FAQ
- What is a PDF outline? The outline (also called document outline or bookmarks) is a tree of titled entries that many PDF viewers show in a sidebar, letting readers jump between sections.
- Why is my outline empty? The PDF was probably saved without outline entries — this is common when exporting from basic tools or scanners. The outline must be explicitly created by the authoring software.
- Is my file uploaded anywhere? No — outline extraction runs entirely in your browser.
