Why Add Page Numbers to a PDF?

Page numbers are standard in any multi-page document that will be printed, shared, or presented. They're essential when:

  • Referencing specific pages in a document during a meeting or discussion
  • Printing a document that will be physically reviewed or bound
  • Submitting a document where specific page references are required (legal filings, reports)
  • Combining multiple PDFs where each section has its own numbering
  • Re-numbering after removing or adding pages to an existing document

Number Format Options

  • Arabic numerals (1, 2, 3) — standard for body content
  • Roman numerals (i, ii, iii) — traditional for front matter (preface, table of contents)
  • Uppercase Roman (I, II, III) — formal document convention
  • Alphabetical (A, B, C) — used for exhibit numbering in legal documents
  • Page X of Y — shows total pages, common in professional reports

Position Options

Page numbers can be placed in any of six positions on each page:

  • Bottom centre — the most common position for reports and books
  • Bottom right — common in business documents and contracts
  • Bottom left — used for alternating pages in book-style documents
  • Top centre, top right, top left — for header-positioned numbering

After Adding Page Numbers

If you need to add a table of contents referencing page numbers, edit the document inconvert it to Word first, add the table of contents, then convert back to PDF. The page numbers stamped by this tool will be correctly preserved.

For documents with existing wrong page numbers, use Redact PDFto remove the old numbers first, then add correct ones with this tool.
