Insert page numbers into a PDF by loading the document, choosing a placement and format, setting the first value and font size, and applying one consistent scheme to every page. The Add Page Numbers to PDF tool is designed for that exact task. It works entirely in your browser: the PDF is read locally with JavaScript, and the document is never uploaded, stored, or sent anywhere. Once the tool page has loaded, the numbering process can also run offline. There is no signup, and the tool is free to use. Instead of modifying the file in place, it creates a new PDF with numbers stamped onto every page and offers that copy as a direct download. Your original remains untouched on your device. You can select from six page positions, use a plain number, an "N of total" style, or a labelled "Page N" style, and choose where the count begins and how large the text appears. The tool uses Helvetica and keeps each number within a consistent half-inch margin, giving every page the same clean treatment.
The output the browser workflow creates
Each selected PDF produces a new, numbered document with a running page number on every page. The same numbering scheme is applied uniformly across the full file in one operation, so you do not need to repeat the task separately for each page. This makes page numbers useful for contracts, court filings, lecture notes, manuscripts, and reports. Numbered pages are easier to reference during review, and they help a reader reassemble a set of printed pages if the pages are dropped or shuffled.
One important boundary is that the defined tool stamps every page in the selected file. Its controls do not include selecting individual pages or skipping a cover page. The starting-number field changes the first value that appears; it does not change which pages receive a number. If the first page is a cover that you want visually unnumbered, account for that before using the all-pages result.
Match the label to the reader
The format setting controls the wording around each number. Choose the option that gives readers the clearest reference without making the page unnecessarily busy.
| Format | Example appearance | Useful when |
|---|---|---|
| Plain | 1, 2, 3 | You want compact numbering and the surrounding document already makes the page order clear. |
| N of total | 1 of 12 | Readers benefit from seeing the full sequence and their progress through the document. |
| Page N | Page 1, Page 2 | You want the reference to be explicitly labelled in a contract, report, manuscript, or similar document. |
Your format choice is applied to every page, not just selected pages. The plain style takes up the least visual space, while the other two styles make the page reference more explicit. The "N of total" style is particularly helpful when someone may lose track of a long document, and the labelled style can make printed pages easier to identify. These options cover simple counts and common labelled or progress-aware formats without requiring a separate editing application.
Place stamps away from content
Position determines where each number appears. There are six supported locations, giving you room to match the stamp to the document's layout and printing needs.
| Position | Placement |
|---|---|
| Bottom center | Centered along the lower margin |
| Bottom right | Right end of the lower margin |
| Bottom left | Left end of the lower margin |
| Top center | Centered along the upper margin |
| Top right | Right end of the upper margin |
| Top left | Left end of the upper margin |
Bottom center and bottom right are common choices for printed documents because they keep the reference near the edge without placing it in the main reading area. Top positions can suit material that already uses the bottom of the page for footnotes, captions, or other content. Every stamp uses Helvetica with a consistent half-inch margin from the page edge. The tool also measures the width of the numbers, allowing centered and right-aligned placements to remain precise as the number of digits changes.
Insert the numbers into the PDF
Complete the task directly in the browser with these steps.
- Load the PDF. Click Browse PDF and choose the document you want to number, or drag the PDF onto the page. The file is read locally in your browser. A password-protected PDF needs its password before it can be read, while a corrupted file is reported clearly so you can resolve the issue before trying again.
- Choose a position. Select bottom center, bottom right, bottom left, top center, top right, or top left. Pick one location that leaves the main page content clear and suits how the document will be read or printed.
- Choose a number format. Select a plain number, the "N of total" style, or the labelled "Page N" style. The selected format will be used consistently on every page.
- Set the starting number and font size. Enter the first value to display in the starting-number field. This is useful when the PDF is one section of a larger work. Then choose a font size that is discreet enough for the margin or prominent enough to stand out.
- Apply the numbering and download. Click Add page numbers. When processing finishes, use the result link to download the numbered copy. The same numbering scheme is stamped on every page, while the original PDF stays unchanged on your device.
Privacy and file-access boundaries
The PDF is read into memory and processed locally using JavaScript running in your browser. There is no server upload, no cloud storage, and no logging of your document contents. The bytes stay on your computer from selection through processing, which makes the workflow suitable for confidential contracts, medical records, financial statements, and other sensitive material. Because the tool works client-side, it can also operate offline after its page has loaded.
The output is a new PDF rather than an in-place edit. That separation keeps the source file intact and gives you a distinct download containing the numbered pages. No account is required. The remaining access limitation is the document itself: a password-protected or corrupted PDF cannot be processed as an ordinary readable file, and the tool reports the problem clearly so you can unlock or otherwise resolve it first.
Review the downloaded document
After downloading the result, open it and confirm that the first page shows the intended starting value, the following pages count upward, and the chosen wording appears correctly. Check that the position does not compete with important content and that the font size remains readable. The stamp uses a fixed margin, but your document's own layout still determines how visually prominent it appears. If a setting is wrong, adjust the relevant control and run the process again with the unchanged original file.
Match the setup to the document's purpose. For a report or manuscript, the "N of total" format gives readers a clear sense of the document's length. For a contract, filing, or formal handover, a labelled "Page N" style can make references more explicit. When the file belongs to a larger work, set the starting number to the first value expected for that section. For printed notes or reports, bottom center and bottom right are practical positions to consider. After those choices are checked, the downloaded copy is ready to use while your original remains available separately.
