Add Page Numbers to PDF

Add page numbers to any PDF: pick the corner or center, choose a format like “Page 3 of 12”, set the starting number and font size, and download. Perfect for reports, theses and court bundles. Numbering happens locally in your browser — the document is never uploaded.

Examples

Input
thesis.pdf, bottom center, "Page N of T"
Output
thesis-numbered.pdf with “Page 1 of 142” on every page

How it works

A number is drawn on every page in grey type, 28 points in from the edge, at the position you pick: top or bottom, and left, centre or right.

“Start at” sets the number on the first page, which is useful when the file is one chapter of a longer document. Every page is numbered, so a cover page cannot be skipped. The number is drawn over whatever is already there; if your pages have a footer in the same spot, pick a different corner.

Frequently asked questions

Yes. Set any starting number — handy when the file is one chapter of a larger document or when the cover page should not be page 1.

Numbers sit in the page margin (about 1 cm from the edge). On pages with unusually tight margins they may overlap — check the preview page after download.

No. Numbering runs entirely in your browser using pdf-lib — the document never leaves your device.
