Add page numbers to a PDF — choose the position on the page, the number format, and which number to start from. Perfect for reports, theses and merged documents that lost their numbering. The numbering is stamped in your browser, so the file is never uploaded.

Frequently asked questions

Open your PDF, pick where the numbers go (such as bottom center or bottom right), choose a format like "1" or "Page 1 of 10", set the starting number, and download the numbered file.

Yes. Set any starting number — handy when a document is part of a larger set, or when a cover page means the first numbered page should be 2.

No. The numbers are stamped onto the pages entirely in your browser, so the document stays on your device.

Documents assembled from multiple sources — merged PDFs, scanned paperwork, exported slides — often have no numbering or inconsistent numbering. Adding a uniform sequence makes the document citable and easy to navigate in print.
