Create frosted-glass effects with CSS
The backdrop-filter property applies graphical effects to the area behind an element, most famously the frosted-glass blur seen in modern operating systems and navigation bars. This generator lets you dial in blur, brightness and saturation, plus a semi-transparent white tint, and outputs the CSS with the webkit prefix for wider support. The result is a translucent panel that blurs whatever sits beneath it.
It is the core technique behind glassmorphism, giving overlays and menus a sophisticated, layered feel.
Where backdrop filters shine
Frosted panels work beautifully for sticky navigation bars over scrolling content, modal overlays, and cards floating above colourful backgrounds. The effect only looks right when there is content behind the element to blur, so it suits overlays rather than solid-background pages. A touch of saturation keeps the blurred colours vivid.
Backdrop filters are supported in modern browsers, with the webkit prefix included for Safari. Keep a readable tint so text on the panel stays legible. All generation happens locally in your browser.
Notes on the generated code
Because the backdrop filter generator runs entirely in your browser, you can experiment with every option and watch the generated code update instantly, with nothing uploaded and no account required. The output is clean, standards-based CSS that works in any project without external libraries or a build step, so you can paste it straight into your stylesheet and refine it further by hand whenever you need to.

It applies effects like blur and brightness to the area behind an element, creating frosted-glass and other see-through effects.
Why include a tint?
A semi-transparent background tint keeps text on the panel readable and strengthens the frosted-glass look over the blurred content.
Where does the effect work best?
On overlays, sticky navbars and cards floating over content or images, where there is something behind the element to blur.
Is it supported everywhere?
It works in modern browsers, and the generated CSS includes the webkit prefix for Safari. Provide a fallback background for older browsers.
