Free Roman Numeral Page Numbers for PDF — Number Pages I, II, III

Theses, books, and formal reports traditionally number their front matter in roman numerals — i, ii, iii — before the body switches to arabic digits. This tool stamps clean roman numeral page numbers on any PDF: uppercase or lowercase, “Page iv” or “iv of xii” formats, your choice of position and start value. It runs entirely in your browser with pdf-lib; your document is never uploaded anywhere.

How it works

The tool loads your PDF with pdf-lib in your browser, embeds a standard font, and draws a roman numeral label (I, II, III… or i, ii, iii…) on each page from your chosen start page — skipping cover pages if you like. Numerals are computed with a classic subtractive-notation converter, so 4 becomes IV and 9 becomes IX. A new numbered copy is saved for download; the original file is untouched.

Everyday uses

• Students — number thesis front matter (abstract, contents, acknowledgements) in roman numerals.
• Authors — give ebooks and printed books a traditional front-matter feel.
• Legal & formal reports — match institutional formatting requirements for preliminary pages.
• Designers — add elegant roman numerals to portfolios and lookbooks.

Frequently asked questions

Can I mix roman and arabic numerals in one PDF?

Yes — run this tool on the front matter pages first, then use an arabic page-number tool on the body. Set “First page to number” to control where each pass applies.

What is the largest numeral supported?

The converter handles any practical page count (I up to MMMCMXCIX / 3999 and beyond).

Is my document uploaded anywhere?

Never. pdf-lib runs entirely in your browser, so your files never leave your device.
