CSS Image Filter Generator
Create custom visual effects for your images using CSS filters. Adjust blur, brightness, contrast, and more, then copy the generated CSS code.
Tip: Copy and paste this into your stylesheet.
About
The CSS Image Filter Generator is a powerful web design tool that allows developers and designers to apply graphical effects to elements, primarily images, directly within the browser. Traditionally, effects like grayscale, blurring, or adjusting brightness required image editing software like Photoshop. With the CSS filter property, these manipulations are rendered dynamically by the browser's graphics engine.
This tool helps you experiment with various filter functions without writing code manually. You can stack multiple effects—such as combining high contrast with a sepia tone—to create unique vintage looks or modern UI states (like dimming an image on hover). Once you achieve the desired look, the tool generates the exact CSS snippet required to implement the effect on your website.
Formulas
The CSS filter property accepts one or more filter functions separated by spaces. The browser processes these functions in the order they are declared.
- Step 1. Define the base selector (e.g.,
imgor.custom-class). - Step 2. Choose filter functions. Example:
grayscale(100%)removes all color. - Step 3. Combine filters if necessary. Example:
brightness(1.2) contrast(1.1). - Final Output.
filter: grayscale(100%) blur(2px);
Note: Some filters like drop-shadow work differently than box-shadow as they respect the alpha mask of the image content rather than the box container.
