KIconEdit!

IcoFX is an 51 awards winning icon editor. It is an all-in-one solution for icon creation, extraction and editing. It is designed to work with Windows XP, Windows Vista, Windows 7 and Macintosh icons supporting transparency.

IconWorkshop is a professional tool designed to create, extract, convert, manage and redistribute icons for Windows, Mac OS, iPhone, and Android up to 512x512. No complicated settings, no more pixel-by-pixel icon making. All has been designed to let you be productive and get professional results in minutes (using image objects for instance).

Pixelsque's goal is to be as simple as possible, while still retaining many powerful features. It works like any standard pixel art editor, with a pen, eraser, and shapes. Pinch zoom and two finger drag can be used to move around the image from anywhere. Lesser-used functions such as save/open/new, and others can be found in the menu, saving valuble screen space on phones, and allowing easy access on tablets. It fully supports all Android devices from low-end phones to high-end tablets.
