About adding page numbers to a PDF
This tool adds page numbers to a PDF. Choose the position, the number format (1, Page 1, 1 of N, or Page 1 of N), the starting number and the font size, and it stamps the numbers onto every page, ready to download. It runs entirely in your browser, so your file is never uploaded.
How PDF Page Numbers works
How to number a PDF
- Drop your PDF onto the box.
- Pick the position, format, starting number and size.
- Click to add the numbers and download the new PDF.
Flexible formatting
Place numbers in any corner or centred, top or bottom, and choose a plain number or a "Page X of N" style. The starting number lets you skip a cover page or continue from another document.
Private and free
The numbering is done locally with the PDF-lib engine — your document stays on your device, with no sign-up and no limits.
