FAQ
Q1: What are PDF bookmarks used for?
PDF bookmarks (also called outlines or table of contents) let you navigate within a PDF document. Clicking a bookmark jumps directly to the relevant page. They're especially useful for long documents, manuals, reports, and textbooks.
Q2: Will adding bookmarks increase file size?
The data added is very small (typically a few KB). Bookmarks only store the title text, page references, and hierarchy level β they don't add any page content.
Q3: Will my PDF file be uploaded to a server?
Absolutely not! All processing happens locally in your browser using the pdf-lib library. Your PDF data is never uploaded to any server β complete privacy and security.
