Add Page Numbers to PDF

How to use this tool

1. Upload a PDF. A preview of the first page appears with the number already placed.
2. Choose where the number goes (top or bottom, left, centre or right) and the format, for example 'Page 1 of 10'.
3. Optionally set the starting number, skip the cover page, and adjust the font, size, colour and margin.
4. Click 'Add page numbers and download' to save the numbered PDF.

About this tool

Page numbers are the first thing a reader looks for in a long report, a thesis, a contract bundle or a printed handout, and they are often missing from PDFs that were merged together or exported from a tool that never added them. This tool stamps them onto every page of an existing PDF, without changing anything else. You choose one of six positions (top or bottom, at the left, centre or right) and one of four formats: a bare number, "Page 1", "1 of 10", or "Page 1 of 10". The total is calculated for you. The starting number can be anything, which is useful when a PDF is one chapter of a larger document and should start at, say, 47. Ticking "Skip the first page" leaves a cover or title page blank and starts the count on the page after it. The preview is the real output, rendered from the actual numbered page, so what you see is exactly what you will download. The font, size, colour and distance from the edge are all adjustable. Numbers are drawn as genuine PDF text on top of each page with pdf-lib. The original content is untouched: text stays selectable, nothing is re-compressed, and the file size barely changes. Pages that were saved rotated, which is common with scanned landscape pages, are handled properly, so the number still appears upright at the edge you chose rather than sideways. Everything happens in your browser. The PDF is never uploaded, which matters when the document is a legal bundle or a medical record.
