How to Stop Chrome from Becoming the Default PDF Viewer
Question details
Users need a way to prevent Google Chrome from automatically overriding system settings and becoming the default application for opening PDF files.

- Product
- Google Chrome / Windows 10
- Device & OS
- Windows 10
- Scenario
- Opening downloaded or local PDF files on a Windows computer.
- Observed behavior
- Google Chrome repeatedly hijacks the default PDF file association, forcing PDF documents to open in the browser instead of a dedicated PDF reader.
Ensure you have administrator privileges on your Windows computer, as modifying system-wide default application settings or adjusting domain group policies requires admin access.
Set Your Preferred PDF App via Windows Settings
Use the Windows 10 settings menu to firmly assign your preferred PDF reader as the default program for all .pdf files.
Press the Windows key + I on your keyboard to open the Windows Settings menu, then click on the 'Apps' category.
Select 'Default apps' from the left-hand sidebar menu. Scroll down to the bottom of the page and click on the 'Choose default apps by file type' link.
Scroll down the alphabetical list of file extensions until you find '.pdf'. Click on the current default app next to it (likely Google Chrome) and select your preferred PDF reader from the pop-up list.

Adjust Google Chrome's PDF Settings
Configure Google Chrome to download PDFs instead of automatically opening them within the browser.
Check Domain Group Policy (For Work Computers)
If you are on a company network, IT policies might be automatically resetting your default apps upon every login.
Use WPS Office as Your Reliable Default PDF Reader
WPS Office offers a dedicated, lightweight, and feature-rich PDF reader and editor that flawlessly integrates with Windows, offering stable file associations without constant browser hijacking.
- 1. Download and Install WPS Office: Download the free version of WPS Office from the official website and complete the installation process.
- 2. Set WPS as the Default Reader: During the installation prompts, or by navigating to Windows Settings > Apps > Default apps, set WPS Office as the default application for .pdf files.

Frequently Asked Questions
Why does Chrome keep taking over my PDF files after a Windows update?
Major Windows or browser updates can sometimes reset file associations to system defaults or browsers like Microsoft Edge and Google Chrome. You can easily reassign your preferred PDF reader in the Windows 'Default apps' settings.
Can I still view PDFs in Chrome occasionally if I change the default app?
Yes. Even if a dedicated app like WPS Office is your default system PDF reader, you can still right-click a local PDF file and select 'Open with' > 'Google Chrome', or simply drag and drop the PDF file directly into an open Chrome window.
Does this issue happen on Windows 11 as well?
Yes, Windows 11 users may experience similar default app resets. To fix it in Windows 11, go to Settings > Apps > Default apps, search for '.pdf' in the search bar, and change the assigned application to your preferred PDF reader.
What if I don't have Adobe Acrobat installed?
If you do not have Adobe Acrobat, you can use any other dedicated PDF reader like WPS Office. Simply install the software and select it as your default PDF program in the Windows settings.
