How PDF Page Numbering Works
AnyTool adds page numbers to PDFs by drawing text at the specified position (top/bottom, left/center/right) on each page using pdf-lib. Users configure the starting number, format, font size, and color.
How to add page numbers to a PDF?
Upload your PDF, choose the position (top or bottom, left/center/right), select a number format, and click Apply. Page numbers are added to every page — all in your browser.
