Check Links in PDF Files Before You Publish

To check links in PDF files properly, you need to test more than visible blue URLs. A PDF can contain external web links, internal destinations, table-of-contents jumps, and linked annotations that stay hidden until someone clicks them.

What PDF Link Checks Should Include

• External URLs: support pages, product pages, policies, partner sites, and linked downloads.
• Internal destinations: page jumps, appendix links, table of contents items, and named destinations.
• Status details: 404, 410, redirects, timeouts, 403 blocks, and server errors.
• Editable targets: links that can be safely replaced without rebuilding the whole PDF.

When to Check a PDF

Check PDFs before launch, after a site migration, when support URLs change, and whenever a brochure, manual, or form has been online long enough for external references to decay. High-traffic PDFs deserve the same link QA as high-traffic landing pages.

Step-by-Step Workflow

1. Upload the PDF or paste a public PDF URL.
2. Separate external URL failures from internal destination issues.
3. Prioritize broken links that affect forms, support paths, pricing, or compliance pages.
4. Patch supported external PDF links when only the URL target changed.
5. Download the updated PDF and scan it again before publishing.

Use the PDF broken link checker to review a document, or open the PDF link fixing workflow when supported external URLs need replacement.
