Vellum opens the table of contents of a PDF document and makes it editable: every bookmark can be renamed, pointed at another page, indented one level, moved or deleted. A document with no outline starts from an empty list, to which you add your own entries until you have a clickable plan — useful on a report, a dissertation or a contract running to dozens of pages. The saved file keeps its text, images and fonts untouched: only the bookmark tree is rewritten. Reading and writing both happen on your own device, and the document is never sent to a server.
