Licensing Quick Reference

FAQ

Q: Can I use these for client work?

Check each license, but most listed here allow commercial use including client work. Noun Project (free tier) and Storyset require attribution.

Q: How do I customize colors in SVG icons?

Open the SVG in a text editor—look for fill or stroke attributes and change the hex color. Or use Figma/Illustrator for visual editing.

Q: These all look the same. How do I stand out?

Combine elements: icon + gradient background + subtle pattern. Or use less common sources like Blush or DrawKit. Customizing colors to your brand also helps.

Q: What resolution should I export?

For blog covers: 1200x630px minimum. For social: check each platform's requirements. Always export at 2x if you have retina displays to consider.

Q: Icons or illustrations—which should I use?

Icons for technical, minimal, or professional content. Illustrations for friendly, conceptual, or narrative content. When in doubt, test both with your audience.
