How do PDF Bookmarks (Outlines) work in e-readers & browsers?
PDF bookmarks (technically called PDF Outlines) act as a clickable side-panel table of contents. When readers open your PDF in Adobe Acrobat, Foxit Reader, Apple Books, Chrome, or Edge, they can instantly jump to specific chapters or subsections without manual scrolling.
What is the difference between flat and hierarchical bookmarks?
A flat outline lists every item at the top level. A hierarchical outline nests sub-chapters (Level 2) and detailed sections up to Level 10 under main headings. You can collapse or expand sub-levels in e-readers to keep long documents organized.
Is my PDF uploaded to any server?
No. 100% Privacy Guaranteed. All PDF reading, rendering, and outline compilation take place locally inside your browser using HTML5 Web APIs and WebAssembly binaries. Your files never leave your computer or touch RiazHub servers.
Does this tool support Arabic, Urdu, or Right-to-Left (RTL) titles?
Yes! Our engine encodes bookmark titles using 16-bit UTF-16BE PDF Hex strings, ensuring full support for Arabic, Urdu, Hebrew, Persian, CJK, and mathematical symbols without character corruption.
