About this tool
Stamping page numbers onto a PDF
The tool writes page numbers onto every page of your PDF — position, starting number, and format are yours to choose. The numbers become part of the page content, so they print, copy, and display exactly like the rest of the document.
The positions that make sense
Bottom-center suits reports and manuscripts; bottom-right suits documents that get bound or filed; bottom-left for right-to-left reading traditions. Choose the starting number when the PDF continues an existing document — page 15 of a longer work starts at 15.
The whole job runs in your browser
The PDF is read, numbered, and written entirely on your device — nothing is uploaded. Sensitive documents get their numbers without ever leaving your hands.
Frequently asked questions
Can I choose where the numbers appear?
Yes — six positions across the bottom and edges of the page, plus the starting number and format.
Will the numbers overwrite my content?
The numbers are placed at the page margins you choose — content in that region will sit under the number, so pick a position with clear space.
Does the tool modify my original file?
No — the numbered version is a new document; the original on your device stays untouched.
