Page Numbers

Add page numbers to every PDF page

Last updated: 2026-10-08

Add Page Numbers is a free online tool that inserts sequential page numbers into a PDF, with four position options — Bottom Center, Bottom Right, Top Center, or Top Right — and a custom starting number, useful when a PDF is part of a larger multi-volume document. Page numbers are placed in the margin area specifically to avoid covering existing page content. Processing happens entirely in the browser via pdf-lib, so the source file is never uploaded to a server. There is no file-size limit and no cap on the number of pages numbered in one operation. The tool requires no account, login, or software installation, and works identically across desktop and mobile browsers, producing a downloadable PDF with numbering applied to every page within seconds of choosing the position and starting number.
