Private and secureWhat Is the Add Page Numbers to PDF Tool?
The Add Page Numbers to PDF tool lets you insert page numbers into a PDF directly from your browser. You can use simple numbers, Page 1, Page 1 of 10, or a custom prefix. You can also control page selection, position, font size, color, margin, font weight, and the starting number.
It is useful for reports, contracts, manuals, ebooks, research documents, invoices, training materials, and other multi page PDFs that need clear page references.
Why Use This Tool?
Page numbers make documents easier to navigate and easier to reference during meetings, printing, reviews, classroom work, and record keeping. Instead of editing every page manually, you can apply consistent numbering across an entire PDF or only selected pages.

- Select the numbering format.
- Choose the position and visual settings.
