pngquant is a PNG compressor that significantly reduces file sizes by converting images to a more efficient 8-bit PNG format with alpha channel (often 60-80% smaller than 24/32-bit PNG files).
I can see how that is relevant to things like screen shots[1], but I'm not sure, in other instances, why you would want to throw away the extra bits of dynamic range that are in the RAW camera format or might be a result of post-processing.[2] "Lossy" means you loose information. You may call it a 'more efficient use of space' if you don't care about the accuracy of the image. That being said, when I reduce an image to an icon of 64x64 I fully expect too loose a LOT of detail :-) [1] Or for most of us for whom it is just a decorative back-curtain, not those of us so obsessional as to want to count every hair on her pubes.
