JPEGsnoop – JPEG File Decoding Utility V 1.4.0

JPEGsnoop – JPEG File Decoding Utility
JPEGsnoop is a free Windows application that examines and decodes the inner details of JPEG and MotionJPEG AVI files. It can also be used to analyze the source of an image to test its authenticity.

Every digital photo contains a wealth of hidden information — JPEGsnoop was written to expose these details to those who are curious.

Not only can one determine the various settings that were used in the digital camera in taking the photo (EXIF metadata, IPTC), but one can also extract information that indicates the quality and nature of the JPEG image compression used by the camera in saving the file. Each digical cameras specifies a compression quality levels, many of them wildly different, leading to the fact that some cameras produce far better JPEG images than others.

JPEGsnoop will open and attempt to decode any file that contains an embedded JPEG image, such as:

* .JPG – JPEG Still Photo
* .THM – Thumbnail for RAW Photo / Movie Files
* .AVI* – AVI Movies
* .DNG – Digital Negative RAW Photo
* .CRW, .CR2, .NEF, .ORF, .PEF – RAW Photo
* .MOV* – QuickTime Movies, QTVR (Virtual Reality / 360 Panoramic)
* .PDF – Adobe PDF Documents

Look at a few of the many possible uses for the JPEGsnoop tool.
