Stellar JPEG repair is now Stellar Repair for Photo I noticed Stellar renamed their photo repair tool from ‘Stellar Phoenix JPEG Repair’ to ‘Stellar Repair for Photo’. ‘Photo Repair’ suggests that rather than being limited to repairing JPEG, it also supports other digital photo formats. I visited their website and downloaded the new version. This… Read More »
Recovered photos are corrupt and won’t open after you tried to recover them using undelete, file recovery of photo recovery software? Here’s a few things to try.

There’s basically three things that can be wrong if a JPEG opens but is partially grey:
1. File is too small. Let’s an average JPEG shot with same camera and settings is 4 MB and the ones that are damaged are like 1 MB or 2 MB. Then probably half the data is simply missing. These files can not be repaired.
2. Normal file size. Either part of the file does not contain image data or file does contain image data but is interrupted by some invalid data.
If part of the file does not contain image data then this is sometimes easy to spot using a hex editor. All of a sudden ‘random’ binary data stops and changes to FF FF FF or 00 00 00 etc.. Repair: Impossible.
In case the data is however is there but it is interrupted repair is often possible. JPG-Repair tries to detect and will try to get rid of the invalid data, however this does not always work. Current version detects invalid JPEG markers, common damage due to bad sectors and some type of corruption I observed a few times with images shot with certain Samsung phones.
How to repair a corrupted JPEG photo may seem a simple question but the answer isn’t. Many people seem to expect to run some JPEG Repair software and that fixes it. And that’s what many of my competitors promise. If only it were that simple. Now, let’s take this one step at the time to… Read More »

Commonly Canon RAW photos embed one or more JPEGs: a low resolution thumbnail, a medium resolution preview, and in many cases… Read More »
Windows Photo Viewer: File appears to be damaged, corrupted or is too large The first thing you need to check is if other photo viewers can actually open the file. For example try Windows Photos or a third party photo viewer. If those fail to open the photo as well, the file may be corrupt. If… Read More »
Can corrupt Canon CR2 RAW photos be repaired? As expected there is no yes/no answer possible top this question. If you’re unable to open the file at all then perhaps, but definitive answer is only possible after closer examination of the file. Windows Photos will simply state: “It appears we don’t support this file format”… Read More »
Recover Canon CR2 RAW photos. Canon CR2 raw files contain unprocessed raw sensor data. Depending on the camera’s resolution they tend to be quite large and due to typical usage patterns (preview photo > dismiss/delete file > shoot new file etc.) the files become easily fragmented. Shoot video too? Then fragmentation is very likely to… Read More »
Comparison between various tools for photo recovery The case of the corrupt JPEG files Sometimes it turns out photos can not be repaired after recovery.

There are many tools available to recover lost or deleted digital photos from memory cards. Most of them are unable to recover non contiguous or fragmented files. As a result fragmented files recovered by such tools will be corrupt. In such cases JPEG Recovery LAB can help you recover fragmented files. However, recovered files may… Read More »
