Add Page Numbers
PDF Vault stamps page numbers onto a PDF in your browser, in the format, position and starting number you choose, without uploading the file.
A long report, contract or court filing without page numbers is hard to reference in conversation and easy to get out of order once printed. Most word processors add numbers automatically, but PDFs that were merged, scanned, or exported from elsewhere often arrive without any.
This tool draws numbers directly onto each page at export time — no reflowing, no layout risk. Pick a format like “Page 1 of 12” or a plain “1”, choose a corner or centre it, and set a starting number for documents that continue from an earlier volume.
It respects each page's own orientation, so a number placed “top right” appears top right as the page is displayed, even on a page that was scanned sideways.
How to add page numbers to a PDF
- Load the PDF you want numbered.
- Pick a number format, such as “1” or “Page 1 of 12”.
- Choose where the number sits on the page, and a starting number if needed.
- Optionally limit numbering to a page range, then download.
What you get
- Six ready formats. Plain numbers, “Page N”, “N of Total” and more, without typing a template.
- Any corner or centred. Top or bottom, left, right or centred — matches wherever your house style puts numbers.
- Custom start number. Continue numbering from where an earlier volume or appendix left off.
- Orientation-aware. Numbers land correctly on pages that are already rotated, not just upright ones.
Frequently asked questions
Can I number only some pages, like skipping a cover page?
Yes — enter a page range such as 2-40 and numbering starts from your chosen start number on page 2, leaving the cover untouched.
Will it overwrite numbers a page already has?
It adds a new number on top; it cannot detect or remove page numbers that are part of the original page content. Check a scanned or pre-numbered document first.
What does “start number” do if I number the whole document?
It sets the number on the first stamped page — useful when this file is one part of a larger, continuously numbered set.
