What is ICO?

ICO is the icon file format used by Microsoft Windows for application icons and website favicons. A single ICO file can hold several image sizes and color depths at once, so the system picks the best one for each context. It remains the standard format for the favicon displayed in browser tabs.

ICO supports both lossy and lossless compression, so file size and fidelity depend on how each file was encoded. It supports transparency.

ICO was developed by Microsoft.
