PROGRAM:
NAME
OptiPNG - Optimize Portable Network Graphics files
SYNOPSIS
optipng [-? | -h | -help]
optipng [options...] files...
DESCRIPTION
The OptiPNG program shall attempt to optimize PNG files, i.e. reduce their size to a
minimum, without losing semantic information. In addition, this program shall perform a
suite of auxiliary functions like integrity checks, metadata recovery and pixmap-to-PNG
conversion.
The optimization attempts are not guaranteed to succeed. Valid PNG files that cannot be
optimized by this program are normally left intact; their size will not grow. The user may
request to override this default behavior.
