How to Add Page Numbers to PDF Online for Free in 2026
Page numbers make documents look professional, easier to reference, and more organized — especially for reports, theses, contracts, books, or presentations. Our free tool adds them directly in your browser without installing software or uploading files.
Using PDF-Lib, we overlay text layers with your chosen page number format on every page — keeping original content untouched.
Key Features
- Custom Position & Alignment: Top/bottom, left/center/right.
- Flexible Format: Use {n} for current page, {total} for total pages (e.g., "Page 3 of 15").
- Starting Number: Begin from any number (useful for merged documents).
- 100% Private: No server upload — everything stays on your device.
- Real-time Preview: See your PDF before processing.
Common Use Cases
Students numbering thesis chapters, professionals paginating reports, lawyers adding numbers to legal briefs, authors preparing manuscripts, accountants organizing financial statements — anywhere clear pagination is needed.
