High Quality Content by WIKIPEDIA articles! Pngcrush is a free, open source command-line utility that reduces the size of PNG files losslessly that is, the resulting "crushed" image will have the same quality as the source image. The main purpose of pngcrush is to reduce the size of the PNG IDAT datastream by trying various compression methods. However, pngcrush can also be used for various manipulations of PNG images, such as changing the bit depth. pngcrush offers an optional "-brute" argument which attempts to brute force the crush when set: rather than use one of a few common methods to crush the file, it will try all of them. The main use of pngcrush is for reducing the size of the image data contained in the IDAT section. PNG uses DEFLATE compression which can vary in speed and compression ratio, from nearly no compression at all but at very high speed to the very good compression ratio, albeit at a lower speed.
