A WIMP front end for the IJPG command line utility 'jpegtran'

What is TranJPEG?

TranJPEG is a WIMP front-end for the IJPG command-line utility 'jpegtran' and gives easy access to the features of the utility. It allows JPEG images to be transformed in a number of ways in a lossless process.

The transformations include rotation, reflection, smart scaling and transposing images. There is also an AUTO rotate option, which depends on the image containing exif data with orientation information.

TranJPEG allows a selection of images to be transformed in a batch process that occurs in the background.
