When the PDF Bookmark Tool seems to misbehave, the cause is usually one of two things: something stopped the tool from running, or it ran but the result is not usable. This guide starts with the fastest checks, then walks through the common problems and exact fixes.
Quick Checks First
- Refresh the page - a stalled session is the most common cause of nothing happening.
- Confirm the input is not empty and actually contains what you meant to submit.
- Try the smallest possible input; if that works, the issue is size, not the tool.
- Turn off browser extensions that block scripts, then reload and test again.
- Update or switch browsers if the problem repeats across sessions.
Common Problems and How to Fix Them
A bookmark opens the wrong page
Renumber the target - bookmarks store fixed page positions that shift after page changes.
The outline is too long
Nest sub-sections under chapters - two levels beat a flat list of fifty entries.
Bookmarks disappeared after merging
Merges carry bookmarks per source - rebuild the outline once over the combined file.
Names are unhelpful
Use the actual section titles from the document - navigation should mirror the content.
The sidebar shows nothing
Confirm the reader displays the bookmarks panel - the data exists in the file.
I need a printed table of contents
Bookmarks are digital - generate a printed TOC from the outline in your authoring tool.
When It Works but the Output Is Poor
If the tool runs fine but the result misses, the problem is almost always the brief, not the software:
- Pointing bookmarks at wrong pages after edits
- Flat outlines that duplicate the page count
- Forgetting bookmarks on merged documents
- Using vague names nobody can scan
How to Stop It Happening Next Time
- Keep a saved prompt template for every task you repeat.
- Change one setting per generation so causes stay obvious.
- Run a two-minute sanity test with known input after any update.
- Note every failure and its fix; a short troubleshooting log pays for itself.
Still Stuck?
Reproduce the problem with the smallest possible input and note the exact steps that triggered it. A one-line description of what you did, what you expected and what happened is enough to get a precise answer from support or a colleague.
