CSS Filter Generator generates CSS from the controls shown below. Adjust blur, brightness, contrast, saturation, grayscale and hue to preview and copy a CSS filter. Review the output before adding it to your page.
CSS Filter Generator is a free CSS Tools utility that runs entirely in your browser — nothing you enter is uploaded.
How to use CSS Filter Generator
- Adjust Blur (px), Brightness % and Contrast % with the sliders.
- Set Saturate %, Grayscale % and Hue (deg) for the remaining effects.
- Review the sample preview and generated filter declaration.
- Choose Copy and add the declaration to the CSS rule for your image or element.
About this tool
The sliders combine six CSS filter functions and apply them to the built-in sample preview. The result is a CSS declaration; the tool does not upload or export an edited image.
The tool generates CSS locally from your chosen settings. It does not parse or modify a pasted stylesheet. Once the page and its scripts have loaded, generation can run without a network connection.
