Add Page Numbers

Stamp 1-based page numbers onto the document in the position you choose. The existing content is untouched.

About this tool

Number every page of a PDF without a full editor. Choose the corner or centre, set the font size, and skip the first page when the document starts with a cover sheet.

How to use the Add Page Numbers tool

  1. Choose a PDF. Select the document to number.
  2. Pick a position and size. Choose bottom centre, bottom right or top right, and the font size in points.
  3. Number and download. Click Add page numbers. The numbers are stamped from 1 in document order.

Supported formats

Frequently asked questions

Does it start from 1?

Yes. The first numbered page is labelled 1. The skip-first option keeps the cover unnumbered but does not shift later numbers.

Are existing numbers overwritten?

No. The tool draws on top; it cannot detect or erase numbers already in the content.

Can I use formats like 'Page 1 of 12'?

This tool stamps plain numbers. Custom prefixes are not supported.

Which font is used?

Helvetica, which keeps the output compact and renders reliably everywhere.

Privacy

Everything you enter stays in this browser tab. There is no upload endpoint for tool inputs, no account, and no server-side copy of your text or files. Results are produced locally and disappear when you close the page.

No account is required and no file is ever uploaded. See the privacy policy for details about analytics and the limited data this site stores.

Known limitations

  • Plain numbers only — no 'Page X of Y' prefix or suffix.
  • Text is drawn in Helvetica, so some non-Latin scripts will not render.
  • Numbers already present in the content are not detected or removed.
