CSS Filter Generator - Visual Filter Builder

How to use this tool

1. Choose a preview image or starting look. Keep the bundled sample image or choose a local image up to 8 MB. Select a preset such as Vintage or Frosted Glass to load a starting combination.
2. Adjust the effect. Choose filter or backdrop-filter, then refine the sliders and optional drop-shadow controls. Use Original and Filtered to compare the preview.
3. Copy the CSS. Copy the generated declaration and paste it into a stylesheet. Backdrop mode includes the Safari-compatible WebKit declaration.

CSS filter functions

A CSS filter chain applies visual effects to an element in the order they appear. This builder leaves identity values out of the declaration, so unchanged controls produce none and a grayscale-only treatment produces filter: grayscale(100%);. The order of functions can change the result, especially when blur, contrast, and color adjustments are combined.

Browser support

The filter property is supported in current desktop and mobile browsers. The generator emits an unprefixed filter declaration. When you choose backdrop-filter, it also includes -webkit-backdrop-filter for Safari compatibility; older browsers may still ignore effects they do not support.

Usage example

img {
  filter: blur(2px) brightness(110%) contrast(120%);
}

Filters are applied left to right. Order matters: blur(2px) brightness(150%) produces a slightly different result than brightness(150%) blur(2px).

Filter an element or its backdrop

The filter property changes the selected element itself. The backdrop-filter property changes the pixels behind an element, which is useful for frosted panels over photos or page content. Select the output property above the controls to switch the preview and generated declaration together. A backdrop effect needs a transparent or partly transparent background on the element so the filtered pixels can show through.

.modal {
  background: rgba(255, 255, 255, 0.7);
  backdrop-filter: blur(10px);
  -webkit-backdrop-filter: blur(10px);
}

A Gaussian drop-shadow() follows visible pixels in an image, so it can preserve the silhouette of a transparent PNG or icon. box-shadow instead follows the element's rectangular box and supports spread and inset shadows. Use the Box Shadow Generator when you need those box-specific controls, or the Glassmorphism Generator for a fuller translucent-panel recipe.

Performance note

CSS filters are GPU-accelerated in modern browsers, but applying complex filters to many elements simultaneously can create additional compositing layers and strain the GPU. In performance-critical UIs (e.g., infinite scroll, high-frame-rate animation), monitor DevTools' Performance tab to ensure filters aren't causing dropped frames.

Combining filters

You can chain multiple filters in one declaration to create stylistic effects. Example:

img {
  filter: grayscale(50%) contrast(150%) brightness(110%);
}

This partially desaturates the image, boosts contrast, and slightly increases brightness - useful for a faded, vintage aesthetic. Experiment with layering hue-rotate and saturate to create color-grading effects. The preset buttons provide starting combinations, but CSS filters approximate photographic looks rather than reproducing a particular camera or social-media filter exactly.

Preview your own image

The sample landscape is bundled with this page, so it appears without fetching a remote demo image. Choose Use my image to preview a local image up to 8 MB. The browser displays it from a temporary object URL; the tool does not upload it or save it after you leave the page. Choose Clear image to return to the bundled sample.
