Could not extract PDF because of page limit
Why is there a 500 page limit for processing?
I went to www.ilovepdf.com and was able to extract pages from a 570 page PDF. And everything else about the experience was better as well: no login required, faster upload, more intuitive UI, and no annoying page limit.
