Repair Corrupt JPEG/JPG Image Files, Possible Free Methods

JPEG is the 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 lossless compression and its support to the majority of smartphones and professional cameras.

As the security features of the computers have grown better with each operating system, the threats to the computer’s data have also grown exponentially. There are multiple reasons for a corrupt JPEG image file and you need to use a suitable repair method based on the level of corruption. If you have some images that were opening easily earlier, but now not opening in any image viewer tool or they are showing any kind of error, then you should look for the possible cause of JPEG error and its solution.

Here are some types of corruption that should be removed as soon as possible whenever you face them while trying to open 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 that it is unable to open the image.
  • Malware attack
    If you are suspicious of a malware attack on the computer, then the images may be the most vulnerable files to be affected by it. Malware can easily corrupt the JPEG files by altering their structure or data.
  • Corrupt hard-drive sector
    A sector in the hard-drive is the specific part where it saves the information of the drives. If a hard-drive sector is corrupt, then the image will be corrupt also.
  • Abrupt system shutdown
    If the system got a power cut and the system was shut down abruptly and you were using the image, then there are maximum chances that the image will also lose some data and have corruption.
