Error: , and the comment that the URL for the fic is forbidden, if anyone has any idea what is happening and if you know anyway to fix it, I would greatly appreciate it, thank you.

Solved - needed to download a DeACSM, and then not open the file before transferring it to Calibre. Opening the file marked it as already being engaged with another device somehow, and stopped the plugin from working.

To clarify: I'm not trying to steal books. Amazon released a new update intentionally bricking all older kindles, meaning I'm now unable to transfer borrowed books from Libby to my device even though it still operates perfectly. This workaround is the only way I can continue reading e-books on the kindle. The books are still automatically returned back to the library after the borrowing period, and I delete them off the device when I'm done reading.

• My decade-old Kindle is affected by Amazon's bricking of older Kindle devices
• I successfully installed Calibre and DeDRM and transferred book from Libby back in May
• I am trying the same process now and it is not working.
• My kindle has been in airplane mode the whole time and has not been updated.

My process:

• Borrow a book from Libby, 'read as Epub'
• This exports it as ACSM. I transfer this to my computer
• Open Calibre, ensure DeDRM is active, 'Add books'
• In Calibre, 'Title' = the book's file name. 'Author' is Unknown. 'Size (MB)' is '<0.1'.
• 'Convert books': I receive the error Could not convert the book because no supported source format was found

I've tried:

• Updating Calibre (version 9.11)
• Removing and re-installing DeDRM plugin
• Converting individually and bulk
• Configuring the e-ink DeDRM setting to add my Kindle's serial number, per the DeDRM read-me

I can't figure out what's wrong. I did this in May with no problems. Did something update? Am I missing a step? Please help.

Where do you change how the book is titled on download? Most readers are fine but some display the number (since it's titled ###.epub) instead of the metadata.

Just as the title says. I am planning on using my Kobo Libra Colour from now on. I enjoy reading books on it a lot more than my iPhone or my Kindle Basic. My Kindle is always so buggy.

I have about 90 books on my Kindle.

Hi all,

I read someones post months ago about how they managed their data for re-reading books. I cannot find the post now so asking the community :)

My issue is that I have a fic I read in 2020, I downloaded this fic and at the time, populated the Date KOReader Finished column with the 2020 date. I read it again recently and KOReader of course has not re-written the date (phew) but it didnt store the new date anywhere either.

Has anyone got a method of store re-read dates while keeping the original read date as well?

• New custom column?
• Multiple dates in one field with comma separation (I think this is what the post I read did)?
• How can it be automated?

Any tips and suggestions welcome!

I'm adding an EPUB downloaded with FanFicFare onto my XTEINK X4 device, but every paragraph starts on a new page. A chapter that should be around 30 pages ends up being almost 200 pages. There is a huge page break between each paragraph. 

I also tried converting the EPUB to EPUB again in Calibre and checked "Remove spacing between paragraphs," but it didn't help. I enabled Structure Detection and added / to the Detect chapters field as well, but that didn't change anything either.

The same original EPUB displays perfectly on my Kobo, so I'm not sure what went wrong.

Has anyone run into this before or know how to fix it? Thanks!

Been searching for the best epub book reader and many are good but none were to my liking. So I built my own and to me it is perfect. I would like to present and share with you Codexa.

Open source, light on system resources but very powerful with features. OPDS browser with folder sync. KOReader KOSync protocol support. StarDict dictionaries support. Epub and comics, multi language UI and multi-user. Custom epub parsing library for full control over navigation and many many more.

Full documentation also available with other feature lists and usage guide. Works in any browser, modern or old (old Android devices) as PWA installation or if you need hardward volume buttons also as standalone APK for Android phones.

My whole family uses it to read books on different devices (mobile phone Android/iOS, InkPalm Plus reader, Boox Palma 2, desktop browsers, ...) and I hope many other will find it useful as we do. All my books are in BookOrbit and accessed by using OPDS and also syncing progress to it for other devices (Xteink X4).

