Image to ICO icon format

What is the ICO icon format?
The ICO icon format is an icon file format that is common on Windows systems. Icon files in this format can store icon files of single patterns, multiple size, and multiple colors. Each icon is actually a collection of multiple pictures in different formats and may contain a certain transparent area. ICO icons have good compatibility and compressibility, and can simultaneously meet the needs of devices with different resolutions and sizes, so they are widely used in Windows systems. In addition to being an icon for applications and folders, ICO icons can also be directly used as a Favicon logo on websites. These Favicon logos will be displayed in front of the browser's favorites, address bars, and tab titles to distinguish different websites. When making ICO icons, you usually need to consider the optimal size for different platforms. Common size include 16×16 (small icon), 32×32, 48×48, 24×24, 64×64, 128×128, etc. It should be noted that although the ICO icon format is very common on Windows systems, different icon formats (such as ICNS) may be used in other operating systems (such as Mac OS). In addition, when processing ICO icon files, you can use Windows Image Manager or tools such as ACDSee to preview and edit them. If you need to edit icons, you can also use special icon making tools such as IconCool Editor. In short, the ICO icon format is a common icon file format on Windows systems. It has good compatibility and compressibility and is suitable for device needs of different resolutions and sizes.
