DESCRIPTION:
JPEG files generally contain 'extra' data that isn't used by web 
browsers or most image viewers. This extra data takes time to 
download when viewing a web page, and takes additional hard drive 
space. Most of the time it is safe to remove this extra data. 

jStrip removes this extra data. It does not have to recompress the 
image data, so there is no image quality loss. It will remove 
thumbnail data that is not usually seen.

jStrip can also do simple file renaming of your JPEG files.
