What is CSS backdrop-filter?

CSS backdrop-filter applies graphical effects like blur, brightness, contrast, and more to the area behind an element. It is commonly used to create the popular frosted glass UI effect — a translucent element that subtly blurs the content beneath it.

What filters can I generate with this tool?

This tool lets you control: blur (px), brightness (%), contrast (%), grayscale (%), hue-rotate (deg), invert (%), opacity (%), saturate (%), and sepia (%). You can combine multiple filters and see the result live.

Is backdrop-filter supported in all browsers?

backdrop-filter is supported in all modern browsers including Chrome, Firefox, Safari, and Edge. Safari requires the -webkit-backdrop-filter prefix, which this generator includes automatically in the CSS output.

How do I use the generated CSS?

Click 'Copy CSS' and paste it into your stylesheet. Apply the class or property to the HTML element you want to affect. Make sure the element has a semi-transparent background (e.g. background: rgba(255,255,255,0.15)) for the backdrop blur to be visible.

Can I create a frosted glass effect?

Yes! Click the 'Frosted Glass' preset to get a classic frosted effect quickly. It sets a moderate blur with slight brightness and contrast adjustments for a realistic glass appearance.
