Understanding Apple Touch Icon

Apple Touch Icon is a feature in mobile web development that allows websites to have a custom icon when saved to the home screen of iOS devices. It provides a visually consistent and branded experience for users. The recommended specifications for Apple Touch Icons include a square image with dimensions of 180×180 pixels for high-resolution devices and 152×152 pixels for older devices.

A precomposed PNG fix is a solution to overcome the display issues associated with Apple Touch Icons. By using a precomposed PNG format instead of the default rendering, you can achieve superior clarity and eliminate the problem of blurry or jagged icons.
