Add Page Numbers to PDF

The Document That Has No Page Numbers

It happens in every organisation: someone assembles a 30-page report by combining several PDFs, sends it for review, and three days later the feedback arrives — "see the paragraph on the finance section" with no page reference. Nobody can find the right place quickly. A reviewer references "the third paragraph on the last page of section two" and it takes minutes to locate. Page numbers solve this entirely. Our free online PDF page numbering tool stamps a page number on every page in under a second — with full control over position, format, starting page, font size and colour. No software, no upload.

Six Positions, Three Formats — Choosing the Right Combination

Position determines where on the page the number appears. Bottom-Center is the standard footer position used in the vast majority of professional documents — it is unobtrusive and universally expected. Bottom-Right is common in academic papers and legal documents. Top-Center and Top-Right are used as running headers, often combined with a document title in a separate text pass. For format, plain numbers (1, 2, 3) are clean and minimal; Page X of Y (Page 3 of 15) is preferred for reports and proposals where the reader needs to know completeness; Roman numerals (i, ii, iii) are the traditional publishing convention for front matter — prefaces, tables of contents and dedications — before the main body begins with Arabic numerals at page 1.

Skipping the Cover Page and Front Matter

Most professional documents do not number the cover page. The Start From Page setting controls which physical page the first stamp appears on. Set it to 2 to skip the cover entirely. Set it to 4 to skip a three-page front matter section (cover, blank verso, and a copyright page, for example). Start Number independently controls what the first stamped page displays — set it to 1 so the first numbered page shows "1", or set it to 47 to continue an existing numbering sequence from a previously compiled document. These two settings work together to handle any combination of cover pages, unnumbered sections and continuation sequences.

When Page Numbers Are Not Optional

• Academic submissions: Virtually every university and journal requires specific page number positions and formats — use our Merge PDF tool to combine all chapters into one document before adding numbers so the sequence runs continuously
• Court filings and legal bundles: Courts often require every page to be numbered for record-keeping, citation and indexing purposes
• Tender submissions: Many procurement and government bid processes explicitly require numbered pages in their submission guidelines
• Technical manuals: User guides and reference documents without page numbers force readers to scroll endlessly to find referenced content
• Board packs and investor reports: Numbered pages allow board members to reference specific sections during meetings without confusion
• Books and manuscripts: Both print-on-demand and digital distribution platforms expect properly numbered pages — combine with our Watermark PDF tool to add a DRAFT stamp to review copies before finalisation

Mixed Numbering for Complex Documents

Academic and publishing conventions often require Roman numerals for front matter (i, ii, iii…) and Arabic numerals for the main body (1, 2, 3…). This cannot be achieved in a single pass, but the workflow is straightforward: use our Split PDF tool to divide the document into front matter and body sections, add Roman numerals to the front matter and Arabic numbers to the body separately, then use Merge PDF to reassemble them in order. The complete workflow takes under two minutes.

Font Size and Colour Guidelines

The default settings (11pt, dark grey) work well for most documents. For formal legal or academic documents, 10–11pt in a neutral grey (#374151 or #6b7280) is the standard. For documents intended for large-format printing (A3 or larger), increase to 13–14pt so numbers remain readable. For presentations and slide decks where page numbers should be subtle, use 8–9pt in a light grey. The preview updates live as you adjust font size and colour so you can check the result before downloading.

Private, Local Processing — No Upload Required

Every page number is stamped locally in your browser using pdf-lib. Your PDF is never uploaded to ToollyX or any external server. This is safe for adding page numbers to confidential legal filings, commercially sensitive reports, patient documents and proprietary technical manuals that must not be processed on third-party infrastructure.
