About Add page numbers
Long PDFs need page numbers — for navigation, for citations, for printing. Add Page Numbers stamps a clean numeric overlay on every page exactly where you want it.
Pick from six positions (top / bottom, left / centre / right), choose your format ("1", "Page 1", "1 of 24"), and optionally start from a number other than 1 (for cover pages, table of contents, etc).
How Add page numbers works
Three steps. Done in seconds.

Add page numbers — frequently asked questions
Everything you need to know.
How do I write the format string?
{n} = current page number, {total} = total pages. Examples: "{n}" -> 1, 2, 3 ... ; "Page {n}" -> Page 1, Page 2 ... ; "{n} of {total}" -> 1 of 24, 2 of 24...
Can I start numbering from a number other than 1?
Yes. Use the "Start numbering from" field. If your PDF has a 2-page cover, set start = 1 and the first numbered page (actual page 3) will show 1.
Can I skip the cover page?
Yes — extract pages 3-end with Extract Pages first, add numbers, then merge the cover back on with Merge PDF.
What font is used?
Helvetica 10pt by default — clean and universally readable. Custom fonts are on our roadmap.
Will adding page numbers grow the file size?
Negligibly. A few KB of overlay per page; usually under 1% of the source file size.
