PDF Bookmark Viewer
Inspect the document outline already stored in a PDF, expand nested entries, and preview the page behind an internal bookmark.
A QUICK WALKTHROUGH
How to use this tool
- Choose one local PDF up to 20 MB and 500 pages.
- Load its existing outline and select a bookmark with an internal page destination.
- Expand nested entries and preview the destination page. The file is never uploaded or modified.
Read and navigate existing bookmarks
The viewer reads the PDF outline, preserves its nested order, and lets you preview pages with resolvable internal destinations. Entries without a supported internal page target remain visible but cannot be used for page navigation.
Local, read-only processing
The PDF is opened in this browser and is not uploaded or changed. Password-protected, damaged, or unsupported PDFs may not open. Documents are limited to 20 MB and 500 pages; page previews are bounded to 12 megapixels.
Not a bookmark editor or signature validator
This is a read-only outline viewer. It cannot add, rename, reorder, indent, or delete bookmarks, and it does not validate PDF signatures, certificates, or trust.
GOOD TO KNOW
Common questions
Can I edit or save bookmarks?
No. This tool only reads the existing outline and previews internal destinations; it never modifies the PDF.
Why can I see a bookmark but not open it?
Some entries have external links or destinations that this browser viewer cannot resolve safely. Such entries remain visible without opening the target.
Does it work with scanned PDFs?
It can read bookmarks in a scanned PDF, but it does not perform OCR. The page preview remains an image rendered by PDF.js.
Is my PDF uploaded?
No. The PDF and page previews stay in your browser.
