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 compression levels. It also performs automatic bit depth, color type and color palette reduction where appropriate and can correct some data integrity errors in input files.
