Top 50 Free Flat Icon Sets for UI Design

Flat design icon sets are a popular design trend in which icons are created with a flat, minimalistic style that eschews the three-dimensional look of more traditional icons. They typically use simple shapes, bold colors, and clean lines to create a clear and easy-to-understand visual language.

Flat design icon sets use a limited color palette and simple shapes, they are often more visually consistent and cohesive than more complex icon sets.

Many flat design icon sets are available for free, making it easy for designers and developers to incorporate them into their projects. They can be used in a wide range of applications, from websites and mobile apps to print materials and marketing campaigns.
