Stamp sequential page numbers on every page, positioned exactly where you want them.
Add Page Numbers online, free and private
Page numbers turn a loose stack of pages into a navigable document — essential for reports, theses, contracts and anything that will be printed, cited or discussed page by page. This tool stamps a clean sequential number on every page of your PDF, with control over the position, the format (plain number, ‘Page 1’, or ‘1 of 12’) and the number the count starts from.
Everything runs inside your browser. The PDF is opened locally with pdf-lib, the numbers are drawn straight onto each page, and the finished file is handed back to you — nothing is uploaded to a server, so confidential reports and contracts never leave your device.
How to add page numbers in your browser
- 1
Add your PDF
Click ‘Select PDF file’ or drop it onto the page. The document is read locally and its page count appears immediately.
- 2
Pick a number format
Choose a plain number (1, 2, 3), a ‘Page 1’ prefix, or ‘1 of 12’ which includes the total page count — useful when a document might be printed and reassembled.
- 3
Choose position and start number
Place the numbers in any corner or centred at the top or bottom margin. If your document continues from another file, set the starting number to keep the sequence unbroken.
- 4
Stamp and download
Press the button and every page is numbered in one pass in your browser. Download the numbered PDF in seconds.
Why use PDFToolz for this
Six positions, three formats
Numbers can sit in any corner or be centred in the top or bottom margin, and the format can be a bare number, ‘Page N’, or ‘N of Total’. That covers the conventions used by academic style guides, legal documents and business reports alike.
Start from any number
When a document is split across several PDFs — chapters, exhibits, appendices — you can start each file at the right number so the printed set reads as one continuous sequence.
Your document stays private
The numbering is applied with client-side JavaScript, so your PDF is never transmitted. There is no server copy to cache or leak — a real advantage for unpublished manuscripts and confidential agreements.
Free and unlimited
No account, no page cap, no watermark added alongside your numbers. Because the work runs locally, the tool even keeps working offline once the page has loaded.
