Number your pages for clarity and reference
Page numbers make documents easier to navigate, cite, and print. Whether you are preparing a contract for signing, a report for review, or a manuscript for submission, the Add Page Numbers tool stamps clean, consistent numbers onto every page of your PDF in seconds.
The stamping is done in your browser with pdf-lib, which draws the numbers directly onto each page. Because the work is local, no upload takes place and your document stays private — important when you are numbering sensitive legal or financial paperwork.
Control position and format
You decide where the numbers sit — a corner or the center of the header or footer — and how they read. Choose a simple sequence like 1, 2, 3, or a formatted style such as Page 1 of 20 for longer documents. The numbers are drawn as real text on the page, so they stay sharp at any zoom level and survive printing.
The tool is free, adds no promotional watermark of its own, and requires no account. There are no page limits beyond your device's memory, and it works on both desktop and mobile browsers.
