KCC - Maximize eInk manga quality with 2D DFT and dithering
Show HN: Using 2D DFT, dithering, etc. to maximize eInk manga image quality
KCC (Kindle Comic Converter) optimizes comics and manga for E-ink ereaders like Kindle, Kobo, and ReMarkable. It delivers true fullscreen, margin-free pages and uses advanced techniques like 2D DFT to eliminate the rainbow effect on Kaleido 3 color eink, plus dithering for smaller files. It compresses a 600 MB volume to 100 MB, fixes black levels, and auto-detects 2-page spreads. Runs on Windows, macOS, and Linux, supporting CBZ, EPUB, PDF, and more. Just drop files, convert, and USB transfer to your device.
KCC's main goal is maximum image quality at significantly smaller file size.

Comic books and manga are amusingly amount the least digitizable mediums as you have the choice of good resolution but an unpleasant reading experience with lit screens on a desktop, laptop, tablet or phone and low res or lack of spreads on an e reader. Even more so when you're missing out on colour.

I read a lot of manga and comic since my childhood but never even once in my life I have able to enjoy manga on tablet/mobile as much as I enjoy them as physical volume. But looking forward to use Kindle Comic Converter
