What is a ICO file?

ICO is a file format used for icons in Microsoft Windows. It stores one or more small images in different sizes and color depths, allowing Windows to scale icons across different UI components.

ICO files are essential for desktop software and websites (as favicons), and they can include both bitmap and PNG-based images.

How to open ICO files

ICO files can be opened with Windows built-in image viewer, Paint, or advanced tools like IcoFX, GIMP, and Photoshop (with plugins). macOS may require conversion first.

If you need to convert ICO to PNG or JPG, AnyConv makes it simple to do so online in just a few clicks.
