Is there a software to add bookmarks into a PDF document automatically? A PDF that has a normal structure with some headings, etc.
I know that I can add bookmarks manually with softwares such as Adobe Acrobat, but I'm looking for a thing that I tell it which paragraphs are headings (or maybe knows itself) and then automatically add bookmarks into it.
I don't mean how to create a bookmarked PDF from a Word document, for example. I just have a book in PDF format and I would like to add bookmarks to it for ease of my personal use.
