Add Page Numbers to PDF (Header or Footer)

Upload a PDF, configure your page number style and position, and download the numbered document. Everything runs locally in your browser.

How it works

Number pages in four simple steps—fully private, in your browser.

  1. Upload

    Drag & drop your PDF (local-only).

  2. Choose style

    Header or footer, alignment, start number, “Page X of Y”.

  3. Select pages

    Apply to all or selected thumbnails.

  4. Generate

    Create & download your numbered PDF.

Tip: Need Roman numerals for front matter? Number selected pages first, then run again for the rest.

Flexible numbering

Number all pages or only selected thumbnails—counter respects your selection.

What this tool does

Add professional page numbers to any PDF directly in your browser. You control placement (header/footer), alignment, start number, and formatting. Optionally display “Page X of Y” for formal documents.

Great for

  • Reports, manuals, coursework, proposals, and legal docs.
  • Adding or fixing page numbers before printing/sharing.
  • Selective numbering for appendices or front matter.

Privacy & performance

Everything happens locally on your device—no uploads. Optimized previews make large PDFs responsive, and the counter respects your selected pages.

Tips for perfect results

  • Use a subtle gray (e.g., #4B5563) for a professional look.
  • Keep margins generous for print bleed and bind allowances.
  • Number selected pages first for Roman numerals, then the rest for Arabic.
