ICOGen

A lightweight, GUI based .ico file creator. Supports mixed icon sizes, automatic image resizing and fine-grained control over source images.

Easy Image Sizing

Quickly select the image sizes that'll be embedded into your icon from a list of all sizes currently and previously supported by Windows™ and related tools.

No need to manually create source images for each size--let ICOGen handle the resized-image generation for you.

Direct Source Control

ICOGen gives you total control over which source images are used to generate each embedded image. If you're not picky or not sure which to choose, let ICOGen determine for you.

Fine-Grained Filtering

Not all images are made the same, so naturally not all images will scale the same. 

ICOGen gives you fine-grained control over the filtering used to resize source images. Generate your icons exactly as works best for your situation.

Quick Generation

Once you've built an icon to your liking, you're just a click away from generating and saving to disk.

If you'd like to save your work for later, quickly export an .icogen file which will store all your icon settings and allow you to quickly restore them later by importing. Setup a base icon and easily manage variants by exporting .icogen files with your changes.
