What is a PDF Page Number Tool?
A PDF page number tool lets you stamp sequential numbers onto every page of a PDF document. You can choose where the numbers appear — bottom center, bottom left, bottom right, top center, top left, or top right — and customize the font size, starting number, and an optional text prefix like 'Page'. This is useful for preparing documents for printing, adding navigation to reports, or numbering scanned files. All processing runs entirely in your browser using pdf-lib, so your files are never uploaded to any server.

Add Page Numbers FAQ
Is my PDF data secure?
Yes! All processing happens entirely in your browser. Your files are never uploaded to any server, ensuring complete privacy.
Can I start numbering from a number other than 1?
Yes. Use the 'Start Number' field to set any starting value — for example, set it to 5 if the first few pages of your document are a cover or table of contents.
Will existing content be overwritten?
No. The page numbers are added as a new text layer on top of existing content. The original content of your PDF is not modified in any way.
