Add page numbers to a PDF

Number the pages of any PDF before printing or submitting it: pick one of six positions, the starting number, the font size, and plain or "Page X of Y" formats. Rotated scans and odd page sizes are handled correctly, and the whole job runs in your browser — the document is never uploaded.

Position on the page

12 pt suits most documents; large print sits comfortably at 16–18 pt.

Preview of the stamp: {{ sampleLabel }} in Helvetica. Rotated and odd-sized pages are handled — the number always lands where the reader sees it.

From a free tool to your own software

Software for legal compilations, tender bids and formal reports

Page numbers matter most when someone else will cite them: a judge turning to a page in a paperbook, a tender committee checking an index, an examiner reviewing a thesis. Law firms, bid consultants and report-heavy businesses often assemble these by hand, and one late annexure throws every reference out. Software that builds the document, the numbering and the index together keeps them in step.

  • Court paperbook and compilation builders

    Pick the pleadings, annexures and orders, and the system assembles them in sequence, numbers every page and generates an index whose page references update when a document is added.

  • Tender bid preparation software

    Map each document to the bid's requirement list, track what is still missing, and produce a numbered, indexed submission set your team can check line by line before the deadline.

  • Automated report generation

    Valuation, inspection or audit reports generated from your data in a consistent template, with numbered pages, headers, a contents page and your letterhead applied every time.

  • Thesis and dissertation submission portals

    Students upload their final document, the portal checks margins, pagination and other formatting against your guidelines, and supervisors approve it before it goes to examiners.

Who we build this for: Law firms, advocates' chambers, tender consultants, valuers, auditors and universities.

This tool runs entirely in your browser. The team that built it designs custom software for businesses and runs DigiSign, our own signage platform, in production.

Questions people ask

How do I add page numbers to a PDF for free?

Drop the file here, pick a position and format, and download — no signup, no watermark, and the numbering is stamped into the file itself so it prints everywhere.

Can the numbering start from a number other than 1?

Yes. Set any starting number — useful when a cover page or an earlier volume comes before this file. "Page X of Y" continues the count, so starting at 5 on a 10-page file reads "Page 5 of 14".

Where can the numbers be placed?

Six positions: top or bottom, each in left, centre or right. Bottom centre is the convention for reports; top right suits legal bundles.

What happens on rotated or unusual page sizes?

The tool reads each page's stored rotation and true dimensions, and places the number relative to the page as a reader sees it — so a landscape scan gets its number at the visual bottom, not off the edge.

Is my document uploaded?

No. The stamping runs entirely inside your browser with an open-source PDF library served from this site; nothing is transmitted anywhere.

Will the numbers cover my content?

The stamp sits in the margin area, about a centimetre from the page edge. If your document prints edge to edge, pick the corner with the most white space and a smaller font size.
