How It Works
Upload a PDF and configure the page numbering settings — position, format, starting number, and font size. The tool loads your document using pdf-lib.js, adds the formatted page number text to every page, and saves the result — all in your browser.
Choose from four numbering formats: plain numbers (1, 2, 3), "Page X of Y" (professional), dashed (— 1 —), or Roman numerals (i, ii, iii). Numbers can be placed at any of six positions: top or bottom × left, center, or right.

Under the Hood
The tool uses pdf-lib's page.drawText() API to render the formatted page number at the specified coordinates on each page. Font metrics from Helvetica are used to calculate text width for center and right alignment. The numbering respects each page's orientation and dimensions.
