PNG Icon Generator 1.2.0
PNG Icon Generator is an application for Adobe AIR applications, that generates all 4 icon sizes from a single 256×256 PNG file.
Rather than creating each specific icon size yourself, create one image (256×256 PNG) in your favorite Graphics Editor and use this application to then generate the required icons for you. Simply drag and drop your original image on the application, select the destination folder and click the create button...its as simple as that.
Mac OS X 10.4 or higher. Adobe AIR required.
