This specialized icon editor is a very complete tool to work with this kind of images, allowing us to create icons for any platform, edit any of the ones that are stored on our hard drive (with the possibility to import any compatible pack) or create icons from a screencapture or other images.
The application is compatible with GIF, JPG, BMP, PNG and PSD. The application also has an icon administrator, thanks to which we will always be able to have our icon collection organized.
Another interesting feature of this program is that it includes a direct access to the developers website, where we will be able to download packs with all kinds of icons, thus, we will be able to use these packs as base images to create our own packs of icons.
Download IconWorkshop and you will have at your disposal one of the best tools to create and edit icons.
