Icons are an important part of user interfaces, which are used in expressing objects, actions, and ideas. They are used to communicate the core idea and intent of a product or action. So, they bring a lot of benefits to user interfaces.
Icons are used to present information visually. For example, Instead of writing a text message of instruction over a small button, you just design an icon representing that message. That reduces the space that could have been taken by text message and it provides a cleaner and concise user experience.
So, primarily icon is used to communicate the message very rapidly and effectively.
