Add Page Numbers to PDF
Stamp a page number at the bottom of every page — pick the format and position.
This tool stays free by showing a short ad for larger files: 20 pages or fewer is free, 21-50 pages = 1 ad, 51-100 pages = 2 ads, 100+ pages = 3 ads.
How it works
A number is drawn at the bottom of each page without re-rendering the page content, so quality stays exactly as-is.
Is my file uploaded anywhere?
No — everything happens locally in your browser. Your PDF never leaves your device.
