Add Page Numbers to PDF

Stamp page numbers onto every page of a PDF, right in your browser.

About this tool

Stamps a page number onto every page of a PDF, in the position and format you choose. Everything runs locally in your browser using the open-source pdf-lib library; your file is never uploaded anywhere.

Frequently asked questions

Can I skip numbering the first page (like a cover page)?
Not in this version — every page gets numbered. Set "Start number" to 0 if you want the first page to read "0" instead of "1".
What does "N" mean in the format options?
N is the total page count — so "1 / N" on page 3 of a 10-page document reads "3 / 10".
Are my files uploaded anywhere?
No — everything happens entirely on your device. Nothing is sent to any server.
