Ever since the invention of the camera we have been clicking pictures and saving them to devices such as computers and mobile phones. We can view them, edit them and send them from one source
to another whenever we want to. These images are stored in the JPEG file format.
JPEG is a popular image format that we have been continuously using in our computers and smartphones for a longer period. Although we do not pay more attention to the format of the images as the images seem quite similar irrespective of the format. But, JPEG is the most prevalent image format due to its flawless display. This file format is supported by different devices and softwares over the period of time. Most of the image viewing applications depend on this format.
However, it isn’t that easy to save the pictures and the images over time and keep them protected from unauthorised sources. These images may be attacked by trojans and malwares and their quality might be compromised over the time. There are many reasons that may corrupt a JPEG file and you need to use a suitable repair method based on the level of corruption. The common causes of corruption have been provided in the following way:
- Shutdown of the system abruptly
- Disturbance in the system during transfer of images from one system to another.’
- Sharing the files through a wrong method
- Header related corruption in the JPEG images
- Inherent quality of the image is derogated
Here are some types of corruption that should be removed as soon as possible whenever you face them while trying to opening the image.
- Header Corruption
The header corruption in the image stops it from loading in the image viewer. If you are trying to open the image and it shows only the thumbnail of the JPEG format, then you should understand that the header part of the image is corrupt.
- Corruption in image data
A corruption in image data makes it more distorted, blurry, white-screen, or completely inoperable. Sometimes, the viewer tool shows the error of being unable to open the image.
- Malware attack
Malware can easily corrupt the JPEG files by altering their structure or data. That is why it can easily distort the image.
- Corrupt hard-drive sector
Hard drives always store the data in a specific format. If a hard-drive sector is corrupt, then the image will be corrupt also.
- Abrupt system shutdown
While you were using the image, if the system shuts down abruptly, then there are maximum chances that the image will also lose some data and have corruption.
