Glassmorphism Generator
Build a frosted-glass CSS panel visually — tint, blur and border, with a live preview.
Calculated locally in your browser.
- Adjust tint color, tint opacity, blur strength, border opacity and corner radius independently.
- Live preview against a vivid gradient background — glassmorphism only reads correctly with something behind it to blur.
- Outputs both the standard `backdrop-filter` and the `-webkit-` prefixed version Safari still needs.
Why this is private
- Calculated locally in your browser.
- Open your browser's DevTools → Network tab while using this tool — you won't see a request carrying your input, because it never leaves your device.
- Nothing you enter is uploaded to a server or shared with us — the processing happens entirely on your device.
Overview
Builds the CSS for a frosted-glass ('glassmorphism') panel — a semi-transparent tinted background, a backdrop blur, and a light border — with a live preview against a colorful backdrop so you can see the blur actually working, not just read four property values.
How to use it
- 1Pick a tint color and opacity for the glass panel.
- 2Set the backdrop blur strength.
- 3Adjust border opacity and corner radius to taste.
- 4Copy the CSS onto an element positioned over some background content or image.
Tips
- Backdrop blur only has something to blur if there's actual content — an image, gradient, or other elements — positioned behind the panel. Placed over a flat solid background, it will look identical to a plain semi-transparent panel.
