Input sRGBA8 Image Output sRGBA4 Image
Drop image here

Drop an image on this page to quantize it to sRGBA4 PNG, which will match quadplay's input requirements and compress better than sRGBA8.

I recommend the free tools ImageOptim for MacOS, PNGGauntlet for Windows, and TriImage for Linux for further compressing the resulting PNG files by up to 90%.
