This page is intended to provide an explanation of some of the features of the PNG format for non-technical users. As such, it doesn't emphasize PNG features like freedom from patents; those are more of concern to developers. Where programmer information is given, it is principally to explain to the user why various applications may not perform as well as expected. Where performance claims are made--especially compression comparisons with other image formats--we assume that the PNG implementation is at least as good as the best freeware encoders. Note
