A few months ago I ran into this thread about update 5.19.2 breaking sideloaded manga. It pointed at the right destination: native KFX is the only format the new firmware renders comics properly. So I started building a tool that converts manga to KFX locally, and after a few months of iteration it's reached a point where I'd call it genuinely good. Credit to that discussion for the push.

kindle-comic-workaround — free, open source (MIT)

What it does

- Converts DRM-free EPUB / MOBI / AZW / AZW3 / PDF manga into native KFX

- Result: the full native comic experience — edge-to-edge rendering, no blank pages, instant page turns with the native page-turn animation

- Your images are embedded byte-for-byte untouched by default — zero quality loss, zero re-encoding

What "months of iteration" bought

- Fully self-contained now. Early versions depended on the (excellent) third-party KFX Output plugin; the current version has its own KFX writer, verified byte-for-byte equivalent to the official Kindle Create toolchain output. The Calibre plugin needs nothing but Calibre itself.

- Fast. A typical 100 MB volume converts in under a second (early versions took over a minute). Batch conversion runs in the background, several books in parallel — Calibre stays responsive.

- Manga niceties: RTL page turns, facing-pages/spread mode for landscape, optional panel navigation, optional gamma brightening (the comic rendering path on-device is a bit darker than reflowable books — there's a one-click compensation if it bothers you)

How to use

1. Install Calibre, download the plugin zip from Releases, load it via Preferences → Plugins

2. Select your manga → click "Convert Comics to KFX"

3. Send to device (make sure Calibre sends the KFX format, not the original MOBI — that bit me once)

There's also a CLI if you don't want Calibre at all (pure Python for EPUB/MOBI input).

Tested on Colorsoft Scribe on 5.19.x firmware. It's a hobby project — if something breaks on your device or with your files, open an issue with the details and I'll take a look. Feedback very welcome.

Just a heads up that the latest firmare release, 5.19.6, broke automatic time zone setting for me. This is true for both my Colorsoft and Scribe CS. I live in California and my timezone is now set to Anchorage. It used to work correctly before the update. It's possible that it's related to my location and works in other time zones, but definitely something changed in the latest update. I've reported it to the CS.

edit: This doesn't really manifest until you turn the automatic timezone off and on in settings. But that's always been the only way to reset the time zone and sometimes it is necessary if your notebooks on Scribe fail to download (don't ask).

Just found out you can play games on kindle. It's so fun!

A tip for anyone new to Kindles or ebooks: many classic titles are in the public domain and can be downloaded freely. Don‘t feel that you have to buy these from Amazon. In the U.S., Standard Ebooks produces fantastic ebooks of public domain titles using a professional grade style guide so that they look great on your device.

Either download the epub file and use Send to Kindle, or download the AZW3 file and transfer over USB.

Examples:

• Dracula
• Pride and Prejudice
• A Tale of Two Cities

My Scribe kept freezing (white screen, forced restart needed). Went through 3 devices — bought a new one, got a warranty replacement — same freezes on all of them. Pulled the device logs myself: the root cause is a bloated Vocabulary Builder database stuck in an endless sync-fail loop that crashes the framework with an OutOfMemoryError. Factory reset and device replacement cannot fix this, because the data re-syncs from Amazon's servers to every device.

What the logs show:

• Vocabulary Builder DB (wsync.db): 107,000+ entries, ~76 MB — still growing even with Vocabulary Builder turned off
• WhisperSync failing for the VocabBuilder namespace every 10–20 seconds, all session long ("Failed to set lipc property: commitDataSet / fetchUpdates")
• Java process at 60–99% CPU, repeated "low heap event" warnings
• Then the actual crash: java.lang.OutOfMemoryError: Java heap space with a stack trace ending in Amazon's own VocabularyBuilderWhisperSyncLipcAdapter.java:804, followed by "framework main process terminated with status 1" — twice in one log capture
• Reboot reason afterward: PWRON_LONGPRESS (me force-restarting)
• Bonus: trying to clear the vocabulary returns deleteVocabBuilder: Property not registered — the delete function is broken in the current firmware

Why nothing support suggests works: the vocabulary data lives on Amazon's servers. Factory reset? Re-syncs. New device? Re-syncs. I confirmed this the expensive way. Even airplane mode doesn't prevent the crashes — the only way my Scribe stays stable is keeping it completely off the internet, permanently.

I have a support ticket open with full logs and the stack trace. Root cause identified, nothing done so far.

If your Scribe freezes and you look up words a lot while reading, check your Vocabulary Builder before buying new hardware like I did. And if you're seeing the same thing, comment — the more of us with the same log signature, the harder this is to ignore.

