How to Add Page Numbers to a PDF

Quick answer: Stamp page numbers onto an existing PDF with control over position, format, and starting number. Open PDF 页码 — everything runs locally in your browser, and files never leave your device.

Steps

1. Upload the PDF to the Page Numbers tool.
2. Pick a position (bottom-center is the most common), format, and starting number.
3. Exclude the cover page if you want numbering to start on page 2.
4. Download the numbered PDF.

Important notes

• If the document already has printed numbers baked into the text, adding a second set looks messy — use the header/footer tool to replace or mask the old ones first.
• Numbers are rendered as real text on top of the page, so they stay sharp at any zoom level.

Common questions

Can it show "Page 3 of 20"? Yes — choose a format that includes the total page count.

Will the numbers appear on printed copies? Yes, they are part of the page content, not a viewer overlay.
