    From the README

    Kindle Comic Converter optimizes black & white comics and manga for E-ink ereaders like Kindle, Kobo, ReMarkable, and more. Pages display in fullscreen without margins, with proper fixed layout support. Supported input formats include JPG/PNG/GIF image files in folders, archives, or PDFs. Supported output formats include MOBI/AZW3, EPUB, KEPUB, CBZ, and PDF.

    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.

    The absolute highest quality source files are print quality DRM-free PDFs from Kodansha/Humble Bundle/Fanatical, which can be directly converted by KCC.

    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 storage capacities.
