このツールについて
Add Page Labels allows you to inject custom page labeling metadata (/PageLabels) into your PDF's root Catalog dictionary. This customizes the labels displayed in professional PDF reader navigation sidebars and top page number jump panels (e.g. using Roman numerals for front matter, decimal sequences for main body, or custom prefixes such as A-0, A-1 for technical subsections).
Supports combining multiple custom rules seamlessly. Crucially, we've built a highly optimized disjoint-range slicing algorithm: even if you declare complex alternating patterns (e.g., odd pages style A, even pages style B), the tool will elegantly dissect and compose boundaries to ensure proper standard-compliant display without leaking formats into unmapped pages.
All operations are processed entirely inside your local browser sandbox, securing absolute data privacy.

Ordinary page numbers are visual text blocks rendered directly on the paper canvas (visible when printed). Page labels, however, are structural metadata injected into the PDF catalog. They control what is displayed underneath thumbnails and in the page lookup box inside software like Adobe Acrobat or Apple Preview.
Leaving the page range empty causes the rule to apply globally to all pages of the document.
Rules are evaluated sequentially in the order they are listed. If a page range of a later rule overlaps with an earlier one, the later rule takes priority and overrides the label for that page.