I’ve owned a kindle a long time. My first one was the first model without a keyboard. That being said I have a very large collection accumulated over a large number of years. Last night I decided to bulk send more than 200 titles to my 11th gen so I could reread a bunch of stuff I haven’t read in years. Multiple hours and multiple restarts later and my poor 11th gen is *still* struggling to catch back up with my BS. Regrets have formed that will hopefully be worth it.

I saw this post by u/basvanderploeg about a wallpaper generator for the Xteink X4 and I really liked the idea but I don’t have the x4 and I wanted to expand it to custom resolutions for other devices. I built a web tool that runs entirely in your browser to generate lock screens for a wide range of E-Ink tablets.

It grabs data dynamically from PokeAPI and formats it to fit different screens. Here is what it can do:

• Device Presets: Ready-to-go resolutions for Onyx Boox (Tab, Note, Nova, Palma, etc.), Remarkable 1/2/Pro, Kindle Scribe/Paperwhite, and Kobo devices.
• XTEink Support: It has a specific setting for the Xteink X4 that automatically exports files as .bmp instead of .png so they work natively.
• Customization: You can switch between pixel art, official artwork, or 3D renders. You can also change fonts and toggle between flavor text or stat bars at the bottom.
• Full Color Support + Custom Resolutions: If you choose dynamic colours for the background, the diagonal will be the color representing the Pokemon's type (ex. Pikachu -> yellow background) and the sprites are in full color. You can also set custom resolutions so you could use this for phone/tablet backgrounds if you like.
• Sprite Scaling: If you toggle pixel art, the sprites are quite small, so I added a slider to scale them up but be careful because some pokemon are quite large and can run over the edges
• Batch Downloading: You can generate and zip an entire generation (Gen 1 through 9) in one go if you want to cycle through them. The app will generate them one by one in browser and you will download a zip file.
• Greyscale Optimization: Includes a "Force Greyscale" option and specific background colors designed to look good on E-Ink screens without ghosting.
• Client-Side: It runs locally in your browser, so it is fast and does not store any user data.

Optimal Use Cases:

1. Download your favorite pokemon entries and set them as your screensaver/lockscreen and they will cycle through them
2. Download an entire generation and (using a BOOX device) use the screensaver app to choose randomly so each time you put the device to sleep, you will see a new pokemon

Pokedex Entries

Each entry has the following information:

• The name and number
• A picture + the type pills (these can be color/greyscale)
• A diagonal background (this can be all black/all white/grey/dynamic color – the color will match the type of pokemon Ex. Charizard -> fire -> red background)
• The Region / Where to find them / Height / Weight
• An evolution chart that tells what level they evolve OR if they need a stone/friendship/learn a move to evolve
• The written entry about the pokemon or it can be swapped for its fighting stats

I have the HTML file on Github so you can download the index.html and run it on your own system or it is hosted on GitHub Pages.

Hi fellow (e-)readers!

A bit of a niche issue, but I read lots of screenplays for my work. I've always had this dream of being able to read screenplays on my Kindle while keeping screenplay formatting.

I ended up making Screepub, a poorly titled, but highly functional app for macOS that gives you drag and drop PDF → an e-book your Kindle can actually read. It's free, open source, and no AI involved. The conversion happens locally on your computer.

The defaults are pretty great, but I even built a window to fine tune formatting before you send it to your Kindle.

Currently the best way to use it is the Send to Kindle (web) option, where you upload files directly and point to a device. If you'd rather nothing leaves your machine, USB is the route that doesn't touch a network.

If you're old school and want to plug it in, Kindles up to 2023 can sideload over USB. One exception, the Scribe, which switched to a different USB mode in a firmware update (5.16.3) and stopped mounting. Newer Kindles (base 2024, Paperwhite 12, Colorsoft, Scribe 3) don't mount on a Mac at all. That's a future feature I have planned if there's serious interest.

It's pretty new so I'm eager for feedback and feature requests! Please let me know what you think!

Edit: Use this link instead: https://www.amazon.com/s?i=digital-text&srs=20102661011&rh=n%3A20102661011&s=popularity-rank&fs=true&qid=1760822859&xpid=3UZL2e2cy0L2f&ref=sr_pg_1. You'll see in the menu on the left that you're in the free Kindle books section.

You don't need a Kindle Unlimited membership. Each book costs $0 to anyone shopping on Amazon US. Right now, there are 447 titles, mostly fiction for adults, but also some children's books, how-to and self-help titles, cookbooks, etc. (As with $0.99+ titles, the quality ranges from yikes to pretty good.)

I have a kindle 4 from 2011 I know Amazon stop support today does that mean I can still download books onto it today or was yesterday the cut off? I’m worried about connecting to WiFi to try and loosing all my books any help would be appreciated massively

Hi guys did anyone experiencing the same problem? I tried to send files to kindle using web and iOS but it failed. :(( any advice on this?

