How to Repair Corrupt JPEG Files on a Computer

JPEG files, the ubiquitous method of storing digital images, can sometimes be corrupted for a variety of reasons, including software bugs, hardware errors or incomplete downloads If you encounter corrupted JPEG files a, it can be frustrating and even frustrating. However, there are many ways you can organize these files and reclaim your precious memories. This article will walk you through the steps to repair corrupted JPEG files on your computer.

Understanding JPEG corruption 

Before diving into recovery options, it’s important to understand what happens when a JPEG file gets corrupted. JPEG corruption can manifest itself in several ways:

• Incomplete image: Some parts of the image are missing or have been replaced by solid colors.
• Distorted image: The image may appear with artifacts, discoloration, or pixilation.
• Unreadable files: No image viewer or editor can open the file.

These problems usually occur because parts of the file data are missing or have changed. JPEG files consist of a series of blocks, each containing different information such as image resolution, color profile, and actual pixel data. Corruption can affect any of these aspects.

7 Methods to repair corrupted JPEG files

1. Use the Built-In Tools

Most operating systems have built-in tools that can sometimes handle special JPEG corruption.

Windows Image Viewer

Open the file: Right-click the corrupted JPEG file and choose “Open with” > “Photos” or “Windows Photo Viewer”.

Editing and saving: When the image opens, it can attempt to do some editing (e.g., cropping or rotation) and then save it. Sometimes this process can prevent minor corruption by rewriting the file.

Preview on macOS

Open File: Double-click to open a JPEG file in preview.

Export the file: Go to “File” > “Export” to save the image in another format (e.g., PNG or TIFF). After that, you can convert it back to JPEG if you need to.

2. Try using another image viewer or editor

Sometimes the problem is not with the file itself but with the software you use to open it. Image viewers and editors handle files differently and are more resistant to certain types of corruption.

IrfanView (Windows): IrfanView is a small image viewer that can sometimes open corrupted JPEG files that other viewers cannot. If IrfanView can open the file, you can save it as a new file.

GIMP (Windows, macOS, Linux): GIMP is a powerful, free graphics editor that should be able to open and edit files. Open the corrupted JPEG in GIMP and then export it as a new JPEG file.

Photoshop: Adobe Photoshop is an advanced tool that can often handle corrupted files better than a basic image viewer. Try opening the file in Photoshop and saving it in a different format.

3. Use the Command-Line Tools

For those comfortable with the command-line interface, tools such as jpeginfo and jpegtran can be used to edit JPEG files on Unix-like systems.

Japegtran: 

Install jpegtran: If you are on Linux, install jpegtran using your package manager (e.g., sudo apt-get install libjpeg-progs on Ubuntu).

Fix the file: Run the command jpegtran -copy none -optimize -perfect -outfile output.jpg corrupt.jpg and try to fix the file.

jpeginfo: .

Install jpeginfo: Install jpeginfo using your package manager (e.g., sudo apt-get install jpeginfo).

Check the file: Run jpeginfo -c corrupt.jpg to check for errors in the file. This tool can help you understand what is wrong with the file.

4. Use a Hex Editor (Advanced Users):

For those with technical expertise, a hex editor can be used to manually edit the file’s binary code. However, this method requires caution as incorrect modifications can further damage the file.

For those comfortable with low-level file editing, a hex editor to manually edit JPEG files may be a last resort. JPEG files begin with the hex code “FFD8” and end with “FFD9”. If these symbols are missing or incorrect, the file will not display properly.

Steps to use the Hex Editor:

• Open the file: Use a hex editor like HxD or Hex Fiend to open the corrupted JPEG file.
• Check header and footer: Make sure the file starts with “FFD8” and ends with “FFD9”.
• Edit and Save: If the title or footer is incorrect, correct it manually and save the file.

Note: This method is advanced and should be used with caution. Inappropriate changes can further corrupt the file.

5. Change the name of the File Extension

Sometimes incorrect file extensions can cause corruption. Sometimes renaming the file extension can expose the image.

Rename the File: Right-click the JPEG file and select “Rename”. Change the extension from “.jpg” or “.jpeg” to another image, such as “.png”.

Try to open the file: Try to open the file with the image viewer. Once it opens, you can use an image editor to save it back to JPEG.
