软件介绍
Smart PNG and JPEG compression
Optimize your images with a perfect balance in quality and file size.
Uses smart lossy compression techniques to reduce the file size of your PNG files. By selectively decreasing the number of colors in the image, fewer bytes are required to store the data. The effect is nearly invisible but it makes a very large difference in file size!
