I have a 34 page .docx document with a table of contents and many section breaks. When I go to save it as a PDF, Word chops up the content into 311 pages, putting a little bit from each normal page into the header section of the 311 pages. It does this both on my Word copy of the doucment and on my newly created PDF.
I've tried several converters and they all make 300 page pdfs. I know that there must be some marker in my word doc that tells the PDF makers to interpret it this way, but I can't find it.
