Free Online PDF Page Number Tool
Add Page Numbers is a fully web-based tool that numbers every page of your PDF right in the browser. It draws text directly onto the original pages using PDF-lib, supports multiple formats, and embeds font subsets automatically so the output stays clean and compact.
A report that runs to dozens of pages, a manual over a hundred pages, a contract that's about to be bound — without page numbers, flipping through and citing pages is a hassle. Our tool numbers the entire document in seconds: you can leave the cover unnumbered and set any starting number.
Common use cases
- Long document formatting — number reports, theses and manuals consistently for easier reading and reference.
- Contract binding — add page numbers to multi-page contracts so a single page can't be swapped out.
- Post-processing PDFs — pair with our merge and split tools to number a whole batch of documents after joining them.
Why it beats desktop software
- Works anywhere — no installation needed. Runs on Windows, macOS, Linux, iOS and Android.
- Zero privacy risk — files are processed locally and never travel over the network.
- Crisp original pages — text is drawn directly on the original PDF without recompressing the page content.
