How to Fix Broken PDF Hyperlinks Caused by Hyphens After PDF Printing
Question details
Users experience broken hyperlinks resulting in 404 errors when converting Word documents to PDF via the Adobe PDF printer, specifically due to hyphen encoding issues.

- Scenario
- Converting a Word document containing URLs with hyphens into a PDF document using a print-to-PDF function.
- Observed behavior
- Hyperlinks that work perfectly in the source document fail in the resulting PDF, leading to a 404 error because the standard hyphen is translated into a visually identical but structurally different Unicode hyphen.
Before attempting to fix the conversion issue, verify that the original hyperlinks in your Word document function correctly by clicking them, and identify exactly which URLs are generating 404 errors in the output PDF.
Replace Unicode Hyphens with Standard ASCII Hyphens
Manually replace visually identical special hyphens with standard keyboard hyphens to ensure the PDF printer correctly encodes the URL.
Word processors sometimes automatically convert standard hyphens into special Unicode characters like en-dashes or non-breaking hyphens. While these look identical, a PDF printer will encode them differently, causing the browser to misread the URL.
Open the original Word document containing the problematic hyperlinks.
Find the specific URLs that returned a 404 error when clicked from the converted PDF.
Delete the existing hyphen in the URL and manually type a standard ASCII hyphen using the minus key on your keyboard. Do not let auto-correct change it.
Save the document and print or export it to PDF again to verify the link now works properly.
Use Built-in PDF Export Tools Instead of 'Print to PDF'
Avoid using the 'Print to PDF' function, which only analyzes visual text, and instead use native export tools that retain true link metadata.
Retain Perfect Hyperlinks by Converting to PDF with WPS Office
WPS Office features a highly accurate built-in PDF converter that seamlessly preserves true hyperlinks from your Word documents, avoiding the encoding and hyphenation errors common with virtual PDF printers.
- 1. Open your document in WPS Writer: Launch WPS Office and open your Word document containing the hyperlinks.
- 2. Access the Export to PDF tool: Click on 'Menu' in the top-left corner and select 'Export to PDF' from the dropdown list.
- 3. Configure export settings: In the pop-up window, ensure the save path is correct. WPS automatically preserves hyperlinks without needing extra configuration.
- 4. Export and verify: Click the 'Export to PDF' button, open the resulting PDF, and click your links to confirm they work perfectly.
Frequently Asked Questions
Why does a hyperlink look correct in the PDF but lead to a 404 error?
During the print-to-PDF process, virtual printers sometimes convert standard hyphens into special Unicode characters (like an en-dash). While visually identical on the PDF page, your web browser reads it as a completely different character, resulting in a broken, unrecognized URL.
Does 'Print to PDF' retain original document links?
Not reliably. Most 'Print to PDF' tools, including the Adobe PDF printer, only analyze the visual text on the page to guess where links are. They do not transfer the true, embedded hyperlink metadata from the original document.
How do I know if my document uses a Unicode hyphen?
If your URL breaks at the hyphen when clicked, copy the URL directly from the PDF and paste it into a plain text editor like Notepad. If it uses a Unicode hyphen, you will often see the character change shape or appear differently than a standard minus-key hyphen.
Can I fix the broken link directly in the PDF?
Yes, if you use a premium PDF editor. You can select the broken link using the Link tool, open its properties, and manually edit the destination URL to replace the special hyphen with a standard keyboard hyphen.
