Simply put, the amount of pixels in most comics, and the compression used to store those pixels (or lack thereof), is usually overkill for the type of screens I read from, and this program attempts to rectify that by doing hundreds of simple but tedious image operations in just a few seconds. Over the 11 published volumes, that amounts to over 1GB saved (which is a lot when you consider many e-Readers still have only 4GB)! And that's without touching the resolution, the size can be further reduced by another 50MB by downscaling to the actual display resolution - easily tripling the amount of manga that can be stored on your device, while maintaining the same perceived quality. cbz files in bulk so they use less space on my Kobo.įor example, by repacking with WebP with the default settings, this can cut the size of the first volume of Chainsaw Man from 180MB to just under 96MB, without affecting image quality. I prefer to keep the original files intact on Calibre on my computer, but use this tool to optimize the.
This isn't really a problem most of the time, but it limits what I can put on my Kobo e-Reader (which has 'only' 32GB of storage). I own a large digital manga library, which unsurprisingly uses a lot of space. Originally, I created this to save disk space.
