Bookmark candidates
A QUICK WALKTHROUGH
How to use this tool
- Extract or copy heading text using your PDF workflow.
- Paste one heading per line.
- Detect and review bookmark candidates.
Text candidates only
This tool accepts pasted extracted text. It does not open PDFs, inspect page locations, or write bookmarks back into a document.
Local and reviewable
Candidates are generated in the browser as JSON with title, level, and source line. Numbered headings determine nesting hints; review them before using another PDF workflow.
GOOD TO KNOW
Common questions
Does it read a PDF file?
No. Paste extracted heading text; no PDF file access is implemented.
Does it write bookmarks automatically?
No. It only returns candidates for review or use elsewhere.
How are levels inferred?
A heading beginning with numbering such as 2.1 gets a deeper level based on its dot segments; other lines are level 1.
