Simple MS Windows GUI application to create and edit MS Windows Icon (.ico) files, including XP and Vista compatible icons. The source images can be loaded from PNG and BMP formats. PNG translucency is supported.
Still beta, but it works great !!! Tip: Use the x32 version.
VERY simple and straight-to-the-point layout, and it produces an ico exactly to Microsoft's spec. Just be aware that if your ico has a single image with PNG compression (which Microsoft actually requires for 256x256 images), then Windows Photo Gallery will say the ico is corrupt and won't display anything (which is pretty ironic). The ico is NOT corrupt, however. If you use a resource extractor like ResHacker and extract an .ico out of say C:\Windows\system32\imageres.dll, you'll get the same message. The point is that your ico DOES work, and it'll display fine in Windows Explorer and it'll work fine if you use your ico in an .exe. Overall, it's a really great utility that really saved me time.
