[APP] KinBo - Alternative to Kindle Comic Converter (KCC)

[GigaCat]

Hey everyone,

If you’re looking for a way to optimize and package manga, comics, or webtoons directly on your Android phone/tablet without needing a desktop PC, check out KinBo: an on-the-go Android alternative to Kindle Comic Converter (KCC).

It handles the entire optimization pipeline right after a download:

• Exact E-Reader Profiles: Pixel-perfect resolutions for Kobo (Clara, Libra, Sage, etc.), Kindle (Paperwhite, Oasis, Scribe, Colorsoft), Onyx BOOX, reMarkable, and more—with tailored support for both monochrome and color e-ink screens.
• Smart E-Ink Tuning: Automatic margin border cropping, double-page spread splitting (with Manga right-to-left order), gamma contrast tuning for washed-out scans, and 2D FFT rainbow moiré removal.
• Webtoon & Mihon Integration: Slices continuous vertical webtoons into natural reading pages and directly packages Mihon / Tachiyomi chapter folders into complete volumes in seconds.
• Modern Format Engine: Handles CBZ, CBR, raw folders, EPUB, and PDF with native decoding for JPEG XL (.jxl), AVIF, HEIC/HEIF and others.
• Ready-to-Read Outputs: Exports to native KEPUB (Kobo), EPUB 3 (Send-to-Kindle ready), PDF, and CBZ in a background queue.
