One of the prime reasons for “An unknown or invalid JPEG marker type is found” is an incorrect file extension. It generally happens when any user had tried to change the file extension manually previously. The user has either misspelled the extension or written two extensions together against the file, causing it unreadable in the Adobe Photoshop application for editing and other processing purposes. So, it is advised to modify the current file extension manually using this way.
If you know the original name of the file, you can anytime rename the current file, which name may be changed multiple times before using it in the Photoshop application. The renaming of the file is just simple. You can select the file and press the F2 key on the keyboard, now type the original file name.
Or right-click the concerned file to select the Rename option from the drop-down list and change the file name hen.
You can check if the extensions for known file types are not hidden as they can cause the error. In Windows 10 user, try these steps to check this option.
