PNG can be a lossy format

Admittedly before I read this feature page on the ImageAlpha app site, I didn’t fully appreciate how PNGs could be saved effectively in a lossy or compressed format. That’s what JPEGs were for, right? But I was wrong. If you use a smart algorithm and compressor like on the free ImageAlpha app, PNGs can get their size easily stripped in half. An alternative to the TinyPNGs of the world.
