Solution 1Recommended

Adjust Microsoft Word Macro Security Settings

Modify Word's Trust Center settings to allow Adobe Acrobat macros and add-ins to run during the PDF conversion process.

Adobe Acrobat uses a Word add-in called PDFMaker to process the conversion. This add-in requires permission to run background macros. If Word's security is set too high, it blocks Acrobat from completing the task.

1
Open Word Options

Launch Microsoft Word, click on the "File" tab in the top-left corner, and select "Options" at the bottom of the menu.

2
Access the Trust Center

In the Word Options dialog box, select "Trust Center" from the left pane, then click the "Trust Center Settings" button.

3
Modify Macro Settings

Select "Macro Settings" from the left sidebar. Choose "Disable all macros with notification" or temporarily select "Enable all macros" to allow the conversion. Also, check the box for "Trust access to the VBA project object model".

4
Restart Applications

Click "OK" to save your changes and close the dialog boxes. Completely close and restart both Microsoft Word and Adobe Acrobat, then attempt the PDF conversion again.

Adjust Microsoft Word Macro Security Settings
Security Warning: If you choose "Enable all macros", your computer may be vulnerable to potentially malicious code. It is highly recommended to revert this setting to a safer option after successfully converting your document.

Frequently Asked Questions

Why does Adobe Acrobat require macros to convert Word to PDF?

Adobe Acrobat uses a specialized add-in (Acrobat PDFMaker) integrated directly into Microsoft Word. This add-in utilizes macros to accurately transfer advanced formatting, bookmarks, and hyperlinks from the Word document to the resulting PDF. If Word blocks these macros, the conversion process halts.

Can I convert Word to PDF without changing my macro security settings?

Yes. Instead of using the Acrobat add-in, you can use Word's native "Save As" feature and choose "PDF" as the file format. Alternatively, you can use comprehensive office software like WPS Office, which handles PDF conversion natively without requiring external macro permissions.

What should I do if the macro security dialog doesn't appear in Word?

If the security dialog does not trigger automatically when Acrobat tries to convert the file, you must manually adjust the settings. Go to File > Options > Trust Center > Trust Center Settings > Macro Settings in Microsoft Word, adjust the permissions, and then restart the application.
