When you attempt to open a JPEG file on your computer, your computer may display a message saying “Image cannot be opened or viewed”. This happens because you haven’t installed appropriate software on your computer to open JPEG file format. So you can either install a photo viewer software or change the default image viewer to the “Windows photo viewer”.

Conclusion: Let's figure out what causes JPEG corruption?

Various reasons might lead you to corrupted images. I have outlined some most common reasons below.

1. Broken or Corrupted Header of JPEG File

Every JPEG file contains two parts: the header and actual binary data. So, if any chance header file is corrupted, then you won’t be able to view your images as you normally do. You have to take the help of the Hex editor to fix the corruption of the JPEG file.

2. Corruption in JPEG Image Data, Like Half Grey Image

Data corruption is a fairly common problem that prevents JPEG files to load. Even if an image opens, it may show a half grey or black screen instead of the actual image. Mainly JPEG image data got corrupted because of the abrupt file transfer process or your computer hard drive may contain bad sectors. You can click here to get more information - Fix half or full gray or black photos easily.

3. Viruses or Malware Attack

Viruses and malware are the evil of computers. Any virus or malware attack can corrupt the binary data of the image and will lead to image corruption.

4. The Storage Device Has Bad Sectors, or the File System Has Corrupted

Storage devices such as Hard Drive can cause data corruption through the events of bad sectors. Bad sectors are the tiny cluster of the storage space that appears to be working properly. The sector will not respond to the computer’s read and write requests. In the case of bad sectors, users will not be able to access images.
