Another day, another image optimization tool. This one is called ‘RIOT’, and while it only runs on Windows it enables a nice side-by-side view of your images so that you can interactive tweak parameters and compare the result to the original image.
Radical Image Optimization Tool (RIOT for short) is a free image optimizer that will let you to visually adjust compression parameters while keeping minimum filesize.
It uses with a side by side (dual view) or single viewinterface to compare the original with the optimized image in real time and instantly see the resulting file size.
Could be a great tool for folks looking to maximize individual images (webmasters for example hoping to optimize bandwidth).
