Cómo funciona

Adding page numbers to a PDF is an Acrobat feature most free tools either lack or gate behind an upload. This stamps them on with pdf-lib, in your browser.

1
You drop in a PDF
The page count is read locally with pdf-lib — nothing is uploaded.
2
You pick a format and position
Choose "1", "Page 1", "1 / 12", and where it sits (corner or centre, top or bottom), plus the starting number and font size.
3
Numbers are drawn on each page
pdf-lib draws the text onto every page using an embedded standard font, positioned precisely for each page's size.
4
You download the numbered PDF
The result is offered for download, with the original content untouched beneath the new numbers.

Your document is numbered entirely on your device — useful for paginating contracts, reports, and manuscripts without uploading them anywhere.
