Are you finding yourself in a frustrating loop where your PDFs consistently open in Google Chrome, even when you've set your preferred application to something else? You're not alone, and the solution might be simpler than you think. Let's dive into why this happens and how you can resolve this issue.

PDFs, or Portable Document Format files, are designed to display documents in a way that's independent of the application, hardware, or operating system used to create them. However, sometimes, your default PDF viewer might not be the one opening your PDFs, leading to unexpected behavior.

Understanding Default Applications
Your operating system uses default applications to open specific file types. When you click on a file, the system checks which application is set as the default for that file type and opens it with that application.

In the case of PDFs, if Chrome is opening your PDFs instead of your preferred application, it's likely because Chrome has been set as the default PDF viewer on your system.
Why Chrome Opens PDFs

Chrome, like many web browsers, has a built-in PDF viewer. This viewer is designed to be lightweight, fast, and capable of displaying most PDFs without requiring additional software. However, it might not offer the same level of functionality as dedicated PDF viewers like Adobe Acrobat or Foxit Reader.
If you've been using Chrome to view PDFs, it's possible that the browser has been set as the default PDF viewer, leading to the issue you're experiencing.
How to Change Default PDF Viewer

To stop Chrome from opening your PDFs, you need to change the default PDF viewer on your system. The process varies slightly depending on your operating system:
On Windows: Right-click on a PDF file, select "Open with" > "Choose another app", then select your preferred PDF viewer and check the box for "Always use this app to open .pdf files".
On macOS: Right-click on a PDF file, select "Get Info", then under "Open with", select your preferred PDF viewer and click "Change All...".

Additional Troubleshooting Steps
If changing the default PDF viewer doesn't solve the issue, there are a few other things you can try:

Check your Chrome settings: Ensure that Chrome isn't set as the default PDF viewer within the browser itself. Go to "Settings" > "Download" and make sure "Open PDF files in the default PDF viewer" is not checked.
Check your PDF viewer settings: Sometimes, your preferred PDF viewer might be set to open PDFs in a web browser. Check the settings of your preferred viewer to ensure it's not set to open PDFs in Chrome.
Remember, the key to resolving this issue is to ensure that your operating system is using the correct default application for opening PDF files. With a little troubleshooting, you should be able to stop Chrome from opening your PDFs and use your preferred viewer instead.
