Nickel itself will grayscale and dither those.
@NiLuJe, Sorry, I'm not sure i understand. On my laptop (i.e. the "library"), I'd like to keep the original epub/cbr/mobi files, with all the color and everything else untouched. But on my Kobo, I want all images, whether the book's cover or the book's contents, be all grayscale. What must I do to make that happen? The purpose is to save space on my Kobo Forma. (A secondary benefit is probably faster page turns and book loading times.)
