PureJPEG is an easy to use, high performance utility to remove unnecessary data from images you email or post on the net, without affecting the image quality whatsoever (no decompression/recompression is performed in the filtration), removing such extraneous information as:
Digital camera technical data (EXIF)
Comment blocks
JPEG thumbnails
Application blocks
While you should never use this application on your personal image archive (where this information may actually serve a purpose in some scenarios), it is generally worthwhile to purify JPEG files when sharing images, or when posting images online.
PureJPEG is a command line application, and has three primary methods of execution.
purejpeg.exe : When no parameters are provided, files to process are taken from the console input, separated by linefeeds, until an EOF (Ctrl-Z) is encountered. Files are overwritten. This is most commonly used to pipe file lists between applications
purejpeg.exe [infilename] : When one parameter is provided, the parameter is used as the input file, and is subsequently used as the output file -- the original file is overwritten with the filtered output
purejpeg.exe [infilename] [outfilename] : When two parameters are provided, the first parameter is used as the input file, and the second is used as the output file
