How to roman numeral page numbers in a pdf
- Step 1Decide where Roman numbering really belongs — If your submission requires
i, ii, iiion front matter, set that in Word (Layout → Breaks → Section, then Page Number Format →i, ii, iii) or LaTeX (\pagenumbering{roman}then\pagenumbering{arabic}). Those tools own section-based numeral styles. Export the finished, correctly-numbered document to PDF — you won't need a stamping step at all. - Step 2Use the JAD tool for Arabic numbering on a PDF you can't re-author — If you only have a finished PDF and need Arabic page numbers added (the body, an appendix, a scanned report), open PDF Add Page Numbers. Accept that the output will be
1, 2, 3— neveri, ii, iii. - Step 3Set position and font size — Choose a Position (bottom-centre is the academic norm) and a font size (10 pt default; 11–12 pt for double-spaced theses). Helvetica is the only typeface — if your style guide mandates a serif numeral, that has to come from your authoring tool.
- Step 4Set the starting number — Start from sets the first page's printed number. If you're numbering only the body and want it to read
1, the body must be its own PDF starting at the first body page — because the tool numbers every page in the file it's given, including any front matter present. - Step 5Apply and check against your submission rules — Stamp the numbers and open the result. Verify the digits, position, and first-page number against your institution's e-thesis formatting checklist before you submit.
- Step 6Assemble mixed front matter + body if needed — If front matter must be Roman and body Arabic, produce each part with the correct numbering in your authoring tool (or stamp only the Arabic body here on its own PDF), then join the parts with PDF Merge.
Roman vs Arabic — what's supported here
A direct map of common front-matter numbering needs to what the JAD page-numbers tool can actually do.
| You want | Supported by this tool? | Where to do it |
|---|---|---|
Lowercase Roman (i, ii, iii) | No | Word section format i, ii, iii, or LaTeX \pagenumbering{roman} |
Uppercase Roman (I, II, III) | No | Word I, II, III format, or LaTeX \pagenumbering{Roman} |
Arabic (1, 2, 3) on every page | Yes | This tool — Position + Start from + Font size |
| Arabic body starting at 1, no front-matter numbers | Partially — number the body as its own PDF | Split off the body, number it here, re-merge |
| Roman front matter + Arabic body in one file | No (not in a single pass) | Set both in your authoring tool, or number parts separately and merge |
The tool's actual options
Everything the page-numbers UI exposes — none of it includes a numeral-style choice.
| Control | Values | Default |
|---|---|---|
| Position | 6 choices: top/bottom × left/center/right | bottom-center |
| Start from | Integer ≥ 1 (Arabic) | 1 |
| Font size | 6–72 pt, Helvetica only | 10 |
| Numeral style | Not a control — Arabic integer is hard-coded | — |
Cookbook
Because Roman numerals aren't available, these recipes show the realistic paths for formal documents: clean Arabic numbering here, and where true Roman numbering must come from.
Arabic body numbering for a thesis (the supported path)
Your front matter is already correctly Roman-numbered in your exported PDF (set in Word/LaTeX). You only need Arabic numbers added to a body section you assembled separately.
Input: body-only PDF (introduction onward) Position: bottom-center Start from: 1 Font size: 11 Page (1) → 1 Page (2) → 2 Page (3) → 3 … → Merge with the Roman-numbered front matter afterward.
What you'd get if you 'just numbered' the whole thesis
Dropping a full thesis (front matter + body) into the tool numbers everything in Arabic — the front matter gets 1, 2, 3 too, which fails the convention.
Input: full thesis, 8 front-matter pages + 120 body Start from: 1 Page (1) → 1 ← should be i Page (2) → 2 ← should be ii … Page (9) → 9 ← should be 1 (first body page) Wrong for academic submission — do not use this way.
True Roman front matter in Word (do this, not the tool)
The correct, standards-compliant way to get i, ii, iii on front matter and 1, 2, 3 on the body — set in the authoring tool, then export to PDF.
Word: 1. Place cursor at end of front matter → Layout → Breaks → Section Break (Next Page). 2. Front-matter section: Insert → Page Number → Format → 'i, ii, iii' → Start at i. 3. Body section: unlink from previous → Format → '1, 2, 3' → Start at 1. 4. Export as PDF — numbering is baked in.
True Roman front matter in LaTeX
The LaTeX equivalent — two commands switch the numeral style at the body boundary.
\frontmatter % or:
\pagenumbering{roman} % i, ii, iii on front matter
... title, toc, preface ...
\mainmatter % or:
\pagenumbering{arabic} % resets to 1 at first body page
... chapters ...Uppercase vs lowercase Roman — neither is in this tool
A reminder that the earlier claim of an upper/lower Roman toggle was incorrect. The tool has no numeral-style control at all.
Lowercase i, ii, iii → set in Word/LaTeX (not here) Uppercase I, II, III → set in Word/LaTeX (not here) This tool always emits: 1, 2, 3 (Arabic, grey Helvetica)
Edge cases and what actually happens
Looking for a Roman numeral setting
Not availableThere is no numeral-style control. The engine builds each label as an Arabic integer from the page index plus your Start from value. No setting, advanced option, or Pro toggle produces i/ii/iii. For Roman numbering, use your authoring tool's section page-number format and export to PDF.
