  1. Upload a PDF

    Drag and drop a PDF onto the tool, or click to browse and select the file from your device.

    Pick one of six positions (top or bottom, left/center/right), a format (1, Page 1, 1 of N or - 1 -), a starting number, and whether to skip the first page. Adjust the font size in the live preview.

    Click the button to build the numbered PDF in your browser and save it to your device.

Key features

Supported formats

  • Input: PDF (.pdf), one file
  • Output: PDF (.pdf) with numbers drawn onto the pages

Privacy and security

Numbering runs locally in your browser with pdf-lib. The PDF is processed on your device and the numbered copy is downloaded from your browser — no upload, no storage.

Limitations

  • One file at a time.
  • Numbers are drawn onto the page as text — pages that already have printed numbers will show both.

Frequently Asked Questions

Can I add page numbers to all pages at once?

Yes. Choose your position, format and starting number, then click Apply — every page is numbered consistently before you download.

Can I skip the first page?

Yes. Enable "Skip numbering on the first page" to leave a cover page unnumbered while numbering the rest of the document.

Can I start numbering from a number other than 1?

Yes. Set a starting number, e.g. 5, so page 1 shows 5, page 2 shows 6, and so on — useful when the PDF continues from another document.

Is my PDF uploaded to a server?

No. Everything runs in your browser with pdf.js and pdf-lib, so your file never leaves your device.
