RIOT uses dual windows to compare the original image and the optimized image in real time. Since it is all done in memory, it is very fast. By controlling the compression, color number, metadata settings, etc., and then outputting the image (JPG, GIF or PNG format), the image size can be significantly compressed. Supports batch processing, you no longer have to open PS to process small things.
The use of RIOT is very simple. After opening the image, first select the format to be output, and then you need to adjust the parameters. During the adjustment process, you can directly preview the effect. Once the desired effect is achieved, save it. RIOT can be integrated into GIMP and has IrfanView and XnView plug-ins. You can decide whether you want to keep EXIF data. Supports common tools: pan and zoom, rotate, flip, basic image adjustments: brightness, contrast, gamma, invert and more.
