What are the common instances of a corrupt or damaged JPEG file?

There are different ways by which a JPEG or JPG file can get damaged. Ideally, it would depend on the trigger and various other conditions. The following are some commonly faced problems with photos on Mac and Windows.

• Gray areas in an image In this, any damaged area on a picture is replaced by gray boxes. This happens when the pixel information for these areas become missing. It usually happens when the file is disturbed during processing.

• Damaged colors in an image It happens when the original color palette of a photo is damaged. A distortion, blur, or split image can be triggered by it.

• Wrong colors in an image Either the original colors would be changed into something else or would go missing entirely. A compatibility issue or mishandling by a third-party tool can cause it.

• Damaged picture header As you know, every JPEG file has a header (in hexadecimal). When the header is damaged or altered, it makes the file corrupt or inaccessible.
• Heavily damaged picture data A severe defect can happen on any JPEG file when its data gets damaged. A malware attack or unexpected shutdown mostly does this.

• Missing JPEG image header A file can be inaccessible or corrupt when the header becomes missing entirely.

• Other issues Besides that, plenty of other issues can also happen. Some of them are JPEG files can't be opened, invalid image error, unknown format, grainy pictures, split images, no preview available, and more.
