[FILE:508:descriptions/desc.primary]
OptiPNG is a PNG optimizer that recompresses image files to a smaller size,
without losing any information. This program also converts external formats
(BMP, GIF, PNM; TIFF support is coming up) to optimized PNG, and performs
PNG integrity checks and corrections.

The idea has been inspired from pngcrush, and is explained in detail in the
PNG-Tech article "A guide to PNG optimization". The implementation is
carried forward in OptiPNG, which offers a faster execution per trial, and
a wider search space.
