CSS Filter Generator

About This Tool

The CSS Filter Generator lets you visually adjust nine CSS filter functions — blur, brightness, contrast, grayscale, hue-rotate, invert, opacity, saturate, and sepia — and see the combined effect on a preview element in real time. Filters at their default value are automatically excluded from the output.

CSS filters apply visual effects to elements similar to photo editing software. They are GPU-accelerated and work on images, backgrounds, text, and any HTML element. All processing happens in your browser.

How to Use

1. Drag any slider to apply that filter effect.
2. Combine multiple filters — the preview updates live.
3. Filters at default values are excluded from the output automatically.
4. Click Reset all to return to defaults.
5. Click Copy to copy the CSS filter property.

Use Cases

Designers use grayscale and sepia on images for monochrome UI sections. Developers use blur for frosted-glass backgrounds. Hover effects commonly use brightness to lighten images. Dark mode implementations use invert filters for images that adapt to the theme.

FAQ

• What is the difference between filter and backdrop-filter? — filter applies to the element itself and all its children. backdrop-filter applies only to the area behind the element (useful for frosted-glass overlays).
• Can I combine multiple filters? — Yes. List them space-separated in the filter property. This tool does that automatically.
• Do CSS filters affect performance? — Simple filters like grayscale and brightness are cheap. Blur is more expensive, especially on large areas — use it sparingly on mobile.
