Add Page Numbers to PDF
Stamp page numbers onto every page in the position, format, and size you choose, entirely inside your browser.
How does this tool work?
Your PDF is parsed directly in the browser, and a page number is drawn onto every page at the position and in the format you choose. The original page content is left untouched — the number is added on top, not replacing anything. Nothing is uploaded to a server at any point.

Features & benefits
Why this runs entirely in your browser
PDF files often contain sensitive or confidential documents, so nothing is uploaded to a server. Parsing and stamping the page numbers all happens locally using your browser's own processing power, directly in the tab.
Common uses
Numbering a report or contract before printing, adding "Page X of N" to a long document for reference, or numbering a scanned bundle of pages for easier citation.
Frequently asked questions
A few things people usually want to know before trusting the numbers.
Yes. Use the "Start at" control to set the first page's number to anything you like — useful when this document continues numbering from another file, like an appendix.
N stands for the total number of pages in the document, so "Page 1 of N" becomes something like "Page 1 of 12" once applied — it updates automatically to match your file's actual page count.
It's placed with a margin from the edge of the page, so it normally lands in blank space. If a page's content already extends very close to that corner, the number may overlap it — try a different position if that happens.
PDFs that require a password just to open can't be processed, since the tool can't read their contents without that password. PDFs that only have owner or permission restrictions but no open password can usually still be numbered without issue.
No. All processing happens locally in your browser using JavaScript running on your own device. Nothing you upload here is ever sent to a server, stored remotely, or shared with anyone — closing the tab clears everything.
