Expressive 2D design icons
Not every interface needs a neutral symbol set. These collections use softer, bolder, or more geometric shapes when the visual language of a product or digital layout needs a stronger point of view.
Flex Smooth Design Icons
Flex Smooth Design Icons uses curving, modern shapes built on a 14px grid and provides eight styles. The range gives UI designers a way to keep a coherent system while choosing a softer visual direction.
Plump Friendly Design Icons
Plump Friendly Design Icons features chunky shapes with a warm, hand-drawn quality inspired by cartoons. It suits apps and digital layouts that call for a friendly icon treatment instead of a strictly neutral UI style.
Sharp Geometric UI Icons
Sharp Geometric UI Icons combines pure geometry with bold structure for a brutalist, high-tech feel. Its vector and SVG-related tags make it a focused option for interfaces and visual systems built around sharp, minimalist forms.
How to choose the right icon set
Start with the project’s visual language: choose a grid-based system for broad UI coverage, an outline collection for restrained controls, or a distinctive style for more characterful layouts. Then compare category breadth, icon count, and whether fill, stroke, or multiple styles best match the interface. Explore the Craftwork catalog for more design assets for your next project.
