Become a JPEGREPAIR NINJA yourself Recover, Fix and Repair corrupted JPEG photos
The JPEG-Repair Toolkit consist of two tools that can help you repair corrupt photos: JPEG-Repair a repair utility and JpegDigger a recovery tool. The tools were developed based on my experiences with repairing photos for my photo repair service, initially for my own use. This is why they may feel more as tools rather than polished products. JPEG-Repair can help you repair existing photos. JpegDigger was developed because I found that corrupt photos were often the result of incorrect undelete or photo recovery or due to file system errors.
If purchased the license key can be used to unlock both tools. JpegDigger can also be purchased as a stand-alone tool.
Use the trial version to determine if JPEG Repair Toolkit can repair your photo(s) prior to purchasing.
|For home/personal use – You’ll be repairing your own photos||Technician license – You’ll be repairing your organization’s or 3rd party photos|
Additional taxes, including VAT or sales tax, may apply depending on your local regulations.
[Trials only save scaled down photos in BMP format. These are generated from the full size JPEGs.]

Repair your corrupted photos
I have been offering a JPEG repair service for several years. Learning from that I have created a utility that addresses most common issues with corrupted and damaged JPEG files, JPEG-Repair Toolkit. JPEG-Repair Toolkit allows you to repair your corrupt photos yourself.
Currently JPEG-Repair supports following photo formats (to some degree*):
JPEG, NEF*, CR2*, CR3*, RAF*, CRW*, ORF*, ARW*, SRW*, PEF*, RW2*, DNG*, TIFF*
Repair corrupted JPEG headers
JPEG-Repair is an easy to use alternative for replacing corrupted headers with a hex editor. JPG-Repair can repair corrupt JPEG headers using a reference or sample file. It is an easy alternative for replacing a corrupt header with an intact one using a hex editor. A typical symptom of a corrupt header is that the JPEG file can not be opened at all. Windows explorer does not show preview thumbnails and different viewers and photo editors may show different error messages.
Repair corrupted and distorted JPEG image data
Patch (edit) raw JPEG image data with visual feedback. Corrupt data in the actual JPEG image data can have many effects, ranging from an abrupt change in color or brightness, up to the image appearing to be suddenly cut-off. The latter often results in a grey block or a solid color block. Image data can also abruptly shift to the left or right causing different parts of the image to be misaligned. With help of JPEG-Repair it often possible to remove the bad data resulting in a dramatic improvement of the photo. Be warned that this requires patience and a bit of luck.
Patching also allows you to patch a header on a block of JPEG data so that even corruption that spans the header + part of the JPEG data can be addressed. As an example I have even been able to repair JPEGs that were victim of STOP Djvu ransomware using JPEG-Repair.
Recover JPEG data from corrupted RAW photos
JPEG-Repair can help you get the JPEG data from RAW files such as Canon CR2 and Nikon NEF files when ‘normal’ tools that are normally up to this job can not. Depending on the camera manufacturer those JPEGs are full resolution JPEG files. Are RAW photos from you camera not supported? Send me a few samples and I’ll add support for those as quickly as possible! My aim is to support every RAW format out there!
JPEG Repair Toolkit extracts embedded JPEGs as they are. If embedded JPEGs are corrupt themselves then extracted JPEGs are too. In some cases JPEG-Repair Toolkit may be able to repair these JPEGs.
JPEG Repair toolkit features Features:
- Repair corrupt and damaged JPEG files
- Fix corrupt JPEG header
- Repair Invalid JPEG markers
- Repair damage due to bad sectors
- Improve corrupt JPEG image data by patching JPEG bit stream with visual feedback
- Recover JPEG data from corrupt RAW photos such as CR2 and NEF
- Does not re-encode JPEG image so original quality is preserved!
- Preview of repaired file
- Does not alter original files
- No need to upload photos to remote servers
- Free version shows previews + saves low resolution examples.
|Thank you Joep for all the support you have given users here that have given you feed back. I am a professional photographer and had a few corrupted files from years ago. Worked like a champ! Will recommend to friends. – Amanda H @ GOTD|
Most of the simpler repairs only require you to select the file(s) you need to repair and click ‘repair’.

For repairing corrupted headers JPEG-Repair needs a ‘sample file’. The reference or sample file should be taken with the same camera as the corrupt image(s). Also, the settings (resolution, quality and orientation) of the sample file need to match the corrupt files. If unknown then you would need to experiment by taking different shots with different settings using the original camera (same brand and type).
*RAW file support!
Technically JPEG-Repair does not repair these files. Functionality is limited to extracting half or full sized JPEGs from these file types. However, JPEG-Repair is able to process RAW corrupt files while other tools able to extract JPEG from RAW often rely on the file to be intact.
Can my photo be repaired?
Of course this is the question I get asked most. The major contributing factor is of course, is if the actual image data present in the file. JPEG-Repair can’t make a photo out of thin air. So, a photo can be repaired if (a large portion) the image data is present. The easiest way to determine if data is present within a file, and if this data is compressed JPEG data is by looking at entropy. Entropy, in relation to our subject is the amount of chaos within the file data. JPEG-Repair displays this value in the left upper corner of the screen.
If entropy looks okay, then it is likely the photo can be repaired to at least some degree.
If entropy is too high or low then the data within the file is probably not JPEG data. One situation where I see this a lot is when examining JPEG photos that were recovered or undeleted. Although such a file probably can not be repaired it is sometimes possible the recovery can be improved. This is why I wrote JpegDigger and why your JPEG-Repair license works with that utility too.
The idea for this tool is not original and basic concept was ‘copied’ from Wim Vanmaele’s utility repair-jpeg. I can’t find the original source for this program but it can still be found here: http://directory.s2services.com/jpg-bmp.htm. I read this and tried this tool which I found to be incredibly difficult to use, which is why added this functionality to JPG-Repair:
“..During my testing, I discovered that by adding one byte at a certain position in the jpg file the corrupted picture was restored. So all we need is a tool that would add a byte at a user-defined position. JPEG-Repair, the program I wrote, will allow you to do this..”
If you have other issues then feel free to contact me. Send me your sample file + some corrupted files so I can examine them.
