What is a .ico file?
ICO is a Windows icon container that bundles multiple image sizes and bit depths in a single file so the system can pick the best resolution. Each entry is stored as a BMP-style bitmap or embedded PNG, commonly at sizes like 16, 32, and 48 pixels. It is the traditional format for application and website favicons.
How to use this file
Use an example ICO to test favicon and icon extraction, multi-resolution selection, and converters that build ICO files from PNG sources.
