- Product
- Operating System File Manager
- Device & OS
- Windows / macOS
- Scenario
- Attempting to view a PDF file by double-clicking it after recently converting a PDF to a Word document.
- Observed behavior
- The PDF file opens in Microsoft Word instead of a dedicated PDF application.
Ensure you have a dedicated PDF reader or editor, such as WPS Office or Adobe Acrobat, installed on your computer before attempting to change the default file associations.
Reset Default PDF Application in Windows
Use the Windows context menu to permanently assign a PDF reader as the default application for all .pdf files.
This method updates the Windows registry file associations so that the operating system always knows which program to use when you double-click a PDF file.
Right-click on any PDF file saved on your Windows desktop or within File Explorer.
Hover over the 'Open with' option in the drop-down menu, then click on 'Choose another app'.
Select your preferred PDF viewer (such as WPS Office or Adobe Acrobat) from the list of available applications.
Check the box that says 'Always use this app to open .pdf files' (or 'Always' on Windows 11), then click 'OK' to save your changes.
Change Default PDF Viewer on macOS
Modify the 'Get Info' settings on a Mac to ensure all PDF documents open with your desired PDF application instead of a word processor.
Use WPS Office as Your Default PDF Reader
WPS Office features a powerful, built-in PDF toolkit. By setting it as your default application, you can view, edit, annotate, and convert PDFs seamlessly without relying on multiple programs.
- 1. Download and Install: Get WPS Office for free from the official website and complete the quick installation process.
- 2. Open File Association Settings: Launch WPS Office, click on the Global Settings icon, and navigate to the 'Configuration Tools' or 'File Association' menu.
- 3. Set as Default: Check the box next to PDF files to assign WPS Office as your default PDF reader and editor.
- 4. Open Your PDFs: Double-click any PDF document on your computer to instantly open it within the WPS Office PDF viewer.
Frequently Asked Questions
Why did my PDF files suddenly start opening in Word?
This commonly happens when you use a 'Convert PDF to Word' tool or install a new word processor. The operating system's default file association for the .pdf extension gets accidentally overwritten, causing the system to route those files to Microsoft Word.
Will changing the default application alter the contents of my PDF?
No. Changing the default file association only tells your operating system which program to use to open the file. It does not modify the file format, text, formatting, or any underlying data within the PDF itself.
What if my preferred PDF reader doesn't show up in the 'Open with' list?
If your application is missing, click 'More apps' or 'Look for another app on this PC' at the bottom of the 'Open with' menu. You can then browse your computer's 'Program Files' or 'Applications' folder to manually locate and select the executable file for your PDF reader.
