IcoFX is an application designed to create and edit icons for Windows systems. In addition to standard tools such as shapes, brushes, markings, sprays and fillings, the program provides more than 40 ready-made effects that can be done on the created graphics (adding shadows, optical reflections, colour changes, etc.). The maximum resolution supported by IcoFX for icons is 256x256 pixels, also with alpha channel support (transparency).

In addition, the application offers the function of capturing icons from external 32-bit applications, DLL files and the option of importing and exporting favorite images to icon format. Another useful option offered by IcoFX is the ability to define and store your favorite colors. The program also includes a tool for mass capturing icons from the application and replacing icons with images and vice versa.
