I have a couple textbooks in PDF form (not sloppy scans but high-quality, searchable, linked textbooks). I wanted to move them to Microsoft OneNote as this is where I do all my school work so it would be nice to have it all in one place. OneNote only allows me to insert PDF printouts up to 50kb however and these are much larger. So then I decided I could cut the PDF down and save it into separate PDF's that are a chapter in length and would be small enough to fit into my OneNote. But I don't know how to break down a 700 page PDF into smaller pieces. Any advice? I have it open in Adobe Acrobat Reader DC and am on a Mac if that matters.
