How adding page numbers works
Adding page numbers to a PDF means stamping a running number — like 1, 2, 3 or "Page 1 of 12" — onto every page of the document, so readers can reference, cite, or navigate to a specific page. It's one of the simplest edits to a PDF, but also one of the easiest to get wrong without seeing it first: a number sitting too close to the edge, overlapping existing content, or starting from the wrong page after a cover sheet are all common mistakes.
This tool stamps the number onto every page of your PDF entirely in your browser, with a live preview of your first page so you can see the exact result before committing. Pick a format — a plain number, a number with the total page count, a labeled "Page X of Y" style, or lowercase/uppercase Roman numerals for front-matter pages like a preface — then choose where on the page it sits, its font size, color, and how far it should sit from the page edge. You can also set a custom starting number and skip a cover page so numbering begins from the content itself. If you picked the wrong setting, an "Edit settings" button takes you straight back without re-uploading the file.
Common use cases
- Numbering a report, thesis, or manuscript before printing or submission
- Adding page references to a contract or legal document so clauses can be cited by page
- Preparing a court filing or government submission that requires visible page numbers
- Numbering an eBook or manual, with Roman numerals for the preface and Arabic numerals for the body
- Labeling a scanned document with sequential page numbers for easier filing
Once the numbers are stamped, an optional step lets you add a table of contents page listing section titles and their page numbers. Nothing is uploaded to a server at any point — the PDF is read, stamped, and rebuilt entirely on your own device, and the result downloads straight to your computer, whether you're on a desktop or a phone.

Plain numbers (1, 2, 3...), "1 / 12" style with the total page count, "Page 1", "Page 1 of 12", and lowercase or uppercase Roman numerals (i, ii, iii or I, II, III) — the convention often used for a preface or table of contents before the main numbering starts.
Yes — a live preview of your PDF's first page updates as you change the format, position, font size, margin, and color, so you know exactly what you're getting before you stamp all the pages.
Yes — all three are adjustable. The margin control sets how far the number sits from the page edge, which matters if your document is already printed with tight margins or gets bound/hole-punched after printing.
Yes — toggle "Skip first page" and numbering starts from the second page instead. The starting number still applies to that second page.
Yes — after adding page numbers, you get an optional step to build a table of contents page by typing section titles and their page numbers. It's entry-based, not automatic heading detection, since reliably detecting which text is a heading from arbitrary PDF content isn't something we want to promise without it actually working well.
No — an "Edit settings" button takes you back to the configuration screen without losing your uploaded file, so you can adjust and re-run as many times as you need.
Yes — the tool runs the same PDF engine in your phone's browser as on desktop, with a layout designed for touch. Larger files just take a little longer depending on your device.
Yes, free with no sign-up, no watermark, and no page limit. Your PDF is never uploaded — it's read, numbered, and rebuilt entirely on your own device using your browser's memory, then the result downloads straight to your computer.
