What is the Add Page Numbers to PDF tool?
This tool stamps sequential page numbers onto every page of a PDF, entirely in your browser using the pdf-lib library — your file is never uploaded to any server. You control where the numbers appear (six corner and center positions, top or bottom), the format (plain numbers, "Page X", or "X of Y"), the starting number, and the font size, so the result can match the style of the document it's going into.
How to Use It
Select your PDF file, then choose a position, format, starting number, and font size from the dropdowns that appear once the file loads. Click Add Page Numbers, and the tool stamps every page and generates a new file ready to download — the original upload is never modified, and processing finishes in a couple of seconds even for longer documents.
When to Use It
Use it for academic papers, legal filings, reports, and manuscripts that require page numbers, or any printed document you want readers to be able to reference and reorder correctly if the pages get shuffled. It's also useful for numbering scanned documents that never had page numbers to begin with, or renumbering a document that changed length after edits.
Who Benefits
Students formatting theses and essays, legal and administrative staff preparing filings, authors assembling manuscripts, and office workers finalizing reports before printing or distribution can add consistent, correctly formatted page numbers without touching a word processor.
