About

This tool runs entirely in your browser using plain JavaScript — your designs never leave your device. You can stack multiple shadow layers to create depth effects, neumorphism, glow effects, or subtle card elevations. Each layer supports inset shadows for inner-glow or pressed-button looks. The output is standard CSS you can drop straight into any stylesheet, framework, or design token.

How to use

  1. Click '+ Add Shadow' to create your first shadow layer.
  2. Use the Offset X, Offset Y, Blur, Spread, and Opacity sliders to shape each shadow. Toggle 'Inset' for an inner-shadow effect.
  3. Click the color swatch to pick any shadow color. The live preview updates as you adjust every control.
  4. Add more layers for complex multi-shadow effects like neumorphism or stacked glows.
  5. Click 'Copy CSS' to grab the complete box-shadow declaration and paste it into your stylesheet.

FAQ

Is this CSS box-shadow generator free?
Yes, completely free. No account, no trial period, no hidden cost — just open the page and start generating shadows.
Does it work offline, without an internet connection?
Yes. The tool runs entirely in your browser with no server calls. Once the page loads, you can disconnect from the internet and it will continue to work perfectly.
Is my design data private? Does anything get uploaded?
Nothing is uploaded. All shadow settings are processed locally in your browser and saved only to your browser's localStorage. No data ever leaves your device.
Can I layer multiple shadows in one CSS rule?
Yes. Click '+ Add Shadow' as many times as you need. The tool stacks all layers into a single comma-separated box-shadow value — perfect for neumorphism, glow effects, or multi-directional depth.
How do I create an inset (inner) shadow effect?
Check the 'Inset' checkbox on any shadow layer. An inset shadow appears inside the element boundary, useful for pressed-button states or inner-glow effects. The generated CSS includes the 'inset' keyword automatically.
