Red Sweater Blog – Fixing PNGs
I was alerted by @spittingcat on Twitter to an impressive, free tool called ImageOptim. The author argues that his optimization technique for PNGs results in smaller, faster-loading images than Apple’s, while conforming with the PNG standard. I ran some of my PNGs through the tool and it shaved 30-40% off the size. I’m going to strongly consider using this tool, and disabling Apple’s PNG optimization for my projects.