Some screenshots:

Library

Desktop reader

Mobile reader

For more screenshots check Github page: https://github.com/thehijacker/codexa/ or documentation pages https://thehijacker.github.io/codexa/

I use it in evening on my Palma 2 to read and when I can also on my desktop browser (Chrome). My son reads on InkPalm Plus and wife on Boox Go 7. During day I am reading on Xteink X4/X3 and when I am done sync progress to pick up in evening on Palma 2. Just perfect combination.

If anyone decides to use it I kindly ask for comments and suggestions how to improve it further. It will be forever free, open-source and developed primarly for my own personal project but it turned out so well that I wish to share it with others. Enjoy!

I am wanting to use my ereader to annotate more (maybe get a scribe soon if i like it enough to see if it compares to book annotating which i prefer) but I would like a way to quickly view them and where I could either have cloud or local backup methods periodically to ensure I don't lose my annotations. How do you organize your annotations? I use my home pc to manage my library on calibre and use KoReader on my Kindle PW5 so I am open to both calibre and/or koreader plug-ins or patches. something with an easy learning curve or none at all preferred <3

Amazon's May deadline has come and gone, and I'm beginning to get nervous. The archive that I have built over the last 15 years is the only non-DRM copy of my library that I know exists. I plan to back it up to DVDs, but I'm starting to worry about data integrity.

Historically, I would have left this to the cloud, but the experience with Amazon is really souring me on the idea of depending on absolutely anybody else.

Do you guys have any ideas for long-term integrity of our book libraries?

Hi everyone! I have this problem where everytime I upload a book through Calibre, my device works fine at first but after a minute it freezes, and I have to restart it to fix it. I tried uploading them the basic way (through drag and drop directly from my computer storage) and this problem doesnt happen. Has anyone else had this problem? Or any idea of how can I fix it? I tried searching through past posts but couldnt find anyone with the same problem, I would really appreciate the help!

For context, I have a Kobo Clara BW, and use Calibre with the Kobo Utilities and Kobo Metadata plugins.

Hey guys I am trying to convert Science magazine PDFs to ePUB and the layout comes out completely broken.

I wonder if this is a common problem for any magazines and there is some script or guidelines for that? thank you

I just found out about Amazon’s recent… ~~fuckery~~ nonsense with shutting down support for older kindles and the kindle for pc app as of a few days ago.

Problem is, I just found our old kindle paperwhite. I would like to buy a kobo and transfer my amazon purchases (about 250 books) over. But I don’t have anything downloaded to my pc, which is running windows 10. I refuse to download windows 11 to download the new kindle app but apparently you can’t strip DRM from books with the new app anyway?

Has anyone managed to figure out how to get around the ~~bullshit~~ nonsense so I can do what I want with the stuff that I bought?

Edit: THANK YOU SO MUCH to everyone who commented. I’m well on my way to getting all my books converted and stored on an external hard drive. 🧡

Hiya, so I've learned a lot about using Calibre and all in the past two or so days, but I can not for the life of me figure out the best way to get audiobooks worked into my Calibre Library. I don't know if it was ever possible to get amazon audiobooks into the Calibre library, but was it and perhaps is it still somehow? If not through there, I don't have many so I wouldn't mind restarting somewhere else like maybe Audiobookshelf, assuming I have that right?

Any pointers/guidance here would be great as I want to be able to listen to more books but as always not have to worry as much about them getting pulled or relying on some subscription or anything, thanks.

I could give an introduction about ownership of digital content and why it is important to have your own books and be able to read them on the device of your choice. However, I won't do it in this post. I'll just show you how to remove DRM from Kindle books in 2026.

I don't encourage piracy and the distribution of copyrighted material. You should use this tutorial only to read your books on other devices/mediums.

Prerequisites

This method requires a jailbroken Kindle. If you don't have a jailbroken Kindle device, this tutorial won't work.

If you haven't jailbroken your Kindle yet, follow the official guide at the Kindle Modding website.

Step 1 - Connect your Kindle to your computer

Connect your Kindle to your computer using the USB cable.

