Icons2Pics is a simple application that will allow the user to convert any number of Mac application icons (512 px x 512 px or 128 px x 128 px) into graphic images of various sizes at a time.  All you have to do is drag and drop applications directly onto the listbox, choose an export format and select image sizes and an export destination and then click on Export. You can set default export format, image sizes and destination folder in Preferences. So you could just import applications and then click on Export right away.
