The free Glassmorphism CSS generator for frosted-glass UI

This glassmorphism CSS generator lets you design that modern frosted-glass effect — the translucent, blurred “glass” panels you see in iOS, macOS Big Sur, Windows 11 and countless dashboards — and export clean, copy-paste CSS, Tailwind or HTML in seconds. Adjust the blur, transparency, saturation, tint, border and shadow, watch the live preview update instantly, then ship the generated backdrop-filter code straight to your project. No sign-up, no watermark, completely free.

What is glassmorphism?

Glassmorphism is a UI design trend built around frosted, semi-transparent surfaces that blur whatever sits behind them. The effect is created in CSS with the backdrop-filter: blur() property, a translucent rgba() background, a subtle light border and a soft drop shadow — together they sell the illusion of layered frosted glass and give an interface real depth.

How to create a glassmorphism effect with CSS

  1. Pick a background — glass only reads as glass over something colourful, so choose one of the gradient or photo backdrops.
  2. Set the blur — backdrop-filter: blur() is the heart of the effect. 8–20px works for most cards.
  3. Tune transparency & tint — lower the background opacity for more “see-through” glass and add a colour tint if you want it warm or cool.
  4. Add a border & highlight — a 1px semi-transparent white border plus an inner top highlight catches the light like a real glass edge.
  5. Layer a shadow — a soft drop shadow lifts the panel off the page.
  6. Copy the code — grab the CSS, Tailwind or HTML and paste it into your project.

Features of this glassmorphism generator

  • Live preview — drag the glass card anywhere over real gradients and photos.
  • Full control — blur, transparency, saturation, brightness, tint, radius, size, border, highlight, shadow and noise.
  • Readability meter — a built-in WCAG contrast check so your text stays legible on the glass.
  • One-click presets — Frosted, Subtle, Heavy, Dark, Aqua and more.
  • Cross-browser CSS — includes the -webkit-backdrop-filter prefix for Safari and iOS.
  • Export anywhere — copy as CSS, Tailwind utility classes or ready-made HTML.

Browser support for backdrop-filter

The glassmorphism effect is supported in all modern browsers — Chrome, Edge, Firefox and Safari. Safari and older iOS versions need the -webkit-backdrop-filter prefix, which this generator always includes in the exported code. For unsupported browsers, the semi-transparent background still provides a graceful fallback.

Glassmorphism CSS — frequently asked questions

Is this glassmorphism generator free to use?

Yes. The generator is 100% free with no sign-up, no watermark and no limits. Design your frosted-glass component and copy the CSS as many times as you like.

What CSS property creates the frosted-glass blur?

The blur comes from backdrop-filter: blur(10px) (with the -webkit- prefix for Safari), combined with a translucent rgba() background, a light border and a soft shadow. This tool generates all of those properties for you.

Does glassmorphism work in Safari and on iOS?

Yes, as long as you include the -webkit-backdrop-filter prefix, which the exported code does automatically. The effect works across Chrome, Edge, Firefox and Safari.

How do I keep text readable on a glass card?

Watch the built-in readability meter. If contrast is low, reduce the transparency (raise the background opacity), increase the blur, or switch the text colour. Aim for a WCAG AA contrast ratio of at least 4.5:1 for body text.

Can I use the generated CSS with Tailwind?

Absolutely. Switch the output tab to Tailwind and you’ll get utility classes using arbitrary values such as backdrop-blur-[10px] and bg-white/25 that you can drop straight into your markup.
