Numbering a document made of several PDFs
Combine the files first with Merge PDF, then add page numbers, so the numbering runs straight through.
If you still have the Word file
In Microsoft Word, use Insert → Page Number before saving as PDF. Numbers added in Word follow sections and headers, which is useful for long reports.
