Page numbers are a small detail that make a document feel finished — and a genuine problem when a printed, stapled stack of pages gets shuffled. This tool adds clean, consistently placed page numbers to every page of a PDF using pdf-lib, with a choice of position, format, and starting number, all computed and applied locally in your browser.
