Add Page Numbers to a PDF

What adding page numbers to a PDF is for

A lot of PDFs arrive without any numbering — a scanned contract, a chapter someone exported from Word, a stack of pages you merged together from different files. Once a document runs past a few pages, that becomes a real problem. You can't tell a colleague to "check page 14," a court clerk may reject a filing that isn't paginated, and a printed handout that gets dropped on the floor is impossible to put back in order. This tool stamps a clean, consistent number onto every page so the document can be referenced, cited, and reassembled.

When you'd reach for it

Common cases: legal and court filings that require numbered pages, academic papers and theses, business proposals and reports, meeting handouts, self-published book manuscripts, and any PDF you've stitched together from several sources. It's also handy after you've reordered or combined pages, because the original numbering (if any) no longer matches the new order.

A quick tip on starting numbers

The starting-number setting matters more than people expect. If your PDF has a cover page and a table of contents that shouldn't count, you may want the body to begin at "1" a few pages in — so you'd set the start so the first real page reads the way you intend. Setting the start to a higher value is also useful when a document is one part of a larger set, like a second volume that should continue from page 240.

How to use it

1. Open your PDF with the file picker. It loads straight into this page in your browser.
2. Choose where the number sits — for example a bottom-center or bottom-right corner, the most common spots for printed documents.
3. Set the starting number (leave it at 1 for a normal document, or bump it up to continue from another file).
4. Download the numbered PDF. The original file on your computer is untouched, so you can redo it with different settings anytime.

FAQ

Are my files uploaded anywhere?

No. The PDF is processed entirely inside your browser and never leaves your device, which matters for contracts, medical records, and other sensitive documents.

Can I skip numbering the cover page?

The simplest approach is to set your starting number so the count lines up with the page you consider "page one." If you need a truly blank cover, remove that page first, number the rest, then add the cover back.

Will it change the text or layout of my pages?

No. It only adds a small number in the position you pick. The existing content, fonts, and images stay exactly as they were.

Is it free to use?

Yes, it's free and supported by ads on the page. There's no sign-up and no watermark on your finished PDF.
