PikoPixel

PikoPixel is a simple and easy-to-use tool to create any icon from scratch with plenty of setup options and no need for prior knowledge of the subject.

The program is organized into several freestanding modules from which to access the creation tools as well as a small viewer, layer tool, main window where the icon is displayed, and even a small widget with tips on how to make the best icon possible.

PikoPixel has multilayer support and unlimited undo, so you can give your imagination free rein with full tranquility knowing that you can go back as far as you need to get rid of changes you don't like.

Plus the program has support for keyboard shortcuts and can even export your original icons in different scales in case you need the same image in several sizes for your projects.
