How to Tell if a JPEG is Corrupted?

Before you dive into the repair process, it’s essential to identify whether a JPEG file is truly corrupted. Here are some signs that your JPG file may be corrupted:

The file does not open: If you can't open the JPG file or you receive an error message such as “file format not supported,” it’s a strong indication of corruption.

Error messages: You might receive specific error messages like “The file is damaged and cannot be opened” or “JPEG file is corrupted,” indicating corruption.

Distorted images: Sometimes, a corrupted JPG might open but display a scrambled or distorted version of the original image. This could include random lines, odd color schemes, or a partially visible image.

Blank screens: If you double-click on the file and only a blank white screen appears, it’s likely that the file is corrupted.

Why Do JPEGs Get Corrupted?

There are many factors that contribute to JPEG corruption. Understanding these causes can help prevent future issues. Some of the most common reasons include:

Interrupted file transfers: If the JPEG file was transferred between devices and the process was interrupted, it could lead to corruption.

Bad sectors on a storage device: If the storage media (e.g., hard drive, SD card, USB drive) has bad sectors, the data, including JPEG files, might get corrupted.

Power outages or crashes: Abrupt shutdowns or crashes during the file saving process can cause incomplete data and corruption in JPEG images.

Virus or malware attacks: Malicious software can alter or delete data, potentially corrupting image files.

Software or hardware malfunctions: If an image is opened or edited with faulty software or hardware, the resulting file may become corrupted.

1. Right-click on the corrupted file and select Rename.

2. Change the file extension from .jpg to .jpeg or vice versa.
