## What it is
KCC (Kindle Comic Converter) is a Python application with a Qt6 GUI and CLI that converts comics and manga from image folders, CBZ/EPUB archives, or PDFs into formats optimized for e-ink ereaders like Kindle, Kobo, and ReMarkable. It downscales images to device-native resolution, fixes black levels and color e-ink artifacts, and handles two-page spreads for fullscreen margin-free reading.

## Use cases
- convert manga PDFs to Kindle-optimized files
- compress large comic archives for e-readers
- prepare webtoons for Kobo e-ink display
- fix gray blacks on Kindle manga
- split two-page spreads for fullscreen reading
- convert CBZ comics to EPUB for ereaders

## When to choose
- you read comics or manga on an e-ink device like Kindle, Kobo, or ReMarkable
- you need smaller file sizes and better image quality than generic converters
- you want fullscreen margin-free pages and spread handling

## When to avoid
- you need DRM-protected source files converted
- you target non-e-ink devices or general-purpose ebook conversion
- you need text-based book conversion rather than image-based comics
