website = [http://optipng.sourceforge.net/ optipng.sourceforge.net]OptiPNG is an open source
command line computer program that reduces the size of PNG files. The compression is lossless, meaning that the resulting image will have exactly the same appearance as the source image.The main purpose of OptiPNG is to reduce the size of the PNG
IDAT data stream by trying various filtering and compression methods. It also performs automatic bit depth, color type and color palette reduction where possible, and can correct some data integrity errors in input files.Besides PNG files, it allows input from BMP, GIF and PNM files, but the output file format is always PNG.
