Add Page Numbers to PDF
Stamp page numbers on every page of a PDF — position, format and start number are yours to choose. Free, instant, private.
Private by design: this tool runs entirely in your browser. Your files are never uploaded to a server, and nothing is stored.

Why number your PDF pages?
Page numbers turn a stack of pages into a document you can actually navigate: readers can find their place after printing, you can point someone to “page 14” in an email, and numbered pages are expected in reports, theses, contracts and legal filings.
This tool stamps the numbers directly into the PDF in your browser — the file never leaves your device, so private contracts and unpublished manuscripts stay private. Every page is copied exactly as it was; only the numbers are added.
