I do. Lossy PNGs work great for images with not a lot of colors. I use pngquant and optipng a lot in my work to compress a lot of PNG images with practically no visual quality loss.
For very colorful images, lossy (quantized & dithered) PNGs just don't work, though. They just end up looking nasty with larger filesizes than what high quality JPG gives you.
- pornel 12y agoThere's also a method for true-color lossy PNGs that blurs instead of dithering: https://speakerdeck.com/pornel/lossy-png-for-true-color-images-velocity-conf-eu-2014 https://speakerdeck.com/pornel/lossy-png-for-true-color-imag... (https://github.com/pornel/mediancut-posterizer https://github.com/pornel/mediancut-posterizer). It's not as efficient as PNG8, but still better than nothing :)
