Add Page Numbers to PDF
PDF Tools
Stamp page numbers onto every page of a PDF — position and style handled for you. In-browser, free, private, no signup.
How this page numbering tool works
This tool stamps clean "page / total" numbers (like 3 / 12) at the bottom center of every page and hands back the numbered PDF — processed entirely in your browser, nothing uploaded. It's the finishing step merged documents usually need: combine three reports and the original page numbers stop making sense, so you stamp a fresh sequence over the set. Honest note: numbers are drawn on top of the existing page, so if your document already has page numbers in the bottom center, you'll get both — crop or renumber at the source in that case.
Page numbering tips
- Numbers go bottom-center in a small neutral gray — visible without shouting, and safely inside typical printer margins.
- The format is "3 / 12" so readers always know both position and length — useful for printed handouts that get shuffled.
- Number after merging, not before: merge your files first, then stamp one continuous sequence across the combined document.
- If the PDF already has its own page numbers in the footer, stamping adds a second set — this tool doesn't remove existing ones.
- The stamp is part of the page content afterwards, so it prints and displays everywhere, in every viewer.
Add Page Numbers to PDF — common questions
Latest questions readers ask us about this topic.
Is my PDF uploaded to a server?
No — the numbering is drawn onto the pages by JavaScript in your browser and the finished file is generated on your device. Nothing you open here leaves your machine.
Can I choose the position or start number?
This tool keeps it deliberately simple: bottom-center, starting at 1, in the "page / total" format. That covers the common case — numbering a merged or unnumbered document — without a settings maze.
What if my PDF already has page numbers?
The stamp is drawn on top of the existing page, so you'd end up with two sets of numbers. Remove the original numbers at the source, or accept the doubled footer — the tool can't detect or erase numbers that are part of the page.
Do the numbers survive printing and other viewers?
Yes. The numbers become regular page content — the same as any text in the document — so they show in every PDF viewer and on paper, not just in this tool.
