Problem: I have some images that don’t open in Photoshop CS. I get an error, ‘Could not complete your request because an unknown or invalid JPEG marker type is found.’ Although I can see their preview in my browser. How can I get around to access the pictures in PS?

How
to fix Photoshop JPG error ‘Unknown or Invalid JPEG Marker Type is Found’
Since the error is usually related to a wrong file format and extension, the troubleshooting involves correcting the extension, changing or renaming the image file. The invalid JPEG marker issue can also occur due to faulty hardware. So troubleshooting your PC hardware may also be one of the ways out.
Methods to fix ‘Unknown or Invalid JPEG marker’ error
- Change the image file extension
- Rename the image file
- Convert the image to a different format
- Open the file in another photo app
- Run hardware troubleshooting
Method
1: Change the image file extension
When you save an image file, the extension is added automatically. However, if you add the extension manually, then either it may have two extensions like filename.pdf.jpg or you might enter the wrong extension. To access a photo, the file extension should match the actual image file type.
So, view the file extension and make the
required change. Remove the last extension that you added, if you
see two extensions. Ensure the JPEG file has correct .JPEG or .JPG extension.
How can you view the file extension of your image?
File extensions are hidden by default on your computer. You can change the settings to view them.
Steps for Windows 10 users
- Go to Control Panel > File Explorer Options
- In the File Explorer window click on View tab
- Uncheck box to Hide extensions for known file types
- Click OK
Steps for Mac users
- Go to Finder > Finder Preferences >
Advanced
- Select Show all filename extensions
Method 2: Rename the image file
Renaming the image file along with its extension can often fix errors. You can always roll back to the original file name later anytime.
Steps to rename the photo
- Right-click on the JPEG photo
- Select Rename
- Change name and enter extension to JPEG or JPG
Now try to open this image in Photoshop. The invalid JPEG marker type error
should not appear.
If correcting the extension and renaming didn’t help, change the image format. Converting to a different file format like BMP or TIFF often fixes unknown JPEG marker errors. You can use online image converter tools or your Windows or Mac computer’s built-in options.
Steps to convert image file format in Windows Paint
- Open Paint
- Go to File >Open and select the image
- Go to Files. Click Save as

facing ‘invalid

in the photo app on your computer. You may use Photos on Windows or Preview on

the image in Photoshop to see if the invalid JPEG
marker issue is fixed or not.

work, check if your computer hardware is working fine or not. Issues
with your USB, cable, external hard drive, etc., can cause ‘Invalid JPEG marker
type’ error.
