Summary: Photoshop is the most versatile software used by the designers but working on it can be difficult sometimes. There can be multiple errors such as “An Unknown or Invalid JPEG Marker Type is Found” that we face in Photoshop. Not being able to edit or enhance your valuable photos with special effects in Photoshop is not only frustrating but can also affect the quality of your work. So here, we bring a few effective solutions to fix the unknown or invalid JPEG marker error.
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?
Solution: You have not saved the JPEG image file in a proper format. For instance, if you save a JPEG file in a TIFF format, it will preview as a thumbnail but will show invalid JPEG marker error when you try to open in PS.

In spite of the images being viewable on computer drive or browser, Photoshop users commonly face the error – ‘unknown or invalid JPEG marker type is found’ when they try to open a picture in it.

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’ errorWhen 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 a 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
Steps for Mac users
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
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 error. 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 the image facing ‘invalid jpeg marker type is found’ error in the photo app on your computer. You may use Photos on Windows or Preview on Mac.
Next, save the photo again as a JPEG image within the app. Now try to open the image in Photoshop to see if the invalid JPEG marker issue is fixed or not.
If the above methods don’t 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.
Run a hardware troubleshooting. It will automatically fix the hardware issue, if any.
Steps to PC hardware troubleshooting
Now, open the JPEG image in Photoshop and check if the JPEG error is resolved or not.
If none of the above methods could fix the JPEG marker error, chances are your image has turned corrupt. Use a Professional Jpeg repair tool like Stellar Repair for Photo to fix the corruption in such JPEG files.
