Am I understanding this that you have some number of .pdf files that are 40-60 pages each and within them, there exist documents varying from 2 to 10 pages, and your task is to parse them?

If so, how many .PDFs are we talking here? You said on paper it’s like 8cm high? So like 1000 pages ish?

So like 20 .PDFs?

Just… Do it, dawg. The amount of time you spent on this post you coulda finished 1 of those PDFs. That’s 5% of the task. Do that 19 more times.

If you’re asking “can Adobe Acrobat break a 60 page .pdf into some number of .PDFs based on page numbers I tell it to,” the answer is yes.
