Add Page Numbers to PDF
Number all or selected PDF pages with a chosen starting number, position and text size.
Choose a PDF, select the page range, starting number, position and text size, then download a numbered copy. Processing happens locally. Adding page numbers changes the PDF and can invalidate an existing digital signature, so keep the signed original when verification matters.
Your PDF and any signature or watermark stay in this browser.
Number the selected page range without uploading the document.
Page numbers are drawn as new visible text on the selected pages.
How to use this tool
- Choose a PDF and page range.
- Set the starting number, optional prefix or suffix, size and position.
- Create and download the numbered PDF.
Ways to use it

Supported files and limits

Common questions
Can numbering start after the first page?
Yes. Choose a starting page and starting number; pages before that range remain unchanged.
