pngcrush is a
free, open source command-line utility for optimizing PNG image files.
It reduces the size of the file 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 combinations of compression methods and delta filters. However, pngcrush can also be used for various manipulations of PNG images, such as changing the bit depth, removing unwanted ancillary chunks, or adding certain chunks including gAMA, tRNS, iCCP, and textual chunks.

Pngcrush is open source and may be used, modified, and redistributed by anyone without paying a fee. The license, embedded in the file pngcrush.c, is equivalent but not identical to the libpng license found in the libpng file png.h.
