Add page numbers to a PDF in your browser — choose the format, position and starting number. The file is processed entirely on your device, never uploaded. Runs entirely in your browser — your numbers never leave this device.
No PDF yet. Choose one above — a page number is stamped onto every page of the copy you download; your original file is never changed.
| Choice | Options | Notes |
|---|---|---|
| Format | n · Page n · n of N · - n - | “n of N” prints the total, e.g. page 3 of a 12-page file reads “3 of 12” |
| Position | Bottom centre · bottom corners · top centre · top corners | Bottom centre is the convention for reports and manuscripts |
| Starting number | Any whole number ≥ 0 | Start at 17 and an 8-page file is labelled 17–24 |
| Pages stamped | Every page | The label on page k is start + (k − 1) |
Your file is processed entirely in your browser and never uploaded: it is opened in memory on your own device, a number is drawn onto each page in the position and format you choose, and the stamped file is offered back as a download. Nothing reaches a server, and the tool works offline once the page has loaded. Unlike the structural tools, this one does draw on the pages — but only to add the number text; the underlying page content is not re-rendered or re-encoded, so the original text, images and vectors are untouched beneath the stamp.
Three choices define the result, and the table below lists them. The format decides what the stamp says: a bare number, “Page n”, “n of N” (where N is the document's total page count), or a number fenced with dashes. The position is one of the standard spots — bottom centre is the default readers expect, with the corners and top available. The starting number offsets the sequence: a document whose pages continue from a previous file can start at 17, so its eight pages are labelled 17 through 24 (17 + 8 − 1 = 24).
Two honest limits are worth knowing before you stamp. The numbers are drawn text, added permanently to the downloaded file — they cannot be removed later except by working from your unstamped original, so keep it. And a document that already has printed numbers in its content will end up with two sets; page numbers baked into a scan are content, and no structural tool can tell them apart from any other ink on the page.
No. The file is opened, stamped and downloaded entirely inside your browser; it never leaves your device, is never stored or logged, and the tool works with the network off.
Not from the stamped file — the numbers are drawn onto its pages permanently. Keep the unstamped original; restamping from it with different settings takes seconds.
No. The number is drawn over the page as additional text; the existing content is not re-rendered, re-encoded or moved. If a page already carries printed numbers as content, both sets will show.
The offset works through the starting number: a cover that should stay unnumbered is better handled by splitting the cover off with Split PDF, stamping the body, and merging the cover back in front — a three-step job, each step lossless.
It prints “1 of 1”. The total N is the document's real page count, counted from the file itself, never estimated.
