How Do I Fix an SOS Marker Error for Images

While JPG is a universally acceptable extension for images, it isn't the most secure one for sure. For instance, while working on JPG files, you might encounter all kinds of issues related to its header, marker, or any other meta component. Even though it might seem like a complicated situation to be in, you can try to fix an SOS marker error with images. Here, I will let you know why the SOS marker error is caused and what measures you can take to fix it.

Part 1: Things to Know about the SOS Marker Error

Before I discuss different ways to fix an SOS marker error with JPG images, let's cover some basics. Ideally, just like any other data file, JPG pictures also have a dedicated header that contains all kinds of crucial details about them.

A standard JPG header looks like this that has a dedicated SOS (Start of Scan) segment. Ideally, SOS and SOF (Start of Frame) are the two most vital parts of the header as they contain complex information about the image and would let any application know how it should be processed.

Now, if the SOS marker has been corrupted, damaged, or is missing, then it can lead to all kinds of issues with the file. In most cases, we encounter SOS marker issues with JPG files due to the following reasons:

  • Corruption of file while editing or transferring.

  • The header of the JPG file could be manipulated.

  • A forceful change in the file extension of the JPG photo.

  • If you are trying to process the file with any incompatible application.

  • At times, image editors like Photoshop can also alter its header, leading to SOS marker errors.

  • Any other issue related to the file’s mishandling or corruption.

Part 2: How to Fix an SOS Marker Error for your Images?

It has been observed that Adobe Photoshop users mostly encounter an SOS marker error with JPG files while exporting a project. Though, the SOS marker problem can take place due to any other reason and can be resolved in the following way:

Solution 1: Make Sure the File's Extension is Correct

One of the major reasons for getting an SOS marker issue is related to the file's incorrect extension. For instance, let's say that your image was of TIFF format, and you have forcefully converted it to a JPG format. In this case, the SOS part of the header would be compromised, leading to these unwanted issues.

Therefore, you can simply avoid performing a forceful conversion of your images to fix an SOS marker issue. You can also right-click the image and go to its properties tab to check all the crucial details of the file. From here, you can also check that the file extension for the image is correct or not.

Solution 2: Avoid Having More than One Extension for your Images

Apart from a forceful conversion of images to incompatible formats, having multiple extensions is another reason for SOS marker issues. Let's say there was an image of PNG format and you simply renamed it with a JPG extension. This would now lead to two extensions for the image that might corrupt its header.

You can simply check the overall extension of the file for which you are facing these issues. If you suspect that the image has multiple extensions, then you can manually rename it and remove its wrong extension type.

Solution 3: Load the Image with MS Paint

Yes - as surprising as it might sound, you can fix an SOS marker issue by simply opening the image with MS Paint. This is because MS Paint is a lightweight application that supports almost every image format.

Therefore, if you are not able to load an image on Adobe Photoshop, Photo Manager, or any other app, then you can try MS Paint. To do this, just launch MS Paint and go to its File > Open feature to browse and load the image that you can't seem to load.

Alternatively, you can also select any image in the Explorer, right-click, and go to the “Edit” feature to directly open it on MS Paint.

Solution 4: Save the Corrupt Image to PNG or JPG Format

Furthermore, you can also consider exporting your images to any other compatible format to fix an SOS marker issue. In most cases, this issue can be resolved by saving your pictures to compatible formats like PNG or JPG.

For this, you can first load the image you want to convert on MS Paint. Afterward, just go to its File > Save as option, and choose to export the image as a JPEG or PNG file. You can later save the converted image to any location of your choice on your system.

Solution 5: Perform Hardware Troubleshooting on your PC

This might sound surprising, but the SOS marker error is often occurred due to a hardware-related issue on systems. For instance, if any hardware component is damaged or is not working properly, then it can lead to these SOS marker problems.

Therefore, to fix an SOS marker error with your files, you can consider running a thorough diagnosis of its hardware. Just go to the Start menu and click on the gear icon to visit Windows Settings. Now, browse to its Update & Security > Troubleshoot Settings and run a troubleshooter for its Hardware and Devices section.
