2,480 free bold-weight icons from the Solar icon family. Heavy, confident fills that command attention in any interface. Open source under MIT license, delivered as optimized SVG for web and app projects.
Some interfaces need icons that whisper. This is not that set. Solar Bold delivers 2,480 free icons with thick, solid fills that plant themselves firmly in your layout and refuse to be overlooked. These are the icons you pick when the design needs presence, when a subtle outline just will not carry the weight of the action it represents.
Built for impact
Bold icons work hardest in contexts where attention is scarce. Mobile navigation bars where users are multitasking. Call-to-action buttons that need visual reinforcement. Dashboard widgets where status needs to register at a glance. Onboarding screens where each step icon should feel important. The heavier fill ensures recognition even when users are scrolling fast or viewing from a distance.

2,480 free icons across dozens of categories

Five weights, one system
Solar is not just one icon set. It is a complete weight system. This bold variant sits at the heaviest end, but you can mix and match with Solar Linear for standard outlines, Solar Outline for a lighter touch, Solar Broken for a distinctive broken-line style, and Solar Duotone for a two-tone approach. Every icon exists in all five weights, so switching styles mid-project takes seconds.
