Alphasplit

Color and alpha, separated

Only for Mac

Free

Mac

Alphasplit separates an image with transparency into its two parts. You get an alpha mask and a dilation image, where the colors at the edge are extended outward into the transparent area so no empty pixels remain. Drop in a file, see both results immediately, export them as PNGs. Useful anywhere a pipeline wants color and transparency as separate maps: game engines, shaders, compositing, and print. The extended edges prevent the dark or white halos that show up when a transparent texture gets scaled or filtered. Everything happens on your Mac. No account, no network.
