PNGOUT optimizes the size of .PNG files losslessly. It uses the same deflate compressor I wrote for KZIP.EXE (see below). With the right options, it can often beat other programs by 5-10%. That includes pngcrush -brute, optipng -o7, advpng -z4, etc.. PNGOUT is a great tool for optimizing the size of web pages or squeezing game content onto mobile devices. Almost all .PNG files on my website were optimized with PNGOUT.

$tools = Split-Path -parent $MyInvocation.MyCommand.Definition
$content = Join-Path (Split-Path $tools) 'content'
$target = Join-Path $content 'pngout.exe'

In cases where actual malware is found, the packages are subject to removal. Software sometimes has false positives. Moderators do not necessarily validate the safety of the underlying software, only that a package retrieves software from the official distribution point and/or validate embedded software against official distribution point (where distribution rights allow redistribution).