Uppercase vs lowercase Roman toggle
Not availableBecause Roman numerals aren't supported at all, there is no choice between i, ii, iii and I, II, III. Any earlier wording suggesting both formats were available was inaccurate. The only style the tool emits is Arabic.
Numbering only front matter with Roman, body with Arabic in one pass
Not availableThe tool applies one Arabic sequence to every page of the file. Mixed numeral styles in a single pass aren't possible. Produce each section with correct numbering in your authoring tool, or stamp only the Arabic body (as its own PDF) here and merge it with separately-prepared Roman front matter.
Front matter ends up with Arabic numbers
By designIf you stamp a file that still contains front matter, those pages get Arabic numbers too — every page is numbered. To avoid it, separate the body before stamping. The Start from value cannot make the tool skip the front-matter pages.
Style guide requires a serif numeral
Helvetica onlyMany academic style guides expect the page number to match the body serif typeface. This tool always stamps Helvetica (sans-serif). If a serif numeral is mandatory, it must be set in your authoring tool's footer, not added here.
E-thesis platform accepts the numbered PDF
SupportedWhen you do use the tool for an Arabic body, the numbers are stamped as static page content — fully compatible with university e-thesis upload systems, which treat the PDF as a flat document. The compatibility concern is the numeral *style* (must be Roman where required), not the file format.
Start from must be ≥ 1
Min 1You cannot use a 0 or negative Start from to offset front matter behind the body. The first stamped page always shows at least 1. Control which pages are numbered by controlling which pages are in the file you stamp.
Re-stamping a partly-numbered manuscript
Double numbersIf a draft already has numbers (Roman from Word on front matter, say) and you stamp Arabic here, both appear — the existing numbers are part of the page content and aren't replaced. Stamp only pages that have no existing numbers, or fix numbering entirely in the authoring tool.
Frequently asked questions
Can I use uppercase Roman numerals (I, II, III)?
No. The tool does not produce Roman numerals in any case — there is no i, ii, iii option and no I, II, III option. It stamps Arabic integers only. For uppercase Roman, use your word processor's I, II, III page-number format or LaTeX's \pagenumbering{Roman}, then export to PDF.
How do I get i, ii, iii on my front matter and 1, 2, 3 on the body?
Set it in the authoring tool, not here. In Word, insert a section break between front matter and body, format the front-matter section as i, ii, iii and the body as 1, 2, 3 starting at 1. In LaTeX, use \pagenumbering{roman} for front matter and \pagenumbering{arabic} for the body. Export the result to PDF — the mixed numbering is baked in.
Can I do both Roman and Arabic numbering in one pass?
No. The tool applies a single Arabic sequence across every page. There's no per-section or per-range numeral control. If you only have PDFs, prepare the Roman front matter and Arabic body as separate files (numbering the Arabic body here is fine), then combine them with PDF Merge.
Will my thesis submission system accept numbers from this tool?
The file format is fine — numbers are stamped as static page content that any e-thesis platform accepts. The catch is the *style*: if your institution requires Roman front matter, Arabic-only numbers from this tool will fail the formatting check. Use it only for the Arabic portions, and set Roman numbering in your authoring tool.
Is there a Pro version that adds Roman numerals?
No. Roman numeral support is not gated behind a tier — it simply isn't implemented in the page-numbers engine. Pro raises file-size and page limits, but the numeral style stays Arabic on every tier.
What if I only have a finished PDF and can't re-author it?
Then your realistic options are: (1) accept Arabic numbering from this tool; (2) add the page numbers in a full PDF editor that supports Roman section numbering; or (3) extract the body, number it here in Arabic, and merge it back with the front matter. There's no in-browser way to convert an existing PDF's numbers to Roman.
Can the tool restart numbering at 1 for the body section?
It can stamp a body that starts at 1 — but only if the body is its own PDF. The Start from value sets the first page's number for whatever file you give it; it cannot detect a section boundary inside a single file and restart. Split off the body first.
What font and colour are the Arabic numbers?
Helvetica, in soft grey (rgb(0.3, 0.3, 0.3)), 30 pt from the chosen edge. None of these are configurable. Only the font *size* (6–72 pt) and position can change. A serif or black numeral has to come from your authoring tool.
Why does the tool number my contents and preface pages?
Because it numbers every page in the file — there is no skip. Front-matter pages present in the file receive Arabic numbers like everything else. To keep them unnumbered (or Roman), they must not be in the file you stamp, or the numbering must be set upstream in your authoring tool.
Is converting a PDF to Roman numbering possible with any JAD tool?
No. None of the PDF tools convert existing page numbers between numeral systems. The page-numbers tool stamps Arabic; PDF Bates Numbering stamps prefixed zero-padded Arabic for legal discovery. Neither produces Roman numerals.
Is my manuscript uploaded anywhere?
No. All processing is in your browser via pdf-lib — the manuscript text never leaves your device. Only an anonymous usage counter is recorded when signed in. This is the same privacy model whether you're numbering a public report or an embargoed dissertation.
What's the difference between this and Bates numbering for a formal document?
Page numbers (this tool) are a navigation aid: bare Arabic integers, grey Helvetica, six positions. Bates numbering is for legal discovery: a fixed prefix plus a zero-padded number (e.g. EXH-000001) in bold black Courier at a corner. Neither is Roman, but Bates is the one to reach for when you need a prefixed, padded sequence.
