How do I add page numbers to a PDF?

Drop your PDF into the tool, choose a position (bottom centre is the default), set the starting number, then click 'Add page numbers' and download the result.

Can I start numbering from a number other than 1?

Yes. Use the 'Start at' field to set any starting number. For example, enter 5 to begin numbering at page 5.

Will page numbers be added to every page?

Yes. The tool stamps a number on every page of the PDF using the position, size, and colour you choose.

Does adding page numbers affect the rest of the PDF content?

The numbers are drawn on top of the existing page content. Text, images, and all other content remain unchanged.

Yes. Your PDF is processed entirely in your browser using pdf-lib. Our servers are not involved at any point.

How it works

This tool uses pdf-lib, a pure JavaScript PDF library. It loads your PDF in memory, uses the built-in Helvetica font to draw a page number on each page at the position you choose, and downloads the result. All without leaving your browser tab.

Processing runs in your browser

All processing happens inside your browser. pdf-lib modifies the document structure entirely in memory. Our servers are not involved at any point.
