About Add Page Numbers to PDF

Add Page Numbers to PDF is a free, private tool that stamps a running page number onto every page of a PDF document directly inside your web browser. Whether you are finishing a contract, assembling a court filing, printing lecture notes, submitting a manuscript, or handing over a report, numbered pages make a document easier to reference, review, and reassemble if the printout is ever dropped or shuffled. Many PDFs arrive without any numbering at all — especially files that were scanned, exported from slides, or merged together from several sources — and adding numbers by hand in a full editor is slow and fiddly. This tool does it in a single pass across the whole document.

You control exactly how the numbers look and where they sit. Position lets you place the number in any of six spots: bottom center, bottom right, bottom left, top center, top right, or top left — the two most common choices for print being bottom center and bottom right. The Format option decides the wording: a plain number like 1, 2, 3; a 'N of total' style such as '1 of 12' that tells the reader how much is left; or a labelled 'Page 1, Page 2' style. The Start number field sets the first value, which is useful when your document is one section of a larger work, when a cover page should stay unnumbered in spirit, or when you simply want to begin counting from a specific figure. A font size control lets you make the numbers as discreet or as prominent as you need, and every number is drawn in clean, universally supported Helvetica with a consistent half-inch margin from the page edge so nothing crowds the content.

The same numbering scheme is applied uniformly to all pages in one operation, so a fifty-page file is numbered just as quickly as a two-page one. The tool measures the exact width of each number so that right-aligned and centered placements line up precisely regardless of how many digits the number has, and it positions text correctly against the PDF's bottom-left coordinate system so numbers never spill off the edge of the page.

Privacy is built into how the tool works. Your PDF never leaves your device. When you pick a file, it is read into memory and processed locally using JavaScript running in your own browser; there is no server upload, no cloud storage, and no logging of your document contents. That makes it safe for confidential contracts, medical records, financial statements, and any other sensitive material, because the bytes stay on your computer from start to finish. When numbering finishes, the tool builds a new PDF and offers it as a direct download link, so you keep a freshly numbered copy while your original stays completely untouched. Because everything runs client-side, the tool is fast, works offline once the page has loaded, and costs nothing to use. Password-protected or corrupted PDFs cannot be read without their password and are reported clearly so you can unlock them first.

Frequently asked questions

Is my PDF uploaded to a server?
No. The file is read and numbered entirely inside your browser using JavaScript. Nothing is uploaded, stored, or sent anywhere, so confidential contracts, records, and statements stay private on your own device from start to finish.
Can I start numbering from a page other than 1?
Yes. The Start number field sets the value printed on the first page, and every following page counts up from there. So if you set it to 5, the first page shows 5, the next shows 6, and so on — handy when the document is a section of a larger work.
Where can the page number be placed, and what formats are available?
You can place the number in six positions: bottom center, bottom right, bottom left, top center, top right, or top left. Three formats are supported — a plain number (1, 2, 3), a 'N of total' style (1 of 12), and a labelled style (Page 1, Page 2). The same choice is applied to every page.
Will adding numbers change or damage my original file?
No. The tool builds a brand-new PDF with the numbers stamped on and offers it as a separate download, leaving your original file completely untouched on your device. The numbers are drawn in Helvetica with a consistent margin so they sit cleanly clear of your content.
