Bitmap to Icon Wizard is an easy-to-use program to create Windows icons from bitmap (.bmp) files. It supports output with 32-bit alpha-channel transparency as well as 24-bit, 8-bit, and 4-bit. The generated icon file (.ico) can contain up to 5 different icon sizes (256x256, 48x48, 32x32, 24x24, and 16x16). Bitmap to Icon Wizard requires .BMP input files, so you may need to convert your files to BMP before using this software to generate the icons.
