Add Page Numbers to PDF — Stamp Numbers in Any Position & Format guide

Add page numbers to a PDF in your browser: choose the position, the format (Page 3, 3 of 12, 3 / 12), the starting number and whether the cover page stays clean — then download the numbered copy.

How to use this tool

  1. Choose your PDF with the file button or drag it onto the panel. The tool reads it locally and reports how many pages it found.
  2. Pick a position: bottom centre is the classic choice, but bottom-left, bottom-right and the three top positions are all available for documents whose margins are already busy.
  3. Choose the number format — plain number, “Page X”, “X of Y” or “X / Y” — then set the starting number (useful when this file continues another document) and the font size.
  4. Decide whether the first page gets a number. Covers, title pages and separator sheets usually look better unnumbered; the count still starts from your chosen start number on the first stamped page.
  5. Click Add page numbers and save the downloaded copy. Your original file is never changed.

A worked example

A 12-page report exported from a word processor often arrives with no numbers at all because the author relied on the app’s viewer. Run it through with format “Page X of Y”, bottom centre, starting at 1 and the first page skipped, and the printed copies suddenly have a cover plus eleven numbered pages anyone can reference in a meeting — “see page 7” works again.

How it works

The tool opens the PDF with a document library in your browser and, for every page, draws the formatted number as real text at the position you chose, measured from the page’s own width and height so portrait and landscape pages both land correctly. The shade slider sets the text colour between black and light grey. Nothing is uploaded: the file is read, stamped and saved entirely on your device.

Frequently asked questions

Which format should I choose?

“X of Y” is the most helpful for readers because it shows both position and length, and it is what most business documents use. Plain numbers suit formal reports and books. Pick the style once and stay consistent across a document set.

Can numbering start from a page other than 1?

Yes — set the starting number. If this PDF is part 2 of a document and part 1 ended at page 40, start at 41 and the sequence continues seamlessly.

Can I skip more than the first page?

Only the first page can be skipped in this tool. For front matter of several pages, split the file, number the main section, then merge the parts back together with our Merge PDF tool.

Does it work on scanned PDFs?

Yes. The numbers are added as a new text layer over whatever the page contains, scanned image or born-digital text, so scans number exactly like any other page.

Is my file uploaded?

No. The PDF is opened and stamped in your browser and the result downloads straight from the page. Nothing leaves your device.
