About Box Shadow Generator

CSS box shadows add depth, elevation, and visual hierarchy to UI elements — they are a core part of modern web design, used in cards, buttons, modals, navigation bars, and floating action buttons. This tool lets you build box shadows visually with multiple layers, giving you fine-grained control over X and Y offset, blur radius, spread radius, color, and opacity for each layer. Multiple shadow layers can be combined to create realistic, nuanced elevation effects similar to Material Design's elevation system. Toggle inset shadows to create inner glow or pressed-button effects. The live preview updates instantly as you adjust any parameter, so you can experiment with different looks without writing a single line of CSS by hand. When you are satisfied with the result, copy the complete CSS code with one click and paste it into your stylesheet. This is invaluable for frontend developers implementing design systems, prototyping UI components, or recreating shadow effects from a design mockup.

Questions

Is my data sent to a server?

No. All processing happens locally in your browser. No data leaves your device.

What do the shadow values mean?

The box-shadow property takes: horizontal offset, vertical offset, blur radius, spread radius, and color. Blur controls softness, spread controls size, and the offsets control direction.

Can I add multiple shadows?

Yes. You can layer multiple shadows on a single element to create depth effects, glows, or complex shadow compositions. Each shadow is listed comma-separated in the CSS output.

What is an inset shadow?

An inset shadow appears inside the element instead of outside, creating a pressed or recessed effect. Toggle the inset option to switch between inner and outer shadows.

Is my file uploaded to a server?

No. Transmute processes everything locally in your browser using JavaScript and WebAssembly. Your files never leave your device — there is no server, no upload, no cloud processing.
