When you've merged several documents into one, or you're preparing a report to print or submit, missing page numbers make the order easy to lose. And if you only have the PDF and not the original Word file, adding numbers is surprisingly fiddly. Do it in the browser: stamp a number on each page, and the file never leaves your device.
Adding page numbers
- 1Open Add page numbers.
- 2Upload the PDF you want to number.
- 3Check the options and run it — a new PDF with a number on each page is saved.
TipIf you first merge several PDFs and then add numbers, you get a single continuous numbering across the whole document. Remember the order: merge, then number.
When you'd use this
- •Number the pages of a report or assignment for submission
- •Lock the order of a multi-page contract or quote
- •Keep printed pages easy to reorder if they get shuffled
Why in-browser processing helps
- •The document is never sent to a server, so there is nothing to leak.
- •No sign-up, no software to install.
- •Once loaded, it works offline too.
