What does this tool do?
The CSS Filter Generator lets you dial in visual effects like blur, brightness, contrast, grayscale, hue-rotate, invert, opacity, saturate, and sepia with sliders while watching a live preview. Start fast with built-in Grayscale, Sepia, Invert, Warm, and Cool presets, then copy the generated filter: value in one click. It's handy for designers who want to style images and elements without any JavaScript.
How to use it
- Adjust the values and options.

Combining the nine filters
Each slider maps to a CSS filter function, and the values are chained in order, for example filter: blur(2px) brightness(110%) saturate(150%). The tool cleverly outputs only values that differ from the default, so leaving contrast at 100% keeps it out of the code and the result stays clean. Brightness and contrast range 0-200%, saturate goes up to 300%, and hue-rotate spans 0-360 degrees.
Presets and real-world uses
The Warm preset adds sepia and saturation for a cozy photo tone, while Cool uses hue-rotate for a chilly blue look. Grayscale and Sepia are common for hover effects in product galleries. invert(100%) can flip images as a dark-mode trick, and blur gives a soft backdrop for modals or loading states. The preview gradient reflects every change instantly so you can fine-tune the exact look.
Frequently asked questions
Why don't some filters appear in the output?
The tool only writes sliders that differ from their default: brightness, contrast, opacity, and saturate are hidden at 100%, and the rest at zero. This keeps the filter value short and readable. If no filter is active, the output is filter: none.
Can I apply these filters to a background?
The filter property applies to the whole element. To blur only the area behind an element while keeping its content sharp, use the backdrop-filter property in CSS with the same value instead.
