JPEGsnoop1.8.0

JPEGsnoop is a tiny and portable application that shows technical information on some file types, mainly images. It comes bundled with several settings that cater to advanced users.The tool offers support for JPEG, THM, AVI, MOV, DNG, RAW and PDF files.Since installation is not a prerequisite, you can drop the executable file to a custom directory on the HDD and just click it to run. It is also possible to save JPEGsnoop to a USB flash disk or similar storage unit, in order to run it on any machine with minimum effort and no previous installers.An important aspect to take into account is that the Windows registry does not get updated with new entries, and files are not left behind on the HDD after program removal.The interface is not particularly attractive but easy to work with. Adding a file to the list is done using either the file browser or drag-and-drop support.Details include the file name and size, start offset, identifier, version, density, thumbnail size, and others. Images can be previewed on the bottom part of the screen. You can save the log to file for further scrutiny, process an entire folder, specify the starting file offset, or use a search function when dealing with large data amounts.Other options of JPEGsnoop let you alter the image channel and zooming level, set overlays, calculate the file offset for an MCU, export JPEG and TIFF, update the database with compression signature, and so on.The tool has a good response time and minimal impact on computer performance, using low CPU and RAM. We have not encountered any difficulties when testing it, since JPEGsnoop did not hang, crash or pop up error dialogs.Although it is not particularly intuitive, the program should be helpful to users with heavy experience in graphics editing applications.
