Discover a world of information in digital photos

Digital photographs are full of information that we don't usually see, and JPEGsnoop can extract this for us.

Much of this information is not interesting, but JPEGsnoop uses it to see whether a photo has been altered at all. Want to know if a picture has been retouched? This will tell you. Want to know what program was used to edit a picture? You can find that out too. All you have to do is click the open file button, choose the picture, and moments later you'll have a very lengthy analysis.

Scroll to the bottom to read the assessment, which will be graded from Class 1 (definitely processed/edited) to class 4 (uncertain if edited or original). Apparently it's difficult to be certain if a photo is "original", but easy to ascertain if it has been tampered with.

Of course, most digital pictures have been compressed at some point, and editing in Photoshop has more or less become a norm, but it's still interesting to look at. The image reports are too technical, and not presented in a very user friendly way, but the conclusions are clear enough.

JPEGsnoop is a powerful analyzer, and if you're interested in the origins of a digital photo it will give you a wealth of information.

JPEGsnoop reveals everything about your digital photos.

JPEGsnoop is a free, portable detailed image decoder that examines any file type containing JPEG compressed images and reports a wealth of hidden information. Can even be used to determine the source of an image or whether it has been edited. Opens .JPG, .THM, .AVI, .DNG, .PDF and extracts embedded JPEG files. JPEGsnoop reports countless details, including image quality, EXIF / IPTC metadata, huffman table decode, etc.
