How to use the glassmorphism generator

  1. Adjust blur, background opacity, color, border opacity, and radius.
  2. Watch the live preview update.
  3. Copy the generated CSS.

How this works

Everything runs entirely in your browser — the preview uses the same CSS (background, backdrop-filter, border) that's generated for you to copy.

Common use cases

  • Design a frosted-glass card or panel effect for a website
  • Get ready-to-use backdrop-filter CSS for a design
  • Experiment with blur, opacity, and border settings visually

Frequently asked questions

Is this glassmorphism generator free?

Yes. It is completely free, with no signup and no limits.

Does backdrop-filter work in every browser?

It's supported in all current major browsers (Chrome, Edge, Safari, Firefox), though older browser versions may not render the blur effect.

Can I use this with any background?

Yes — the frosted-glass effect works best over a colorful or image background, which is why the preview uses a gradient backdrop.
