How to Fix JPEG Files Appearing as PDFs After Installing Acrobat
Question details
JPEG image files display PDF icons and automatically open in Adobe Acrobat instead of a standard image viewer following the installation of Acrobat DC.
- Product
- Windows / Adobe Acrobat DC
- Device & OS
- Windows
- Scenario
- Attempting to view or open existing JPEG images after recently installing Adobe Acrobat DC on a Windows computer.
- Observed behavior
- The image files have visually changed into PDF documents on the desktop and in folders, and they trigger Adobe Acrobat to open instead of an image viewer. The underlying image files themselves have not been converted, but their file association has been modified.
Verify that your files still have the .jpg or .jpeg extension. This issue is typically caused by a change in your Windows default app settings rather than an actual conversion of your image files, so do not delete or attempt to manually rename the file extensions.
Restore Default Image Viewer via 'Open with' Settings
The quickest and most direct way to fix file association issues in Windows is to assign a new default program directly from the affected file.
When you install Adobe Acrobat DC, the software may automatically set itself as the default application for various file formats, including images. This changes the file icon and the default opening behavior, but your original image files remain completely intact. You simply need to re-link them to an image viewer.
Find any of the affected JPEG files on your desktop or within File Explorer, and right-click on it to open the context menu.
Hover your mouse over the 'Open with' option. Do not double-click the file to open it.
From the expanded menu, click on 'Choose another app' or 'Choose default program' at the bottom of the list.
Select your preferred photo viewer application (such as Windows Photos). Ensure that the checkbox for 'Always use this app to open .jpg files' is checked, then click 'OK'.
Update Default Apps via Windows Settings
Use the main Windows Settings menu to comprehensively manage and correct default applications by file type.

Frequently Asked Questions
Did Adobe Acrobat convert my JPEG images into PDF files?
No, Adobe Acrobat DC did not convert or alter your actual files. It simply changed the default application associated with opening .jpg and .jpeg files, causing Windows to display them with PDF icons.
How can I prevent software from changing my file defaults in the future?
During software installations or major updates, pay close attention to the setup prompts. Uncheck any optional boxes that offer to make the new software the default viewer for all supported file types.
Why do my files show a blank or generic icon after changing the default app back?
Sometimes the Windows icon cache fails to update immediately after changing file associations. You can easily fix this by restarting your computer or by restarting Windows Explorer from the Task Manager.
Can I change the default app for multiple image formats at once?
Yes. Navigate to Windows Settings > Apps > Default apps > Photo viewer, and select your preferred image application. This will automatically associate most standard image formats (like PNG, BMP, and JPEG) with that application in one click.
