Kindle Comic Converter

Kindle Comic Converter is a Python app to convert comic files or folders to ePub or Panel View MOBI.
It was initally developed for Kindle but since v2.2 it outputs valid ePub 2.0 so despite its name, KCC is actually a comic to EPUB converter that every e-reader owner can happily use.
It can also optionally optimize images by applying a number of transformations.

And it’s on GitHub!
