PngOptimizer
March 28th, 2009 by ReinderWhile doing some internet research for a future post on webcomic image optimization, I came across a blog post that claims a GPL-licensed Windows program called PngOptimizer outperforms PNGout by about 8% of the original uncompressed file size. I was a bit skeptical as the quoted compression percentage for PNGout in the post seems a bit low to me (typically for me, PNGout takes out 8 to 10% of the original file size) but I downloaded and tried it anyway. I tested it on the web files for Feral and while I don't see PngOptimizer outperforming PNGout on those, it does perform very well and is easy to use. Windows-only, though. I'll investigate more when I get home and have a better set of testing files at my disposal.
Also, here's how to enable using PNGout directly from your Windows Explorer window. Neat, if you like registry hacking.
