Add Page Numbers to PDF Online Free

Add Page Numbers is a free online tool that automatically inserts page numbers onto every page of your PDF document. Customize the position (top or bottom, left, center, or right) and set a custom starting number. All processing runs in your browser — no file upload, no signup, no software needed.

Why Add Page Numbers to PDFs?

Page numbers are a fundamental requirement for professional documents. They make navigation easier, allow readers to reference specific sections in meetings or reviews, are required by many academic and legal submission guidelines, ensure printed copies can be reassembled if pages get shuffled, and make your document look polished and complete.

Reports, theses, legal briefs, manuals, proposals, and any multi-page document destined for printing or professional submission should have page numbers. This tool adds them in seconds, directly to the PDF, without disturbing any existing content.

How It Works

Using PDF-lib, the tool overlays a page number label on each page of your PDF. You control the horizontal and vertical position, and the starting number. The numbers are added as a text overlay that does not affect the existing content — they simply appear at the specified position on each page.

Frequently Asked Questions

Can I skip numbering the first page (cover page)?
Currently all pages are numbered. For advanced control, consider using our Edit PDF tool to manually add a number to specific pages.

Can I choose the font style?
The tool uses a clean standard font. Advanced font customization may be added in a future update.
