CSS Filter Generator

The CSS Filter Generator is a visual editor for the CSS filter property. You move a slider for each filter function - blur, brightness, contrast, saturate, grayscale, sepia, invert, hue-rotate, and opacity - and watch the effect apply to a preview in real time, then copy the exact CSS it produces.

The filter property applies graphical effects like blurring, colour shifting, and contrast adjustment directly in the browser, with no image editor required. Multiple functions can be chained in a single declaration and are applied in order, which is how photo-style looks such as vintage, warm, and dramatic are built. This tool manages that chain for you and outputs only the functions you changed, keeping the CSS clean.

Everything happens in your browser. The page opens on the Vintage preset; pick another preset, fine-tune each function, and copy the declaration. No account, no uploads, and it keeps working offline once the page has loaded.

Here is the CSS filter generator on a warm photo look. Click the Warm preset and Generated CSS reads filter: brightness(105%) saturate(140%) sepia(25%); with the preview shifting toward amber. Drag Blur to 2px and the line becomes filter: blur(2px) brightness(105%) saturate(140%) sepia(25%);. Click None, or press Reset, and it returns to filter: none;. Because the preview is a fixed colour sample rather than your own photo, check the copied CSS on the real image before you ship it.

Filters apply in the order written, and the order changes the result: grayscale then sepia is not the same as sepia then grayscale, because the first removes the colour the second would tint. The gotcha worth knowing is structural rather than visual. Any element with a filter other than none becomes a containing block for its fixed and absolutely positioned descendants, so a dropdown or modal inside a filtered parent will position itself against that parent instead of the viewport. It also creates a new stacking context, which can break z-index ordering that worked before. If a filter breaks a layout in a way that looks unrelated to appearance, that is almost always why. Filters are GPU-accelerated in most browsers, but large blur radii on large elements remain expensive. This tool always writes the functions in one fixed order, blur first and opacity last, so it cannot produce sepia before grayscale; reorder the functions by hand after copying if you need that.
