# Add page numbers to a PDF

Stamp page numbers onto an existing PDF, with position and start value.

## How it works

Adds page numbers to an existing PDF at a chosen position, with a configurable starting number and optional "page X of Y" format.

Numbers are drawn onto the page content rather than added as an annotation, so they print and survive flattening. That also means they cannot be removed afterwards without editing the content stream — this is a one-way operation, so keep the original.

The starting number is separate from the page index, which matters for documents with front matter. Setting the start to −2 means the first three pages are unnumbered and page four becomes page 1.

> This tool runs entirely in your browser. Nothing you enter is sent to a server, logged or stored, and the page keeps working with the network disconnected.

## Common questions

### Can page numbers be removed later?

Not easily. They are drawn into the page content rather than added as an annotation, so removal means editing the content stream. Keep the original.

### How do I skip numbering the cover pages?

Set a negative or offset start value, so numbering begins on the page you want to be page 1.
