Add Page Numbers to PDF is a free online tool that inserts page numbers at any position on your document. WayPDF adds page numbers entirely in your browser using pdf-lib — your document never leaves your device, ensuring complete privacy.

Common use cases include numbering legal documents for court filing, adding page numbers to academic papers and theses, organizing multi-page business proposals, paginating eBooks and manuals, and preparing documents for professional printing. Choose from six positions and set a custom starting number.

Browser-based processing means your document is modified on your own device. There's no upload, no server processing, and no risk of data exposure. The actual document content remains unchanged — only page numbers are added.
