Best Practices

  1. Export all sizes upfront: Generate all platform sizes at once
  2. Keep source files: Save your Iconfast project for future edits
  3. Test on devices: Preview icons on actual devices when possible
  4. Consider dark mode: Test visibility on both light and dark backgrounds
  5. Verify transparency: Ensure alpha channel is correct for platforms that support it
