How to add page numbers to a PDF
Adding page numbers helps readers navigate and cite long documents. This tool draws numbers directly onto each page with pdf-lib, letting you choose where they sit, what number to start from, and whether to show plain numbers or formats like "Page 1 of 20". It all runs in your browser.
Key features
- Choose corner or centered position
- Set the starting number
- Formats like 1, Page 1, or 1 / N
- 100% client-side — no upload
Frequently asked questions
Can I start numbering from a page other than 1?
Yes — set any starting number, useful when a cover page shouldn't be counted.
Where are the numbers placed?
You choose a corner or the center of the footer; the number is drawn onto each page.
Is my PDF uploaded?
No. Numbers are added in your browser and the file never leaves your device.
