How to Fix Broken Mailto Links in PDFs Exported from Word
Question details
The user needs to resolve an issue where exporting a Microsoft Word document to a PDF creates malformed or hidden mailto links out of plain text.

- Product
- Microsoft Word and PDF Readers
- Device & OS
- not provided
- Scenario
- Exporting a Word document containing specific text patterns, like phone numbers with parentheses, to a PDF format.
- Observed behavior
- The exported PDF contains unwanted, hidden, or broken mailto links because the PDF reader or export engine misinterprets certain punctuation and text patterns as URLs.
Ensure you have access to the original Microsoft Word document, as the most effective way to resolve this issue is by adjusting the text formatting before exporting.
Reformat Text in the Original Word Document
Modify the phone numbers or text formatting in Microsoft Word to prevent PDF engines from misinterpreting them as mailto links.
PDF readers often use automatic URL detection that gets confused by certain punctuation marks, especially parentheses near numbers. Changing the format of the text stops this auto-detection.
Launch Microsoft Word and open the document that is causing the hyperlink issues during export.
Find the text strings or phone numbers that are turning into mailto links. Look for numbers enclosed in parentheses, such as (800) 555-0123.
Delete the parentheses and reformat the number using hyphens or spaces instead, for example, 800-555-0123.
Go to File > Save As or File > Export, choose the PDF format, and save the document again to verify the unwanted links are gone.

Turn off the preference in Acrobat that automatically creates clickable links from text.
Use the Save As PDF Workaround Method
Use Word's 'Save As' feature to expose and remove the hidden mailto syntax embedded by the export engine.

Frequently Asked Questions
Why do phone numbers turn into mailto links in exported PDFs?
This happens because PDF rendering engines and export tools use pattern recognition to automatically create hyperlinks. Punctuation like parentheses around area codes can confuse the engine, causing it to misinterpret the number as an email address format, resulting in a mailto link.
Can I remove broken links from a PDF after it has been exported?
Yes. While you cannot do this in a standard PDF reader, you can use a PDF editing tool like WPS PDF Editor or Adobe Acrobat Pro to manually select and delete the hyperlink boxes from the exported document.
How do I stop Word from creating hyperlinks automatically?
In Microsoft Word, you can disable automatic hyperlinks by going to File > Options > Proofing. Click on 'AutoCorrect Options', navigate to the 'AutoFormat As You Type' tab, and uncheck the box for 'Internet and network paths with hyperlinks'.
