How to Fix Acrobat Reader Changing Picture File Associations
Question details
The user's image files are incorrectly opening with Adobe Acrobat Reader instead of their default photo viewer.

- Product
- Adobe Acrobat Reader
- Device & OS
- Windows and macOS
- Scenario
- Opening standard image files like JPEG or PNG after a system or application update.
- Observed behavior
- Images fail to open or display properly because the operating system has incorrectly associated picture formats with the PDF reader.
Ensure you know which application you prefer to use for viewing pictures (such as Windows Photos or macOS Preview) before changing your default system settings.
Reassign the Default Image Viewer Using the Context Menu
The quickest way to fix this issue is by using the 'Open with' command to permanently select your preferred photo application.
This method works on a per-file-type basis. You may need to repeat these steps for different image formats (e.g., once for .jpg and once for .png).
Locate any picture file (like a .jpg or .png) on your computer that is showing the Acrobat icon, and right-click on it to open the context menu.
Hover your mouse over 'Open with'. On Windows, choose 'Choose another app'. On a Mac, hold the Option key to change the menu option to 'Always Open With'.
Select your preferred photo viewer from the list (such as 'Photos' on Windows or 'Preview' on Mac). Make sure to check the box that says 'Always use this app to open files' (Windows), then click OK.

Modify Default Apps in Windows System Settings
If multiple image formats were changed simultaneously, you can restore them all at once through the Windows Settings menu.
Manage Documents and PDFs Effortlessly with WPS Office
Avoid file association conflicts by using an all-in-one suite. WPS Office includes a fast, reliable PDF reader and fully supports inserting and viewing images within your documents seamlessly.
- 1. Download and Install: Get the free WPS Office installer from the official website and run it on your Windows or Mac device.
- 2. Set as Default PDF Viewer: During or after installation, choose to set WPS PDF as your default reader. This safely handles your PDFs while leaving your image formats completely untouched.
- 3. Open and Manage Files: Double-click any PDF to open it in WPS Office instantly, knowing your pictures remain safely associated with your standard photo viewer.

Frequently Asked Questions
Why did Acrobat Reader take over my picture files?
This usually happens after a software update or if 'Always use this app' was accidentally selected when an image was opened in Acrobat. The operating system mistakenly registers the PDF reader as the default handler for standard image extensions.
Can Adobe Acrobat Reader open JPEG or PNG files directly?
While Acrobat can convert some image files into PDFs, it is not designed to be a standard photo viewer. Attempting to open raw images directly often results in an error message or an unexpected PDF conversion prompt.
How do I fix this file association issue on a Mac?
On macOS, right-click the image file, hold down the Option key to change the 'Open With' menu to 'Always Open With', select the 'Preview' app (or your preferred viewer), and click it to permanently restore the correct association.
