CSS Filter Generator

CSS filter supports: blur(), brightness(), contrast(), grayscale(), hue-rotate(), invert(), opacity(), saturate(), sepia(), and drop-shadow(). You can chain multiple filters in a single declaration. Tip: the order matters — filters are applied left to right, so blur() before brightness() gives a different result than the reverse.

filter applies effects to the element itself and its contents. backdrop-filter applies effects to everything behind the element, creating frosted-glass or blur-behind effects. Tip: use backdrop-filter for navigation bars, modals, or overlays where you want the background to blur.

Filters are GPU-accelerated in modern browsers, so simple filters like brightness and contrast are fast. However, blur() with large radius values can be expensive, especially on large elements or when animated. Tip: limit blur radius to 20px or less for smooth performance, and avoid applying filters to elements that cover the full viewport.

Apply filter: brightness(0.85) contrast(1.1) to images in dark mode. This slightly dims images and increases contrast so they look natural against dark backgrounds. For a dramatic effect, add grayscale(0.1) or sepia(0.05) to warm the image.

Yes, all filter functions are animatable. You can transition filter values on hover, focus, or via @keyframes. Example: transition: filter 0.3s ease; then change filter on :hover. Tip: animate a single property at a time (e.g. just brightness) for the smoothest performance.
