Create Roman-numeral front matter, restart chapter numbering, add prefixes, or restore standard labels without changing printed page artwork.
Page labels change viewer navigation, thumbnails, and page lookup. They do not paint text onto the page itself.
Use Roman numerals for front matter, decimal numbers for chapters, letters for appendices, and prefixes for exhibits.
The label tree is written into a new browser-generated PDF. Your original document is never modified or uploaded.
Check access, supported files, limits, and processing before choosing a document.
The core task does not require an account.
PDF page labels are navigation names stored separately from printed page content. A viewer can show front matter as i, ii, iii, restart the main document at 1, label appendices A, B, C, or display identifiers such as EX-1, while the underlying page order stays unchanged.
PDF Page Labels is a browser-based tool that lets you set Roman numerals, prefixes, letters, and numbering ranges. Choose PDF, use the controls above to configure the result, then download or use the resulting PDF. The core workflow runs locally in your browser without an application document-processing request.

EditPDF AI loads the standards-based PageLabels number tree into a range editor. Each range can choose decimal, Roman, alphabetic, or prefix-only labels, an optional prefix, and a starting number. Saving creates a new PDF with a rebuilt number tree and does not rasterize or repaint any page.
Common ways people use this tool in real documents and day-to-day workflows.
Label covers, front matter, chapters, indexes, and appendices so viewer navigation matches the document structure.
Create exhibit, schedule, disclosure, and attachment labels with prefixes and independent numbering restarts.
Use Roman-numeral preliminary pages and restart decimal numbering at the beginning of a thesis, paper, or report.
Align PDF viewer navigation with visible page references without altering page content or image quality.
Set Roman numerals, prefixes, letters, and numbering ranges.
Accepts PDF and produces PDF. Up to 100 MB and 2,000 pages
Core tool with browser-based document processing.
Select one PDF up to 100 MB and 2,000 pages. Existing custom page-label ranges are read locally from the PDF number tree.
Choose where each range begins, select decimal, Roman, letter, or prefix-only style, then set an optional prefix and starting value.
Review the navigation labels for individual PDF pages, then download a new file with the rebuilt label tree. Page artwork remains unchanged.
Confirm that your file is supported and understand how this tool handles document data.
Page-label parsing, previews, number-tree reconstruction, and PDF generation happen locally in your browser without an application document-processing request.
Open this comparison if you are deciding between the browser workflow and a manual process.
Guess at how a PDF viewer will number your front matter and appendices.
Define exact Roman, decimal, letter, or prefix ranges for each section.
Reprint pages just to change how they're labeled in a viewer's panel.
Update navigation labels without touching page artwork at all.
Use desktop publishing software for a metadata-only change.
Rebuild the label number tree entirely in the browser.
