Developers need high-definition icons for their applications. Icons have two layers: the icon itself and the mask. If the mask is solid black, the icon is opaque around the image, but if the mask is black only where the icon has color, then the icon is transparent around and within the image.
Icon Mask Maker helps you make the high definition icon, transparent mask, and a transparent PNG icon file with a few clicks. There is no need for complicated applications or drawing skills.
