關於此工具
Add Page Labels assigns display labels to PDF pages — like roman numerals, prefixes, or section-specific numbering — without touching the physical page content. These labels are what PDF readers show instead of the raw page number, so navigation reflects the document's own structure.
Academic documents are the classic case: a front matter with i, ii, iii, then Arabic numbering restarting at 1 for the main text, and an appendix that begins again at A-1. Theses, journals, and technical manuals all need exactly this kind of sectioned numbering, and reviewers or exam boards check for it before anything is considered finished. A manual writer labels the prelude, each chapter's pages, and an index so every part reads as its own sequence.
You define disjoint ranges, so several label schemes coexist in one file, and choose numerals or prefixes for each selected span. Text and layout are untouched, and the tool writes the label structure cleanly. Processing happens locally, so drafts never leave your device. Free, no account, and precise.
Practical guidance before you use 添加頁面標籤
Best for real document workflows
Use 添加頁面標籤 when you need a quick browser-based result without creating an account or sending routine documents through an unnecessary upload workflow. Academic Thesis Formatting is a common example: Set lowercase Roman numerals (i, ii, iii) for introductory front matter and transition to decimal for main chapters.
Privacy and file handling
EasyPDFNex prioritizes local processing in your browser. That means supported PDF operations run on your device, not in a public cloud queue. For sensitive files, review the output before sharing it, close the browser tab after downloading, and avoid processing documents you are not authorized to edit.
Quality checks after processing
After you preview and download, open the result and check page order, text readability, signatures, links, and form fields. If the source file is scanned, encrypted, very large, or damaged, try a related workflow such as page numbers, organize pdf, merge pdf before repeating the task.
Start with a clean source file whenever possible. For 添加頁面標籤, the first step is usually "Upload PDF Document": Provide the target PDF document you wish to label. This simple preparation step prevents most failed exports, missing pages, and formatting surprises.
Editorial review note
This guidance is maintained by the EasyPDFNex editorial team and reviewed for practical PDF workflow accuracy. Tool pages are written to explain when a feature is useful, what to check before download, and where browser-based processing has limits.

常見問題
What are page labels vs page numbers?
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.
What happens if I leave the Page Range empty?
Leaving the page range empty causes the rule to apply globally to all pages of the document.
How are overlapping rules handled?
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.