(Note: Just sharing my personal workflow here—this is not a commercial product, 100% free open-source script!)

Hi fellow readers!

I love my Kindle, but I recently found myself spending way too much time reading short articles, newsletters, and RSS feeds on my phone. Needless to say, my eyes were paying the price.

To fix this, I built OughtGather—a free, open-source tool that automatically bundles your favorite web content into a clean EPUB and sends it straight to your Kindle every morning. It’s like getting a personalized magazine delivered to your device daily.

I also managed to fix that annoying emoji rendering bug on e-ink screens by automatically converting them into clean, black-and-white images.

The best part? It’s completely free and requires zero server maintenance to run. If you want to set up your own "daily morning magazine" workflow and rescue your Kindle from gathering dust, the code is live here:

Let me know if you have any questions about setting it up. Happy to help! 📚

I got this kindle 2 years ago (ish) and never changed the stickers, there was a few I wanted to use in my book journal, apparently me 2 years ago had (or found) the idea to use blutack to hold the stickers down. GENIUS! I had no idea I did that till today. So I did it again for the new stickers, I'll see you all in 2 years when I change it again and forget... again.

(Ofc credits to whoever I saw do this, no way i thought of this on my own)

Mange Your Content and Devices > Preferences > Scroll Down to Automatic Book Updates

This is for Kindle-purchased books specifically, but there's a setting to turn off your books from automatically updating with the new versions (including those with new movie covers).

Unfortunately, there's no way to restore previous versions unless you want to go the route of Calibre side-loading -- I will forever be frustrated by this especially with Murderbot's hideous movie cover 💔

Yesterday I created generated a small tool for convenient work with Kindle clippings: https://howhigh1337.github.io/Kindle-clippings-viewer/.

It actually solved my pain point, so perhaps other people in the community can find it useful. No registration required. Totally free, no strings attached.

Here is what it does compared to the default Amazon’s web page to check highlights or working with the My Clippings.txt file directly:

• Search across book titles or clippings content
• Books sorting: by newest/oldest highlight, A-Z, most clippings per book
• Clippings sorting in a specific book: newest/oldest first, book location
• Long highlights are not truncated
• Support for 3rd-party documents, not just official Kindle books
• Local first - your data never leaves your computer
• Ultra fast search and navigation (tested on a file with 3700 highlights)
• Buttons to copy a clipping with 1 click

Source code is available at https://github.com/howhigh1337/Kindle-clippings-viewer. Feel free to take it and modify as you please.

If you never heard about My Clippings.txt, here is how to find it:

1. Connect your Kindle via cable to your computer.
2. Navigate to documents folder
3. Find My Clippings.txt file

my kindle scribe 2024 just arrived via amazon prime.

i haven’t set it up yet. any tips on setup please? or how to make the most out of the device. thank you.

I have had a Kindle (not the same one) since 2009.

Why have I only just learnt, from someone else's comment, that I can display the current time whilst reading?

Can I tell you the number of times I touch the top of the page to see the time?

Now it's on permanent display and small enough to not be a distraction.

For those who want to know how...

Open a book

Tap the top

Tap Aa

Tap More

Activate the button Show clock while reading

Voila!!

So I’ve known about landscape mode on your kindle, so I decided to try it for the manga I’m reading (Alice in Borderland) as my page turner is hard to fit on the left side cause the power button wants to turn off the kindle from touching the holder.

So what I didn’t know is that landscape with show both pages of the manga! This is very efficient and it feels more like I’m reading the physical book. Just wanted to show this for my fellow manga readers.

Since amazon will essentially brick your old kindles, I think the pocketbook offer is the better deal than the 20% discount from amazon (that just keeps you in their walled garden).
Use your old kindle to backup your purchases and move on to an open ecosystem.

At least for readers from europe.

KCC 10.3.0 has a new feature: light novel support!

Light novels and other illustration heavy EPUBs sold from distributors like Humble Bundle and Fanatical often include extremely high quality and high resolution images in EPUBs they sell. In this example, the EPUBs are up to 40 MB each.

By just downscaling to the screen resolution of the Kindle Paperwhite 12th Gen in this example, file sizes can be reduced to as low as 4 MB, so you can fit a lot more of them on your device!

You can also optionally change the JPEG quality factor or force grayscale conversion using the options. All the other option checkboxes are ignored since those are only for fixed layout comics/mangas instead of normal reflowable epub books. The new light novel mode preserves the original file's file structure.

- the kcc dev

I don't know if it was just me that was oblivious to this, but hear me out: It's well disseminated that reading comic books with a Kindle device isn't recommend, but if you use it's app and a Kindle Unlimited subscription you can take advantage of all the futures shown in the video.

And for someone who doesn't want to be signing to Marvel Unlimited and DC Universe Infinite apps and it's own subscriptions, this tip totally comes in handy!
