Question details
The user experiences blank Microsoft Word pages opening repeatedly for each document when trying to merge multiple files into a single PDF on a specific computer.
- Product
- Microsoft Word / PDF Creator
- Device & OS
- not provided
- Scenario
- Creating a single PDF document by merging multiple files, including Word documents.
- Observed behavior
- Blank Microsoft Word 2016 pages automatically open for every Word document being merged, interrupting the PDF creation process, whereas other computers on the network work perfectly.
Ensure you have administrator privileges on the affected computer to modify default system applications, and verify that both your PDF creation software and Microsoft Word are updated to their latest versions.
Configure Default Applications for PDF Files
Set your operating system to open PDFs exclusively in a dedicated PDF reader rather than Microsoft Word to prevent application conflicts.
When file associations are misconfigured, your computer might attempt to use Microsoft Word as the default handler for PDF files. This causes Word to launch blank instances repeatedly during batch conversion or merging tasks.
Click the Start menu and select the gear icon to open Settings, then click on 'Apps'.
Select 'Default apps' from the left-hand menu, scroll down, and click the 'Choose default apps by file type' link.
Scroll through the list to find the '.pdf' extension. If Microsoft Word is listed next to it, click on it and change the default application to Adobe Acrobat, WPS Office, or your preferred PDF reader.
Close the settings menu, restart your PDF creation software, and attempt to combine your multiple files into a PDF again.
Repair Microsoft Office and PDF Creator Installations
A corrupted Office installation or a faulty PDF integration add-in can cause Word to behave erratically during file conversions.

Frequently Asked Questions
Why does Microsoft Word open when I try to convert multiple files to PDF?
This usually happens when your system's file associations are incorrectly configured, forcing the PDF creator to use Word's rendering engine in the foreground, or if your default PDF application is mistakenly set to Microsoft Word.
Can a faulty Acrobat add-in in Word cause blank pages during conversion?
Yes. If the Acrobat PDFMaker add-in is corrupted, outdated, or conflicting with other Office plugins, it can trigger Word to open blank pages repeatedly instead of silently converting the documents in the background.
How do I stop Microsoft Word from being my default PDF reader?
Navigate to your computer's 'Default apps' settings in the Windows Control Panel or Settings app. Search for 'Choose default apps by file type', locate the '.pdf' extension, and change the associated program from Microsoft Word to a dedicated PDF viewer.
Is there a way to merge PDFs without opening Microsoft Word at all?
Yes. By using a unified office suite like WPS Office with native PDF tools, or a standalone PDF editor, you can merge documents directly without relying on background processes that invoke Microsoft Word.
