Radical Image Optimization Tool (RIOT for short) is a free image optimizer that will let you visually adjust compression parameters while keeping minimum filesize. It uses a side by side (dual view) or single view interface to compare the original with the optimized image in real time. You will be able to control compression, number of colors, metadata settings and much more, and select image format (JPEG, GIF or PNG) for your output file. RIOT can be integrated as plugin in well known programs like The GIMP, IrfanView and XnView
