Free CSS Box Shadow Generator — build beautiful shadows visually.

Getting box-shadow right by hand is tedious — guessing pixel values, pasting into a stylesheet, and reloading to check. This free CSS box shadow generator lets you build single or multi-layer shadows visually, with a live preview that updates as you drag. Adjust offset, blur, spread, color, and opacity for each layer independently.

When you're done, copy the shadow in any format — plain CSS, a CSS custom property, SCSS variable, React inline style, or a Tailwind config snippet. No sign-up, no watermarks, completely free.

What you get

Multi-layer shadow editor

Stack as many shadow layers as you need. Toggle visibility or delete individual layers without losing your work on others.

Live preview shapes

See your shadow on a square, rounded box, circle, card, or button shape against light, white, dark, or gradient backgrounds.

5 export formats

CSS property, CSS custom property (:root variable), SCSS variable, React inline style, and Tailwind config block.

Inset shadow support

Toggle inset per layer to create pressed button states, inner glows, and recessed surface effects.

drop-shadow() equivalent

Instantly see the CSS filter version for SVGs and PNGs with automatic warnings when inset or spread values are excluded.

12 designer presets

Soft lift, neumorphic, glow effects, layered depth, flat neon, and more — apply in one click and customise from there.
