About PDF Page Labels

PDF page labels are the page identifiers displayed in the viewer's navigation bar. In academic papers and books, it is common to use lowercase Roman numerals (i, ii, iii) for preface and table of contents, Arabic numerals (1, 2, 3) for the body, and letter prefixes (A-1, A-2) for appendices.

However, page labels can be lost or become inaccurate when merging or editing PDFs. This tool lets you configure page label style (Arabic, uppercase/lowercase Roman, uppercase/lowercase letters), prefix, and starting number for each section of your PDF.

You can define multiple label sections — for example, pages 1-4 use lowercase Roman numerals, and pages 5 onward use Arabic numbers starting from 1. The up/down buttons let you reorder sections freely, making it easy to experiment with different configurations.

All processing runs locally in the browser using pdf-lib, so your PDF data is never uploaded. Perfect for academic papers, books, manuals, and formal reports that require proper page numbering.
