What is the best free icon library in 2026?

Lucide is the best overall: 1,500+ icons, consistent design, MIT licensed, tree-shakable for web projects, and available as React/Vue/Svelte components. For a smaller, highly curated set, Heroicons (by Tailwind team) offers 300+ perfectly designed icons in outline and solid. For maximum quantity, Tabler Icons has 5,000+ icons. For brand/social icons, Simple Icons covers 3,000+ brand logos. All are free and commercially usable.

SVG vs icon font: which should I use?

SVG in almost every case. SVGs are sharper at any size, individually styleable with CSS, accessible (can have title/desc), tree-shakable (only load icons you use), and smaller when you use few icons. Icon fonts load the entire set regardless of how many you use, can flash during loading (FOIT), and are harder to style individually. The only case for icon fonts: legacy projects where SVG integration is difficult. For new projects, always use SVGs.

Can I use free icons in commercial projects?

Yes, for most libraries listed here. MIT License (Lucide, Heroicons, Tabler, Feather): use anywhere, modify freely, include in commercial products. No attribution required. ISC/Apache licenses (Phosphor, Ionicons): similar freedom. The key restriction across all: you can't sell the icon set itself as a product. Using icons in your website, app, marketing materials, or client projects is always fine. Check each library's specific license if in doubt.

How many icons does a typical project need?

Most websites use 20-50 unique icons. A typical set: navigation (menu, close, arrow, search, home), actions (edit, delete, copy, download, share, settings), content (image, video, file, folder, link), communication (mail, phone, chat, bell), social (Twitter/X, LinkedIn, GitHub, Instagram), and status (check, warning, info, error). Pick one library and use it consistently throughout the project — mixing icon styles looks unprofessional.
