Icons seem like small design elements, but they can quietly shape a brand’s usability, personality, and overall sense of polish. The right icon system can make a website feel intuitive, a product feel modern, and a brand feel cohesive. The wrong icons? They create visual noise, mixed metaphors, and that dreaded “template” look that instantly cheapens a design.
Most early-stage brands don’t have the budget for a fully custom icon library, so I often rely on high-quality free icon sets as a starting point, but only when curated and used intentionally. My goal is always to build a consistent visual system, not to randomly mix and match styles.
Below is my personal, working list of the best free icon libraries for commercial use and how I use each one within real design explorations.
How To Use Free Icons in Brand & Digital Design
Before the list, here’s my core approach:
- Choose icons based on brand personality, not convenience.
Rounded for friendly brands, sharp for tech-forward brands, ultra-simple for modern minimalism, etc. - NEVER mix icon styles unless intentionally creating a mixed-style system.
Line thickness, corner radius, and proportions have to match. - Treat icons as part of the brand’s codification system.
They’re not decorative, they’re structural elements of the brand’s visual language. - Verify licenses carefully.
Some “free” icon sets require attribution or have restrictions on certain types of commercial work.
Top Free Stock Iconography Resources for Creatives
1. Feather Icons
A lightweight, beautifully minimal icon set with open-source licensing. I use Feather when I want a polished, modern UI aesthetic. Perfect for SaaS dashboards, onboarding flows, or clean brand systems.
2. Heroicons (by Tailwind Labs)
A fantastic collection of outline and solid icons designed for modern interfaces. I use Heroicons in web products and apps that need friendly yet professional visuals.
3. Phosphor Icons
One of my go-to multipurpose icon packs. Tons of styles, thin, bold, duotone, filled, so I can adapt the system to match the brand’s personality without hunting across multiple libraries.
4. Lucide Icons
The spiritual successor to Feather Icons with a wider selection. Lucide is my favorite for brands that want that crisp, minimal stroke look without feeling too sterile.
5. Iconoir
A large, well-designed open-source library with a slightly more expressive style. I use Iconoir for lifestyle, creative, wellness, and culture-forward brands that want something less generic.
6. Remix Icon
A clean, versatile set with consistent proportions and a great mix of solid + line icons. Ideal for site navigation, product features, and marketing pages.
7. Material Icons (Google)
The classic. I use these mainly for apps or websites that need recognizable, universal UI patterns, or when accessibility requires the most familiar icon metaphors.
8. Font Awesome Free
Still relevant for quick prototypes or early wireframes. Not my first choice for final brand systems, but essential for fast iteration and familiarity.
9. Bootstrap Icons
A straightforward, highly consistent set perfect for corporate, financial, government, or enterprise-adjacent brands needing clarity over personality.
10. Tabler Icons
Extremely well-crafted and great for data-heavy dashboards or fintech. Their consistent stroke system makes them ideal for B2B SaaS brands.

A stylish dual-tone icon pack with both filled and outline versions. I use these for brands that need a slightly more expressive, personality-driven interface.
12. Icons8 (Free Tier)
A large collection of styles, including line, glyph, and colored icons. Best for early mockups, moodboards, or exploratory brand direction, just double-check attribution requirements.
13. The Noun Project (Free Tier)
Massive library contributed by global designers. I use Noun Project when I need hyper-specific icons, but always with attribution or a paid license.
14. Flaticon (Free Tier)
Great for niche categories and exploratory design work. As long as attribution is okay, it’s one of the biggest icon resource platforms available.
15. Iconscout (Free Plan)
Another great source for diverse styles. Not always perfect for unified branding, but helpful when you need options fast.
16. SVG Repo
An open database of SVGs free for commercial use. Perfect for custom modification, remixing, and building unique icon sets when existing libraries fall short.
17. OpenMoji (CC BY-SA)
Bright, friendly, expressive emoji-style icons. I use this for playful brands or youth-oriented products.
