Common questions
Does this change the visible PDF pages?
No. Bookmark writeback changes the PDF navigation outline, not the visible page content.
Where do the proposed bookmarks come from?
Pdf Clarity reuses existing outline entries when they are present and otherwise falls back to heading heuristics discovered in the current PDF.
