Glassmorphism Generator

Glassmorphism is a UI design trend that creates a frosted glass look using background blur and semi-transparency. It relies on the CSS backdrop-filter property to blur whatever sits behind a translucent element, producing a sense of depth and layering that works particularly well over colourful backgrounds or images.

backdrop-filter is supported in all modern browsers: Chrome 76+, Firefox 103+, Safari 9+ (with -webkit- prefix), Edge 79+, and Opera 63+. Internet Explorer has no support. This generator outputs both the prefixed and standard properties automatically.

Yes. Tailwind includes backdrop-blur utilities like backdrop-blur-md and background opacity modifiers like bg-white/20. This generator outputs the closest matching Tailwind utility classes for your settings.

Glassmorphism looks best over colourful or high-contrast backgrounds such as gradients, vibrant images, or overlapping shapes. The blur effect needs visible content behind it to create the frosted glass illusion. A plain white background will not produce a noticeable glass effect.

backdrop-filter blur is GPU-accelerated in modern browsers and generally performs well. However, using very large blur values (above 30-40px) on many overlapping elements can impact frame rate on lower-end devices. For most designs, a blur between 8-20px provides a good balance of visual effect and performance.

The opacity slider controls the transparency of the glass card background itself (how much colour is visible in the fill). The border opacity slider controls how visible the card edge is. A lower background opacity with a slightly higher border opacity creates a subtle outlined glass look.
