27-43MB for each of the color pages is bloated as fuck. Should of used lossy jpg. Greyscale PNG's could of made the black & white pages smaller too. I got the Black & White pages from 185MB down to 99.6MB with lossless PNG, 17 colors. https://www.insidescanlation.com/etc/how-to-edit-manga-with-photoshop/rawr/editguide/3 Just be careful with limiting colors, as if you haven't leveled out much, some pages will need more colors. For this gallery, colors set to 17 with Adaptive & Selective types was fine.
