Why Add Page Numbers to PDFs?

• Professional Documents: Page numbers are expected in reports, proposals, and formal documents
• Easy Navigation: Readers can reference specific pages in discussions and reviews
• Print Organization: Keeps printed pages in order if they get mixed up
• Table of Contents: Page numbers make tables of contents functional
• Legal Requirements: Many legal documents require numbered pages for reference
• After Merging: Merged PDFs often have inconsistent or missing page numbers

How to Add Page Numbers

1. Open the Add Page Numbers tool
2. Upload your PDF
3. Choose the position: top or bottom, left, center, or right
4. Select the number format: 1, 2, 3 or i, ii, iii or Page 1 of N
5. Set the starting number (useful when numbering continues from a previous document)
6. Customize font size and margins
7. Click Apply and download your numbered PDF

Position Options

The most common page number positions follow standard document formatting conventions:

• Bottom Center: The most common position — professional and balanced. Standard for academic papers and reports.
• Bottom Right: Common in business documents and books. Easy to see when flipping through pages.
• Top Right: Used in legal documents and technical manuals. Visible without scrolling to the bottom.
• Alternating (Inside/Outside): Professional book-style numbering where left pages show numbers on the left and right pages on the right.

Number Format Options

• Arabic (1, 2, 3...): Standard numbering for most documents
• Roman (i, ii, iii...): Traditional for prefaces, introductions, and front matter
• "Page X of Y" format: Shows total page count — helpful for long documents where readers need context
• Custom prefix/suffix: Add text before or after the number (e.g., "Appendix A - Page 1")

Pro Tip

If your document has a cover page, start numbering from page 2 and set the starting number to 1. This gives you a clean cover page without a number while the rest of the document is properly numbered starting from 1.

Common Scenarios

After Merging PDFs

When you merge multiple PDFs, the resulting document often has conflicting or duplicate page numbers. Adding fresh page numbers after merging creates a consistent, professional document.

Scanned Documents

Scanned documents typically don't have digital page numbers. Adding numbers makes them easier to reference and navigate, especially for multi-page scans of books, manuals, or records.

Academic Papers

Most academic formatting styles (APA, MLA, Chicago) require specific page number placement. Our tool lets you match your required style exactly.

Privacy & Security

Page numbering is performed entirely in your browser using client-side JavaScript. Your PDF is never uploaded to any server. Process confidential reports, legal documents, and personal files with complete privacy.
