Design Checklist
Reduce detail early
Small icons fail when the original illustration is too busy. Simplify shapes before export instead of hoping scaling will fix readability.
Test on light and dark surfaces
Favicon and app icon visibility changes with theme context. Check edge contrast before final export.
Export from a clean square source
Use a high-resolution square source asset so the smaller icon sizes are derived from something balanced and centered.
Match format to platform need
ICO is useful for favicon and Windows compatibility. PNG is better when you need sharp transparent assets for mobile and design workflows.
