Add Page Numbers to PDF

Stamp page numbers onto a PDF — choose the format, position, starting number, size, and color. Live preview, 100% in your browser.

Add Page Numbers to PDF stamps clean, consistent page numbers onto every page of a PDF, entirely in your browser. Choose a format — a plain number, a number with the total, or ‘Page X of Y’ — then set the position (any of six corners and centers), the starting number, font size, margin, and color, while a live preview of the first page updates as you go. The numbers are drawn as real text on top of your content, so the original stays intact and selectable. Everything runs client-side with pdf-lib, so your document never leaves your device.

Frequently Asked Questions

What number formats are available?

You can use a plain number (1), a number with total (1 / 10), ‘Page 1’, or ‘Page 1 of 10’. The live preview shows exactly how each will look.

Can I start numbering at a specific number?

Yes. Set the starting number to anything you like — useful when a document is a continuation, or when the first pages are a cover you want to skip counting.

Where can the numbers go?

Any of six positions: the top or bottom, aligned left, center, or right. Adjust the margin to move them closer to or further from the edge.

Does it change the existing content?

No. The numbers are drawn on top as real text; your original page content, including selectable text, is preserved underneath.

Are my files uploaded?

No. Numbering happens in your browser with pdf-lib, so your document never leaves your device.
