PNG2ico converts PNG files to Windows icon resource files. If you're looking for a program to create a favicon.ico for your website, look no further. The program is extremely simple to use. To create a favicon.ico that contains a logo in the resolutions 16x16 and 32x32 (an icon can contain multiple images of different sizes, but a single 16x16 image is enough for a favicon), you would use a command like the following: png2ico favicon.ico logo16x16.png logo32x32.png
