CSS Filter Generator

The CSS Filter Generator lets you visually build CSS filter effects with a live image preview. Adjust individual filter properties using intuitive sliders and see results instantly — no guesswork needed. Once you’re happy with the look, copy the generated CSS code and paste it directly into your stylesheet.

使い方

Start with the default sample image or upload your own by dragging and dropping an image onto the preview area or clicking “Upload Image”. Then adjust the filter sliders to achieve your desired effect. Each slider controls a different CSS filter property — blur, brightness, contrast, grayscale, hue-rotate, invert, opacity, saturate, and sepia. You can also enable drop shadow with configurable offset, blur, and color. Try one of the built-in presets like Vintage, Dramatic, or Noir for quick starting points. When you’re satisfied, click the Copy button to grab the CSS code.

 よくある質問

What is the CSS filter property and how does it work?

The CSS filter property applies graphical effects like blur or color shifting to an element's rendering. It uses filter functions (blur(), brightness(), contrast(), etc.) that process the element's pixels before displaying them. Multiple filters can be chained together in a single declaration, and they are applied in the order listed.
Do CSS filters affect page performance?

CSS filters are GPU-accelerated in modern browsers, so simple filters like brightness or contrast have minimal performance impact. However, complex filters like blur with large radius values or filters applied to many elements simultaneously can cause frame drops, especially on mobile devices. For best performance, apply filters to as few elements as necessary and avoid animating blur on large areas.
What is the difference between filter and backdrop-filter in CSS?

The filter property applies effects to the element itself and its contents, while backdrop-filter applies effects to the area behind an element. For example, backdrop-filter: blur(10px) creates a frosted glass effect by blurring whatever is visible through the element's background, without affecting the element's own content.
Which browsers support CSS filters?

CSS filters are supported in all modern browsers including Chrome, Firefox, Safari, Edge, and Opera. Safari still requires the -webkit- prefix for some filter functions. Internet Explorer does not support CSS filters at all. For maximum compatibility, include both the -webkit-filter and standard filter declarations in your CSS.
