What is an ICO file?

ICO files contain pixel-based images that can have up to 256 x 256 pixels, 24-bit color, and 8-bit transparency. ICO files offer a convenient place to store and scale the images needed to display the icons so that Windows users can associate an image with an application.

How to open an ICO file?

Use Windows IconMaker to open, edit, and create an ICO file. CorelDRAW is an excellent program for opening, editing, and creating ICO files. To convert ICO files, consider using our online ICO Converter. Often, ICO files are converted to and from other file types to use certain images as icons or to save the icon image into an editable or portable format.

A popular program for manipulating ICO files is GNU Image Manipulation Program (GIMP). ICO is supported by Mac, Linux, and Windows operating systems. Other programs that can open ICO files include Microsoft Paint, Apple Preview, or IrfanView.
