Glassmorphism Generator Free Online Tool 2026

Last updated March 22, 2026

Glassmorphism Settings Reference

• Blur radius: 8–24px (12px is the sweet spot for most use cases)
• Background opacity: 0.1–0.25 (lower = more transparent glass)
• Border opacity: 0.2–0.4 (subtle white border defines the glass edge)
• Always include -webkit-backdrop-filter for Safari support
• Use @supports for graceful degradation on older browsers
• Avoid heavy use on mobile — backdrop-filter is GPU-intensive
• Check text contrast — frosted glass can reduce readability
