Use cases

When do you need page numbers?

From legal submissions to print-ready reports, page numbers are a professional requirement across many document types.

Legal filings and court documents

Courts and legal proceedings often require sequentially numbered pages. Add numbers in seconds, ready for submission.

Academic papers and theses

Universities require page numbers on dissertations and research papers. Set a custom start to skip the title page.

Business reports and proposals

Professional reports look polished with page numbers in the footer. Clients can reference specific pages during review.

Multi-section manuals

Start numbering at any number, perfect when chapters are combined after being authored separately.

Print-ready documents

Printers and binding services often require page numbers before they will process a document. Add them here without reprinting.

Contracts and agreements

Numbered pages make it easy to confirm all parties are reviewing the same version and no pages have been omitted.

How page numbering works under the hood.

The tool uses pdf-lib to load your PDF entirely in browser memory and draw text onto each page at the position you select. Numbers are rendered in Helvetica, a universally supported PDF font, so the result looks clean in every viewer.

The original page content is completely untouched. Numbers are simply drawn on top. Nothing is uploaded to a server at any point.

Common questions

Questions answered.

Does this affect existing text in the PDF?
No. Page numbers are drawn on top of existing content. The original text, images, and layout are unchanged.
Can I choose where numbers appear?
Yes. You can place numbers at the bottom center, bottom left, bottom right, top center, top left, or top right of every page.
What formats are available?
Three formats: plain numbers (1, 2, 3), "Page N" (Page 1, Page 2), or "N of Total" (1 of 10, 2 of 10).
Can I add numbers starting from a page other than 1?
Yes. Set any starting number in the Start At field. Useful for documents where the first few pages are a cover or table of contents.
Will numbers appear on every page?
Yes. The number is drawn on every page of the PDF, incrementing by 1 per page.
Can I change the font size of the numbers?
Yes. The font size control lets you increase or decrease how large the page numbers appear on each page.
Can I remove page numbers later?
Not with this tool. Once drawn, the numbers become part of the PDF content. Keep an unmodified copy of your PDF if you may need to re-number later.
Is my file uploaded to a server?
No. All processing happens locally in your browser using pdf-lib. Your file never leaves your device.
