About This Tool
CSS Filter Generator controls blur, brightness, contrast, grayscale, hue rotation, inversion, opacity, saturation, and sepia. The preview uses built-in visual elements and never requests remote images.
How to Use
- Move the sliders or enter values to adjust the filters.
- Watch colors, edges, and opacity change in the live preview.
- Copy the generated filter declaration.
- Click Reset to restore all defaults, producing filter: none.
Examples
- grayscale(100%) produces a fully grayscale appearance.
- brightness(120%) increases brightness; brightness(100%) preserves the original level.
- blur(2px) softens edges, while opacity(50%) makes the element semitransparent.
filter: blur(2px) brightness(120%) contrast(110%) saturate(130%);
filter: none;How It Works & CSS Details
CSS filter applies visual effects to the rendered element in declaration order. Defaults are blur 0px, brightness 100%, contrast 100%, grayscale 0%, hue-rotate 0deg, invert 0%, opacity 100%, saturate 100%, and sepia 0%. Default functions can be omitted; if all values are at their defaults, the output is none.
Common Uses
- Compare filter styles for cards, illustrations, and images.
- Prepare CSS for hover states and theme effects.
- Understand how combining filter functions changes the appearance.

FAQ
What is CSS filter?
It is a browser visual-effect property that applies effects such as blur, brightness, color changes, and opacity to an element.
What does brightness(100%) mean?
It preserves the original brightness. Values below 100% darken the element; values above 100% brighten it.
How do blur() and opacity() work?
blur() uses a nonnegative length to control blurring. opacity() uses 0–100% to control opacity, with 100% fully opaque.
Does CSS filter change the original image?
No. It changes only the browser's display and does not write to or modify the source image file.
Why does Reset output filter: none?
When all settings return to their neutral defaults, none fully describes the result without listing each default function.
