KIconEdit is described as 'tool designed to help creating icons using the standard color palette' and is an app in the Photos & Graphics category. There are five alternatives to KIconEdit for Windows, Online / Web-based, Android and Android Tablet. The best alternative is IcoFX. It's not free, so if you're looking for a free alternative, you could try Pixelesque or Favicon.cc. Other great apps like KIconEdit are IconWorkshop (Paid) and X-Icon Editor (Free).
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.
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.
