Free SVG Icon Libraries for UI Designers
16 curated free icons
Last updated: June 2026
Not every icon on the web is safe to drop into a client project. This list focuses on libraries where the license is clear and the default format is SVG — so you can scale icons in Figma, export for the web, and hand off to developers without a font-file workaround. I include sets with optional paid tiers only when the free license covers commercial UI work. If you are building a product interface rather than a one-off landing page, start here before browsing marketplace sites with mixed licensing.

How to pick one
- Check the license first — MIT and Apache are the safest defaults for client SaaS work.
- Pick one stroke weight and corner style per project; mixing libraries is how interfaces start to feel patched together.
- Prefer libraries with official React or Figma packages if your team ships code from the same design file.
Frequently Asked Questions
Can I use these free icons in a commercial SaaS product?
Yes — most libraries here (Lucide, Heroicons, Phosphor, Tabler) use MIT or Apache licenses that allow commercial use. Always verify the license page before shipping client work.
SVG or icon font — which is best for web UI?
SVG is best for web UI. Icons stay sharp at any size, work with CSS, and support accessibility labels. Avoid icon fonts for new design systems.
What are the best free SVG icon libraries in 2026?
Lucide, Heroicons, Phosphor Icons, and Tabler Icons are the top free SVG sets for UI designers — all MIT-licensed, actively maintained, and available as React packages.
Are Lucide icons free for commercial use?
Yes. Lucide uses the ISC/MIT license, which permits free commercial use in products, client sites, and SaaS apps without attribution requirements.
How many free icons do I need for a typical app UI?
Most apps use 30–80 unique icons. Start with one library that covers navigation, actions, and status icons before adding custom glyphs.
