Ok, thats's your opinion but i think that pdf doesn't add any value whatsoever to a bunch of simple images. Also i can simple delete the not needed ones. How do you do that quickly with pressing one single key?there is nothing wrong with pdf
if u know how to use it
all the different comix i download there are in jpg or webp
i convert to pdf
Seems you have to much time on your hands if you really convert everything to pdf.
Btw. have you ever tried something like irfanview?
