About This Tool
The Dead Link Debugger is a deep structural editor that guarantees link interaction quality in published files.
Broken urls (404/500) inside manuals, whitepapers, or guides reduce branding authority. This tool lets you manage the hyperlinks database seamlessly.
It parses the low-level /Link dictionaries on each page, Probes them, and displays link status in an interactive grid (red for dead links, orange for redirects). Simply type the updated redirect URL, and the tool writes the new target directly back into the PDF binary stream.

Frequently Asked Questions
Why isn't link reachability fully checked online?
Web browsers enforce strict CORS policies that block direct multi-origin link checking. Our tool lists the links clearly and lets you hot-fix them manually.
Will this modify the visual text representation on the page?
No. It only alters the underlying `/URI` navigation action. The visual link text remains unchanged.
Does it support modifying internal page bookmarks?
This tool handles external `/URI` hyperlinks. For internal layout navigation, use our interactive TOC tool.
