Neumorphism Generator

What is Neumorphism?

Neumorphism, or soft UI, is a design style where elements appear to extrude from or press into the background, as if molded from the same material. The effect is achieved with two shadows — a light one and a dark one on opposite sides — over a background of the same color as the element.

Our Neumorphism Generator derives the light and dark shadow colors automatically from your chosen surface color and lets you switch between flat, concave, convex, and pressed styles, with a live preview on a matching background and copyable CSS.

The Four Neumorphic Styles

• Flat — the surface sits level, raised by its outer shadows
• Concave — the surface curves inward with a subtle gradient
• Convex — the surface bulges outward with a reversed gradient
• Pressed — inset shadows make the element appear pushed in

How Neumorphism Works

The key requirement is that the element and its container share the same background color. Two box-shadows are then applied: a darker shade offset one way and a lighter shade offset the opposite way, simulating a single light source. The result is the soft, extruded look.

This tool computes the lighter and darker shades from your base color for you, so the effect always looks natural. Adjust distance, blur, and intensity to make the elevation more subtle or more pronounced.

Using Neumorphism Wisely

Neumorphism looks striking but has an accessibility caveat: because elements share their background color and rely on subtle shadows, contrast can be low, making buttons hard to distinguish for some users. Use it for accents and decorative components rather than critical controls, and ensure interactive elements remain clearly identifiable. The CSS is generated entirely in your browser.

How Paired Shadows Create the Soft-UI Look

Neumorphism is an optical trick built from two box-shadows working together. The element and its container share the exact same background color, so the surface seems to be carved from a single piece of material. One shadow is a shade darker than the background and sits on one side; the other is a shade lighter and sits on the opposite side. Your eye reads this pair as a single consistent light source, which makes the element appear gently raised from — or pressed into — the surface.

The reason the colors must be derived from the base, rather than picked arbitrarily, is that the illusion breaks if the light and dark shades do not relate to the surface. This tool computes those shades for you, lightening and darkening the base color by a calibrated amount so the elevation always looks natural. Switching between flat, concave, convex, and pressed simply changes shadow placement and adds subtle gradients to suggest a curving surface.

Tips for Using Neumorphism

• Keep the element and its container the same background color
• Use it for decorative accents, not critical controls, due to low contrast
• Keep distance and blur moderate so elevation stays believable
• Ensure interactive elements remain clearly identifiable
• Pair it with a clear focus or active state for accessibility

Why Choose Our Neumorphism Generator?

Our neumorphism generator is free with no signup, no limits, and no subscription. It runs entirely in your browser, so the preview and CSS update instantly, work offline, and stay private — nothing is uploaded.

It is one of more than 200 free tools on ToopTools, and you can pin it to your My Workspace, a personalized workspace where you keep the tools you use most in a single dashboard. Beside the box-shadow and button generators, it lets you craft soft-UI surfaces and copy ready-made CSS without leaving your workspace.

Common Use Cases

Neumorphism is used for decorative cards, toggles, music-player controls, and dashboard widgets where a soft, tactile, molded-from-the-surface look fits the brand. It is especially popular in app concept designs and portfolio pieces that want a distinctive, modern aesthetic.

Because the style relies on subtle shadows over a matching background, designers tend to use it selectively — for accent components rather than primary navigation or critical buttons. This tool makes it easy to generate the paired shadows correctly and preview them in context, so you can decide where the effect strengthens your design and where a higher-contrast style serves users better.

Is the Neumorphism Generator free?

Yes. It is completely free with no account, no sign-up, and no usage limits. Generate and copy as many neumorphic styles as you like at no cost.

What is the difference between the four styles?

Flat sits level and is raised by outer shadows. Concave curves inward with a subtle gradient, convex bulges outward with a reversed gradient, and pressed uses inset shadows to look pushed in. They share the same shadow logic with different placement and gradients.

Why does neumorphism need a matching background?

The illusion of a surface molded from one material only works when the element and its container share the same background color. Against a different color, the paired light and dark shadows no longer read as a single, continuous surface.

Is neumorphism accessible?

It has a contrast caveat. Because elements share their background and rely on faint shadows, they can be hard to distinguish for some users. Use it for accents, keep interactive elements clearly identifiable, and add visible focus or active states.

How do I make a pressed or active state?

Switch to the pressed style, which uses inset shadows to make the element look pushed in. Applying that style on click or on the active state gives buttons satisfying, physical-feeling feedback.

Is my design kept private?

Yes. The effect and its CSS are generated entirely in your browser, so nothing is uploaded. The tool is private and works without an internet connection.

How do I create a neumorphism effect in CSS?

Pick a base color and style, then adjust the distance, blur, and intensity — the live preview shows the soft, extruded look. Copy the generated CSS, which includes the matching background and dual shadows, and apply it to your element.

Does the neumorphism generator work offline?

Yes. The effect and its CSS are generated entirely in your browser, so once the page has loaded the tool works without an internet connection, and nothing you design is uploaded. You can build neumorphic styles privately on your own device.
