Accepts a single PDF. Numbers are printed in the Helvetica font in dark grey and become a permanent part of each page.

How to add page numbers to a PDF

  1. Add your PDF.
  2. Pick a position (e.g. bottom center) and a format: “1”, “Page 1” or “1 of N”.
  3. Set the starting number and font size if needed.
  4. Click Add page numbers and download the result.

Supported files and limitations

  • Numbers are stamped on top of existing content. On pages with edge-to-edge content they may overlap it — reduce the font size or pick a different corner.
  • The numbering counts every page; there is no way to skip a cover page yet, but you can start counting at 0.
  • Password-protected PDFs must be decrypted first.

Common problems

  • Numbers overlap footers — switch between top and bottom positions, or lower the font size.
  • Rotated pages show numbers on the “wrong” edge — positions follow the original page orientation stored in the file.

What happens to your files?

This tool runs entirely in your browser. Your file is opened in your device's memory, processed there, and the result is saved back to your device. The document is never uploaded to a server. You can confirm this yourself: open your browser's developer tools, switch to the Network tab, and process a file — no request contains your document. Closing the tab discards everything.
