Kernel Photo Repair - Fix Broken or Corrupt JPEG File Headers

How to Fix Broken or Corrupt JPEG File Headers?

Due to unforeseen circumstances, multimedia files can get damaged or corrupted easily. If you try to open any damaged JPEG or JPG files, then you receive an error stating the probable cause. A JPEG image is comprised of two parts, i.e., the header and the actual binary image data. So, if the header is corrupted, then it is by far the easiest to repair, using a sample file and a Hex editor such as HxD. In short, it is possible to replace the corrupted header with a healthy header from another healthy image file. Repairing the image data, on the other hand, is a much more complicated and tedious task. Now, we are going to specifically discuss free methods for repairing JPEG Files. Caution should be taken with the image files as a little negligence can cost you a lot later. Following are the top reasons that are responsible for the JPEG/JPG file corruption:

  • JPEG/JPG header corruption.
  • Malicious attacks on the JPEG files.
  • Damaged/bad sectors on the storage media, where JPEG files are stored.
  • Improper system shutdown, causing multimedia file corruption.
Method #1 Repair Corrupt JPEG Headers Using Hex Editors

This is an easy way to repair a corrupt header. The only requirement is a healthy image file from the same device (and format) on which the affected image was captured. Using a Hex editor, you can easily replace the header of the affected file with the header from a healthy file.

Method #2 Repair Corrupt JPEG Headers When Healthy File Headers are Unavailable

In the previous method, we had access to a healthy header file. So, if you don’t have access to a healthy header filer then don’t panic as you can create one by following few easy steps as described below:

  1. Launch the Paint application from your PC.
  2. Scribble or draw anything in the black space.
  3. Next, go to File > Save As > JPEG picture.
  4. In the Save As dialog box, provide the location to save the newly created JPEG file.
  5. Enter the filename and click on the Save button.
  6. Next, proceed to import the newly created JPEG file and the affected file in the Hex editor.
  7. The Hex editor will attempt to repair the affected file.

The aforementioned steps might seem easy, but in practice, it is quite difficult to come by a good and reliable Hex editor. Image corruption issues are complicated and vary from case to case; hence every issue requires a different approach. Hex editors rarely live up to the user’s expectations; hence we require a professional photo recovery tool, which we are going to discuss in the next section.
