關於此工具
Dead Link Debugger inspects every hyperlink in a PDF, flags the ones that no longer resolve, and reports — or replaces — the broken targets. It is a link hygiene tool for documents that are about to be published or distributed. Each URL is checked and marked as live, redirecting, or dead.
Product manuals, annual reports, and ebooks accumulate stale URLs fast. Before a client review or public launch, this tool verifies each link, shows you the status of every URL, and can swap failed links to corrected targets. The results are visualized in a link graph so you understand the structure at a glance.
Marketing teams recheck campaign PDFs whose tracking links change, legal teams verify cited sources in white papers, and publishers run the check before every new edition ships. Redirects can be flagged rather than silently followed, so you notice when a destination changed meaning. All link checking happens from your browser session, and the PDF itself is processed locally — nothing is uploaded. Free, no account, and a genuine quality gate for link-heavy documents.
Practical guidance before you use 失效鏈接修復
Best for real document workflows
Use 失效鏈接修復 when you need a quick browser-based result without creating an account or sending routine documents through an unnecessary upload workflow. Flyer broken links hotfix is a common example: Instantly correct wrong urls on published flyers without reopening original design editors.
Privacy and file handling
EasyPDFNex prioritizes local processing in your browser. That means supported PDF operations run on your device, not in a public cloud queue. For sensitive files, review the output before sharing it, close the browser tab after downloading, and avoid processing documents you are not authorized to edit.
Quality checks after processing
After you save redirect updates, open the result and check page order, text readability, signatures, links, and form fields. If the source file is scanned, encrypted, very large, or damaged, try a related workflow such as repair pdf, table of contents, edit metadata before repeating the task.
Start with a clean source file whenever possible. For 失效鏈接修復, the first step is usually "Provide target document": Upload the PDF manual or catalog containing links to debug. This simple preparation step prevents most failed exports, missing pages, and formatting surprises.

常見問題
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.
