JPG-Repair Toolkit allows you to recover data from corrupted RAW photos (JPEG). RAW photos contain the raw, ‘undeveloped’ sensor data from high-end digital cameras such as DSLRs from Canon, Sony, Nikon, Konica, Olympus etc.. JPG-Repair Toolkit can process multiple RAW files in batch.
Commonly these RAW photos embed one or more JPEGs: a low resolution thumbnail, a medium resolution preview, and in many cases a full frame preview.
Using JPG-Repair Toolkit you can extract the full frame preview. The latter is true even if resolution for the RAW photo was set to a lower value. There are tools available to extract this data from a RAW photo, but typically they parse intact files and refuse to work on corrupted files.
Other ‘repair’ software available only extracted either thumbnails or medium sized previews during my testing and as per customer’s comments (“I just purchased Stellar and all it does is save the thumbnail”). Following formats are currently supported:
Technically JPG-Repair Toolkit does not repair RAW files, it extracts JPEGs already embedded!
