PNGBatchCompressor mainly used for compressed app icon design materials, etc In order to achieve the purpose of reducing the size of the app install package.
PNGBatchCompressor 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!
The conversion reduces file sizes significantly (often as much as 70%) and preserves full alpha transparency.
