Each picture in an ICO file has its ICONDIR ("Icon directory") structure, which is followed by a contiguous block of all the image bitmap data (which may be in either Windows BMP format, excluding the BITMAPFILEHEADER structure, or in PNG format, stored in its entirety).
How do ICO files work?
Images in ICO files are pixel-based and have a maximum resolution of 256 x 256, 24-bit colour, and 8-bit transparency. For Windows users to connect an image with an application, ICO files provide a handy location to store and scale the images required to display the icons.
ICO file opening instructions
An ICO file can be opened, edited, and created with Windows IconMaker. CorelDRAW is a great tool for producing, editing, and reading ICO files. Use our online ICO Converter to convert ICO files. To use specific images as icons or to store the icon image in an editable or portable format, ICO files are frequently converted to and from other file types.
