+Supported input formats include JPG/PNG image files in folders, archives like CBZ, or PDFs.
 Supported output formats include MOBI/AZW3, EPUB, KEPUB, CBZ, and PDF.
-
-The absolute highest quality source files are DRM-free PDFs from [Humble Bundle](https://humblebundleinc.sjv.io/xL6Zv1)/Fanatical.
-The PDFs are often x12000 resolution or better, basically print quality.
-
-KCC's main goal is maximum image quality at significantly smaller file size. For example, KCC
-
-1) can compress a 600 MB manga volume from Humble Bundle to 100 MB.
-   This is mostly accomplished by downscaling to the native resolution of your specific device.
-   This can also improve battery life, page turn speed, and general performance
-   on underpowered ereaders with small memory and storage capacities.

-2) fixes black levels to avoid gray/faded blacks found in many Kindle Store manga

 Just drop your input files into the KCC window, hit convert, and USB drop the output files onto your device's `documents` folder!

-Then all your usb loaded comic files will show up next to all your normal books in your ereader library!
+**WARNING**: Kindle Scribe 2025 support may not be possible. Does not work well currently.

-The final result looks incredible on my 10" Kindle Scribe: https://www.youtube.com/watch?v=2CIHW2N9Enc
+**NEW**: PDF output is now supported for direct conversion to reMarkable devices! 
+When using a reMarkable profile (Rmk1, Rmk2, RmkPP), the format automatically defaults to PDF 
+for optimal compatibility with your device's native PDF reader.

-**WARNING**: Kindle Scribe 2025 MOBI support may have blank pages. Use PDF instead.
+The absolute highest quality source files are print quality DRM-free PDFs from Kodansha/[Humble Bundle](https://humblebundleinc.sjv.io/xL6Zv1)/Fanatical,
+which can be directly converted by KCC.

-The GUI looks like this, built in Qt6. There are a lot of options, but most people only care about the ones checked below:
+Its main feature is various optional image processing steps to look good on eink screens, 
+which have different requirements than normal LCD screens.
+Combining that with downscaling to your specific device's screen resolution
+can result in filesize reductions of hundreds of MB per volume with no visible quality loss on eink.
+This can also improve battery life, page turn speed, and general performance 
+on underpowered ereaders with small memory and storage capacities.

+KCC avoids many common formatting issues (some of which occur [even on the Kindle Store](https://github.com/ciromattia/kcc/wiki/Kindle-Store-bad-formatting)), such as:
+1) faded black levels causing unneccessarily low contrast, which is hard to see and can cause eyestrain.
+2) unneccessary margins at the bottom of the screen
+3) Not utilizing the full 1860x2480 resolution of the 10" Kindle Scribe
+4) incorrect page turn direction for manga that's read right to left
+5) unaligned two page spreads in landscape, where pages are shifted over by 1
+6) Removing without blur the rainbow effect on color eink Kaleido 3 due to manga screentones
+7) Fixing page order problems due to Windows sort being different than Kindle/Kobo sort

 Simply drag and drop your files/folders into the KCC window, 
 adjust your settings (hover over each option to see details in a tooltip), 
 and hit convert to create ereader optimized files.
+You can change the default output directory by holding `Shift` while clicking the convert button.
 Then just drag and drop the generated output files onto your device's documents folder via USB.

-## Kindle Jailbreak for KOreader
-
-Jailbreaking to use KOreader is optional. KCC works just fine with the native mobi manga viewer.
-
-But if you jailbreak your Kindle, you'll unlock additional features like:
-
-1) compatibility with image formats better suited for manga like 4-bit PNG and WEBP. This enables better quality at **half the file size** compared to JPG which must be 8-bit.
-   This is visually lossless since eink screens are 4-bit.
-3) no dependency on kindlegen, which can mean **twice as fast conversions** since you can convert to CBZ directly.

 ### A word of warning
 **KCC** _is not_ [Amazon's Kindle Comic Creator](http://www.amazon.com/gp/feature.html?ie=UTF8&docId=1001103761) nor is in any way endorsed by Amazon.
 Amazon's tool is for comic publishers and involves a lot of manual effort, while **KCC** is for comic/manga readers.
