VG JPEG Recovery Server

Using our JPEG Recovery Web Application

Our product VG JPEG Recovery Server restores your damaged JPEG images. This server application is the result of united work of our software developers and our JPEG experts and subject to continuous improvement. VG JPEG Recovery Server restores a lot of specific and different JPEG image errors and can be considered as unique in the world. On this website we have listed and explained some recovery outputs of VG JPEG Recovery Server.

If you are a company and interested in buying or licensing our product, please contact us.

Multiple image output

JPEG files can be damaged in a number of different ways. The main task is to repair the error, of course. But this work only can be done, if one knows what error there is to be reconstructed at all. VG JPEG Recovery Server tries to recover different error types fully automated. Therefore often multiple output files are created out of one single input file. As an outcome, VG JPEG Recovery Server displays all possible 'reconstructions' of an image within a common image list, so the user can select the image that was recovered correctly. However, if the user selects multiple images of the common image list, VG JPEG Recovery Server only charges one single file.

Image with low resolution

Select 640 x 480 Small resolution. Click on preview!

As we have described at JPEG errors, JPEG files often contain several pictures, each with a specific resolution. Even if the native resolution of an image is lost forever, images in lower resolutions could be recovered though. This is based mainly on the hierarchical buildup of JPEG file format or embedded thumbnail images. We offer a discount of 50 percent for images with a resolution less than 800 x 600 pixel.

Incomplete image

Select 2736 x 3648 59%

Sometimes an image can´t be recovered completely because a part of the image information (data bytes) is definitely lost. Lost information will never be 'repairable' by any recovery program, because one can´t 'create' lost information from close to scratch. Though one can try to recover the damaged part that still exists. VG JPEG Recovery Server recovers all JPEG image parts that still exist, if a picture is not recovered completely, it gives a discount in proportion of the lost part. For example, if only half of an image can be recovered, VG JPEG Recovery Server gives a discount of 50 percent.

Recovery of color errors

Select 2736 x 3648

As we have described at JPEG errors, single bit or byte errors within a JPEG stream lead to color errors. This type of error often appears with damaged data carriers or files that are created by recovery software. We offer a service to restore such errors that is worldwide unique. No other recovery software is able to reconstruct damaged JPEG streams the way we do.

Because JPG color damage is especially hard to repair, a recovery is not possible fully automated. The normal product recovery often leads to image areas that have different brightness values (see image below). In addition, all image colors seem to be 'bleached'. Therefore, VG JPEG Recovery Server gives a discount of 25 percent for images that are recovered this way.

Recovery with Pattern Files

As we have described at JPEG errors, images with a lost or damaged JPEG header can be recovered by using file headers of other, not damaged, JPEG files (so-called 'pattern files'). VG JPEG Recovery Server is able to repair JPEG files with the help of other JPEG headers; nevertheless this procedure is very complicated and not as easy as it sounds. The used pattern file must satisfy the following criteria:

• The file can show any theme. I.e. it is not important what the pattern image actual shows.
• The file must be valid and not damaged.
• The file must be created by the same camera.
• The file must have the same resolution.
• The file should be recorded with the same camera configuration (compression, camera settings etc).

If the user starts a recovery, all available JPEG headers from the pattern file, as well as from the input image itself, are used to reconstruct the input image. This can lead to multiple output images with only one valid result and other 'shifted' image results:

If the common image list only shows the strange looking 'shifted' images, than the user has selected the wrong pattern file! In most cases, the resolution of the pattern file was wrong. In this case, the user has to create a new upload and has to select the correct JPEG file as pattern file.
