Glassmorphism & Neumorphism Generator
Generate frosted-glass and soft-UI CSS effects.
Design trendy glassmorphism (frosted, semi-transparent backdrop-blur) and neumorphism (soft, extruded same-colour UI) effects with live sliders for blur, transparency, colour, depth and shape. Preview over a real backdrop, then copy ready-to-paste CSS with the -webkit- prefix included. Runs fully in your browser — nothing is uploaded.
How to use Glassmorphism & Neumorphism Generator
Choose a style
Use the toggle in this free online glassmorphism and neumorphism generator to pick the frosted-glass look or the soft UI extruded surface you want to design.
Set a backdrop
In glassmorphism mode, pick a vivid backdrop preset so the backdrop-filter blur and transparency are actually visible behind your frosted glass card.
Tune glass sliders
Drag the blur, transparency, saturation and border-radius sliders and set a tint colour to craft the exact semi-transparent frosted glass effect you need.
Shape neumorphism
Switch to neumorphism, choose a flat, concave, convex or pressed shape, and adjust distance, blur, intensity and the surface colour for a soft extruded look.
Preview live
Watch the live preview update instantly as you tweak values, showing a faithful one-to-one of the CSS so what you see is exactly what you copy.
Copy the CSS
Click Copy to grab the clean, ready-to-paste CSS, including the -webkit- prefix for Safari, and drop it straight into your stylesheet or component.
Frequently asked questions
What is glassmorphism?
Glassmorphism is the frosted-glass UI style: a semi-transparent panel that blurs whatever sits behind it, finished with a soft shadow and a thin highlight border. It is built from an rgba() background plus a backdrop-filter blur, and it only looks like glass when there is a colourful image or gradient behind the element to blur.
What is neumorphism?
Neumorphism (or 'soft UI') makes an element look gently extruded from — or pressed into — the page. The trick is that the element is the same colour as its background, and the depth comes entirely from a pair of shadows: a dark one on the side away from the light and a light one toward it. Inset shadows on both sides create the pressed-in variant.
Why does backdrop-filter need a background?
backdrop-filter blurs the pixels behind an element. If the parent is a flat solid colour, blurring it changes nothing, so the glass effect is invisible. Place the card over a photo or a vivid gradient — like the backdrop presets in this tool — and the frosted look appears.
Which browsers support this, and why the -webkit- prefix?
backdrop-filter works in current Chrome, Edge, Firefox and Safari. Safari (and older iOS) still requires the -webkit-backdrop-filter prefix, so this tool always emits both lines. Neumorphism uses only box-shadow and border-radius, which every modern browser supports.
Is neumorphism accessible?
Use it carefully. Because the surface and its background share one colour, neumorphic controls have very low contrast and the soft shadows can be hard to perceive — especially for low-vision users. Don't rely on shadow alone to signal that something is a button: add clear labels, focus states and sufficient text contrast (WCAG AA).
Is anything I design uploaded?
No. The CSS is generated entirely in your browser with plain string and number maths. Nothing you build is sent to or stored on a server.
