Bicubic downsampling help?! via /r/pdf


Bicubic downsampling help?!

This might be long apologies in advance. I have a bunch of pdfs which I have been using bicubic downsampling to reduce their size as they are too big for what I need (125mb tops) I’ve been downsampling to 190ppi for images over 200ppi. I did this to one pdf (let’s call it book A) but it was still too big (it went from around 230 mb to 188 mb) so I then split book A into two parts and downsampled part 1 (it was still too big once split) however the quality of part 1 after downsampling was much less and to the point of unreadable (it then became 20mb). Any ideas why the quality changed so much, I didn’t change any settings, would the number of pages in the pdf affect the downsampling? Really sorry if this makes no sense but I’m just so confused, thanks!
