CSS Filter Builder

Build a filter: chain with nine sliders and watch it applied live to a sample image. Drag the divider to compare against the original, then copy the generated CSS.

How the chain works

  • Filters are applied left to right, and each one sees the previous result.
  • Order matters: grayscale(1) blur(4px) and blur(4px) grayscale(1) look different.
  • The tool always writes them in the order listed on the left for predictability.
  • Filters animate smoothly, so they pair well with transitions and hover states.

About this tool

This CSS filter builder assembles a filter: chain from nine functions — blur, brightness, contrast, grayscale, hue-rotate, invert, opacity, saturate and sepia — and applies it live to the image in the preview. Drag the divider across the preview to compare the filtered result against the original, or drop in your own photo to see how a look holds up on real content.

The default sample is an inline SVG gradient landscape, so there is no external asset to download. Uploaded images are read with the FileReader API and rendered straight into the page — they are never uploaded, and nothing about your image leaves the browser.
