Editors' review

JPEGsnoop is a free image decoder that wrings every drop of data that can be extracted from JPEG images. It's compact and fully portable, so you can take it along with you on a USB drive or other memory device and run it from any compatible Windows machine without having to install it. It can open not just JPEGs but also AVI, DNG, PDF, and THM files, and it also extracts embedded JPEG files. As for the data it extracts, we didn't know that JPEGs contained so much information.

We extracted JPEGsnoop's compressed download and opened the program's plain but businesslike user interface. This program offers online assistance via the Help menu, but its old-school Windows functionality basically explains itself. We clicked the File menu and selected Open Image. Our image appeared as a thumbnail in the bottom preview panel, while the main view was filled with information so detailed that much of it won't be of use to anyone but graphics professionals, unless you can make good use of the histogram stats and code lengths displayed in various Huffman Tables. But this tool is clearly aimed at professional users like photographers, Web designers, and programmers. It offers versatile features such as the ability to process batches of files, save log files, and export JPEG and TIFF files. JPEGsnoop offers many sophisticated options; for instance, we were able to select between a fast, low-resolution process and a slower but more thorough and accurate scan. Among the program's more prosaic options are selectable tool tips known as Coach Messages.

For those who need it, JPEGsnoop is just the thing, especially since it's compact, portable, free, and easy to use.

    "Very impressive analysis of photo files"

    February 18, 2010   |   By MillSquareSoftware

    Version: JPEGsnoop 1.4.1

    Pros

    The producer of this software clearly has a deep understanding of how photo files are put together.

    Cons

    No real cons.

    Summary

    Would be fantastic if a future version could include some tools to repair some of the errors you sometimes get with corrupted digital photos but I imagine that would be very complex to do.

    "Seems to work fine"

    July 11, 2009   |   By Jim Harmon

    Version: JPEGsnoop 1.4.1

    Pros

    It's quick and lists a lot of information

    Cons

    I haven't seen anything bad about it

    Summary

    I'm no metadata expert, but this program reveals a lot of header information. For all I know, there could be a lot missing. Even still, I feel this program is worth a look-see.
