Frequently Asked Questions
What are the best curated icon libraries for UI design?
Lucide, Heroicons, Phosphor Icons, and Tabler Icons are the top curated icon libraries for UI design — all offer clean SVG icons with MIT licensing and React packages. Hugeicons and Eva Icons are strong alternatives when you need larger sets.
What is the best free icon library for web design?
The most popular free icon libraries for web design are Lucide, Heroicons, Phosphor Icons, and Tabler Icons. Each offers SVG icons in multiple styles with clean, modern aesthetics that work well in product UI.
What icon format is best for web projects?
SVG is the best format for web icons. SVGs are resolution-independent, accessible, easily styled with CSS, and have small file sizes. Avoid PNG icon sets for UI work.
Are free icon libraries safe to use commercially?
Most popular icon libraries like Lucide, Heroicons, Feather Icons, and Tabler Icons use the MIT license, which allows free commercial use. Always check the license for each library before using it in client projects.
How many icons do I actually need in a UI project?
Most product interfaces use 30–80 unique icons across navigation, actions, and status states. Start with a library that covers common UI patterns, then add custom icons only where brand differentiation matters.
Can I mix icons from different libraries?
You can, but stick to one library per project when possible. Mixing stroke weights, corner radii, and grid sizes makes interfaces feel inconsistent. If you must mix, normalize size and stroke in your design system first.
