Yes of course but i meant if you extract the images from the PDF, the best way to store them is in a .cbz so you get flexibility of having a single file, the aesthetics of a perfect thumbnail without any icon overlay, and you can actually delete individual pages without needing a PDF editor.
Why would i delete pages from a CrazyDad comic? Because if i read 100 pages of a MILF comic like let's say Dr. Brandie, i DON'T want to see the last 2 pages where her husband gets fucked in the ass by another dude.
