What Are PDF Bookmarks?
Bookmarks, also called the outline, are the clickable table of contents in the side panel of a PDF reader. Word, Google Docs and most publishing tools create them from headings.
Because each bookmark points to the page where a chapter starts, they are the natural place to cut a long PDF. When you split PDF by bookmarks, every file starts at a bookmark and is named after it, such as 03-payslips.pdf.
If a PDF has no bookmarks, the tool tells you, and you can add them with Add bookmarks to PDF.

Sections
Second-level bookmarks too.
Named files
