What are bookmarks for?

They’re the outline shown in a PDF reader’s side panel: one click takes you to the chapter. Essential in a long report, a thesis, an application pack.

How are bookmarks built from headings?

The tool reads the document’s text, spots headings by their size, and turns them into bookmarks nested by level. You can then fix them one by one.

Is my file uploaded anywhere?
