ICO (Icon File) is a .ico file format used by Microsoft Windows OS. It is the file format for saving images used in various “icons”on Windows based computers. An icon is a small graphic image, usually with text indicating what the file contains such as a home folder or a digital camera. Icons are used to enhance the user experience by giving users quick and easy access to particular functions. ICO files are usually created from a medium to large size image, and then compressed down to the size of an icon.
Technical Details
Originally ICO files were limited to 16×16 pixel in size. This restriction has been lifted in modern versions of Windows, although they still remain small in size at 32×32 pixels and less. The current ICO format allows support for 32-bit RGB colours within the icon dimensions, which enables more detailed images within the same space. Additionally, more colours can be used through animation of multiple layers. Compression within.ICO files is done with the help of PNG or BMP. Hence, saving storage space on systems where icons are used frequently.
Similar File Extensions
There are other file formats which are similar in application, such as .icns, .cur, and .dll. All these formats can display images, but their primary use case differs depending on the system which is using them.

After installing the required software, the operating system will usually automatically associate an unknown file type (in this case .ICO) with the new application. If this does not happen, we can help the system a bit by selecting the software for it, which it should always use to open files with the .ICO extension.
When choosing the software we can select the system to use this software every time.
Remember!
Using it for the first time it is good to check whether the .ICO file opened in the application can be read by us and opens in a way that allows us to use it. If everything is in order, select this option the next time you open a file with the .ICO extension. However, if the file has not opened correctly, we have to look for a different software, with which we can open files with the .ICO extension. Select a different software from our list and install it on your computer. After the software is installed, repeat inspection openings of a .ICO file. Sometimes you have to repeat the operation several times.
Other instructions
If none of the programs listed by us to work with the .ICO file has not meet your expectations, you can try searching other websites. But remember to avoid downloading programs "that can open any file". These applications not only have very limited functionality, but may also expose you to expense tens of dollars when purchasing a license.
In the vast majority of cases you will find the program dedicated to support the .ICO file, or any other file format. In addition, there is a chance that it will be a free program, and its functionality (concerning the .ICO file) will be extended to the maximum.
It is also good to check
- if the .ICO file has no errors
- or if it has been copied (or downloaded by the browser) thoroughly
