About the PDF format
Page numbers exist for the reader: they let people cite 'page 7', check that nothing is missing, and put printed pages back in order after a fall off the desk. Documents assembled from scans and merges often lack them because each source carried its own — or none. Adding them afterwards is a two-minute finishing step that makes a document feel deliberate.
About the PDF format
The result is your PDF with a small page number in 'n / total' format stamped at the bottom centre of every page, in a neutral grey that works on light and printed pages. The rest of each page is untouched — content is never recompressed or redrawn, only the number is added.
Frequently asked questions
Where do the numbers appear?
At the bottom centre of every page, in the format '3 / 12' — current page over total pages — in a small, discreet grey type that reads well in print.
Can I number only some pages, or start from a different number?
This tool numbers every page starting at 1, which covers most reports and submissions. For excerpts, split the pages you need first with Split PDF, then number the result.
Are my documents uploaded to a server?
Never. The numbering happens in your browser with pdf-lib. Your PDF is read and rewritten on your own device; we cannot see, store, or share it.
Does adding numbers change my pages?
Only by adding the number itself. Text, images, and layout are untouched, and nothing is recompressed — and your original file stays exactly as it was.
