Get to know this tool

CSS Glassmorphism Generator lets you design the popular "frosted glass" UI effect visually and grab the matching CSS instantly. Adjust blur, transparency, and color, and the preview and code update together in real time — nothing is ever uploaded anywhere.

What is CSS Glassmorphism Generator and Why is it Useful?

CSS Glassmorphism Generator is a free browser tool for building the frosted-glass look — translucent panels with a blurred backdrop, a soft border, and a subtle shadow — without hand-tuning rgba() values and backdrop-filter syntax. It is useful for front-end developers and designers who want a quick, accurate glass-panel style for cards, modals, navbars, or hero sections.

Key Features

  • Live Blur Control: Adjust the backdrop blur radius from 0 to 30px with a slider and see the frosted effect change instantly.
  • Adjustable Transparency: Set the panel's background opacity from fully transparent to fully opaque.
  • Custom Tint Color: Pick any background color to tint the glass panel.
  • Live Preview That Matches the Code: The preview box and the copyable CSS code are generated from the exact same style values, so what you see is always what you get.
  • Safari-Compatible Output: The generated code includes both the standard backdrop-filter property and the -webkit-backdrop-filter prefix required by Safari, so the effect renders consistently across browsers.
  • Fully Client-Side: All color and blur calculations run locally in your browser. No style data is ever sent to a server.

How to Use This Tool?

  1. Drag the Blur Radius slider to set how strongly the background behind the panel is blurred (0–30px).
  2. Drag the Opacity slider to control how transparent or solid the glass panel looks.
  3. Pick a Color to tint the glass panel.
  4. Watch the preview box update instantly as you adjust blur, opacity, or color.
  5. Copy the generated CSS from the code box — it includes background, backdrop-filter (with the -webkit- prefix), border, border-radius, and box-shadow.

Why Choose Our Client-Side Tool?

Getting glassmorphism right by hand means juggling rgba() alpha values, blur units, and browser prefixes. This tool handles all of that for you while running fully offline once loaded, with zero network requests and zero data collection.

Frequently Asked Questions (FAQ)

Why does the generated CSS include -webkit-backdrop-filter?

Safari requires the -webkit- prefix to apply backdrop-filter. The generator always outputs both properties together so the glass effect works correctly in Safari as well as Chrome, Firefox, and Edge.

Is the preview guaranteed to match the copied CSS code?

Yes. The preview box and the CSS code box are both generated from the same style values, so the blur, transparency, and color you see in the preview are exactly what gets copied.

What happens if I set blur to 0 or opacity to 100%?

Setting blur to 0 removes the backdrop blur, leaving a flat translucent panel. Setting opacity to 100% makes the panel fully solid, removing the see-through glass look. Both are valid CSS values handled correctly by the tool.

Is my style data sent anywhere?

No. All colors, blur, and opacity values stay in your browser. Nothing is uploaded or stored.
