工作原理
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.
- 1You drop in a PDFThe page count is read locally with pdf-lib — nothing is uploaded.
- 2You pick a format and positionChoose "1", "Page 1", "1 / 12", and where it sits (corner or centre, top or bottom), plus the starting number and font size.
- 3Numbers are drawn on each pagepdf-lib draws the text onto every page using an embedded standard font, positioned precisely for each page's size.
- 4You download the numbered PDFThe 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.
