Show HN: eInk Optimized Manga with Kindle Comic Converter (+Kobo/KOreader)

Kindle Comic Converter optimizes black & white (or color) comics and manga for E-ink ereaders like Kindle, Kobo, ReMarkable, and more. Pages display in fullscreen without margins, with proper fixed layout support. KCC runs on Windows, macOS, and Linux. 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 3) fixes the rainbow effect on Kaleido 3 color eink without blur using the Discrete Fourier Transform (community PR)

It can also semi-automatically join pre-split 2 page spreads and has several KOreader optimizations as well.
