Best UI Icon Libraries

June 20, 2023 - Reading time: 15 minutes

In UI design, iconography plays a crucial role. Icons convey a message and have a unique brand voice in your designs.

But with so many free and suitable icons available, drawing vectors around could be a waste of time to draw icons for an already established visual metaphor. Also, icons tend to change in product design, where a design system evolves along the project, requiring numerous revisions and manual scribbling. That's why starting with an established icon library is a good idea for any project.

To help you with that, we've gathered our top picks of high-quality free libraries that can easily be dragged and dropped into your project and save your creative hours.
