About this tool
Add Page Numbers to PDF stamps a clean number on every page so a long document is easy to navigate and reference. It is essential for reports, manuscripts, contracts, and portfolios where readers need to say “see page 12.” The tool prints a number on each page in your browser, so the file never leaves your device. You control the format — use “Page {n}” or a plain number — the starting value, and the position, so the stamp sits where it looks right and avoids covering text. The original is updated into a new file you download. Your page content is untouched — only the properties change. No account, no upload. For anyone assembling a professional-looking PDF from many sources, automatic page numbering is the finishing touch that makes the document feel complete and easy to cite.
Page numbers turn a stack of pages into a citable document. A consultant numbers a proposal so the client can reference “page 7.” An author stamps chapter pages of a manuscript draft. A legal assistant numbers an exhibit bundle for a hearing. A teacher numbers a test so answers map to questions. A homeowner numbers a permit application’s pages before submission. Without numbers, “the third page” is ambiguous; with them, everyone is on the same page. Doing it locally keeps the document on your device, which matters when it holds client or personal detail. You choose the label, the starting number, and where the stamp sits, then get a clean numbered copy. It is a small touch that makes a PDF feel finished and professional. Readers can flip straight to the page they need without guessing where a section begins or ends.
How it works & privacy
Type a label using “{n}” for the number, set a start value and position, then press Run. The tool opens your PDF in the browser with pdf-lib and draws the number on every page, then downloads the result. Nothing is uploaded. Your source stays intact and the numbered version is a new file on your device.
FAQ
Can I choose where the page numbers go?
Yes. You set the label, starting number, and position so the stamp sits where it looks right and does not cover your text.
Is my PDF uploaded when numbering?
No. Numbering happens locally in your browser; the document never leaves your device.
What does {n} mean?
It is replaced by the page number. Use “Page {n}” for “Page 1”, or just “{n}” for a bare number.