Step 2 - Download the DeDRM Kual Extension and Calibre Plugin

Go to the GitHub repository of the DeDRM plugin and download the file "kfxdedrm_kual.zip" from GitHub releases.

For the Calibre Plugin, search the same GitHub release page and download the DeDRM_tools.zip file. The version I have installed in this tutorial is 10.0.24, but I recommend always downloading the latest.

Step 3 - Install the DeDRM Kual Extension

Unzip the file "kfxdedrm_kual.zip" and copy the folder "kfxdedrm" into the folder "extensions" in your Kindle's root directory.

Step 4 - DeDRM your books

Disconnect your Kindle from your computer and open KUAL on your Kindle. Expand the program "DeDRM KFX files". Inside, you'll see a few options; select "Dedrm all KFX". It will scan all your Amazon books in the Kindle, and it might take a few minutes depending on the number of books you have.

While the plugin is scanning your books, proceed to step 5.

Wait until you see the message "DeDRM all done." before proceeding to Step 6.

DeDRM Extension

DeDRM all done message

Step 5 - Install the DeDRM Plugin in Calibre

The Calibre version I have installed for this tutorial is 8.10.0. You can find this specific version for download here: download Calibre. It might work with newer or older versions, but I haven't tested them.

Step 5.1 - Install the KFX Input Plugin

Go to Preferences -> Preferences -> Plugins -> Get New Plugins and search for the plugin 'KFX Input'. Install it. (don't restart Calibre yet)

KFX Input Plugin

Step 5.2 - Install the DRM Calibre Plugin

There are many tutorials on the internet on how to install this plugin, so I won't repeat them here. It is a very straightforward process. I recommend following this tutorial, and you can use the file downloaded from Step 2.

Restart Calibre after the installation of both plugins.

Step 6 - Add your books to Calibre

Connect your Kindle back to your computer, then open the folder "dedrm" in your Kindle's root directory. You should see all the books you have on your Kindle inside this folder with the "kfx-zip" extension. Select all the files and drag them into Calibre's interface.

Now you have all your books in Calibre, and you can do whatever you want with them.

Book import in Calibre

Step 7 - Convert your books to EPUB

Select all of your imported books and click on the bulk convert button. It will open a popup window, and on the top right corner, you will see the output format. Select "EPUB" from the dropdown menu.

Then hit "Ok" and wait for the conversion to finish. You should see the progress in the bottom right corner of Calibre.

Once the process is finished, select all books again, expand the "Save to disk" button, and choose "Save single format to disk..."

Now you have all your books in EPUB format, and you can do whatever you want with them.

Export book to EPUB

Save EPUB to disk

Local folder with EPUB

Hallo, so I’d say I’m still newer to e-readers as a whole and have somewhat followed the events of amazon making things much harder, if not impossible, to use current tools to move books to Calibre. From y’all’s experience, is it likely that someone will be able to update DeDRM or create another tool to get around these new updates?

I’ve also seen other’s post about asking about switching to Kobo, which I am also considering but I want to ask a question I haven’t seen yet. How likely is Kobo to follow Amazon’s path and create stricter DRM programs and all that to cut down the ability to offload books?

I have a Kindle Paperwhite and sideload my books using Calibre. On Calibre, my books have metadata like description, genre, etc. but I cannot view it on Kindle. That makes browsing the library on Kindle useless, but I'm not always near my computer. I'm wondering if there is a way to view the metadata of my Calibre library from my phone, or if anyone knows a way to have the Calibre metadata like description appear somewhere on the Kindle Paperwhite (within the book or some setting I don't know about)? Might just be a limitation of my eReader but figured I would ask. Thank you

I know Calibre automatically sorts authors by last name is there a way that I can force it to reverse that and have them sorted by FN, LN? I tried something the the tweaks section of preferences but it didn’t seem to work because just today I uploaded a bunch of books by Maria Frankland and it defaulted them to Frankland, Maria. So I had to update all of the metadata for said author.
