picture compressor

To save traffic, the best way is to compress images (compression of photos is not recommended. Major free photo album websites do not limit the photo space capacity, but the traffic is limited...), which can fundamentally reduce the loss of traffic. Of course, the purpose of compressing images is not limited to blogs. Many occasions that do not have high requirements for images also require compression. What's more, RIOT can intuitively adjust the compression parameters while maintaining the minimum file size.
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), you can Obviously compressed image size. 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 the EXIF ​​data. Supports common tools: pan and zoom, rotate, flip, basic image adjustments: brightness, contrast, gamma, invert and more.
