Glassmorphism mimics frosted glass by combining a semi-transparent background with `backdrop-filter: blur()` (plus optional saturate/brightness) so content behind the panel softens.
This generator previews the effect on customizable gradient or photo backgrounds, stacks up to three glass layers, checks WCAG contrast on preview text, and exports CSS, SCSS, CSS variables, Tailwind, design tokens, HTML, and React components—including `-webkit-backdrop-filter` for Safari and `@supports` fallbacks.
All tuning runs in your browser; share designs via URL query parameters.
Concise answers for common searches — definitions, steps, and comparisons.
Builds frosted-glass CSS with backdrop-filter blur, translucent fills, borders, and shadows—live preview and copy-ready CSS, Tailwind, and React exports.
Yes. All tuning and export run in your browser—designs are not uploaded unless you share a URL yourself.
Use -webkit-backdrop-filter alongside backdrop-filter. This tool exports both plus @supports fallbacks.
Choose a gradient library scene or upload a photo, then apply VisionOS, Material, Fluent, or iOS presets.
Adjust blur (0–40px), fill opacity, saturation, brightness, noise, border, shadow, and radius. Add up to three layers.
Review the WCAG contrast score on preview text—aim for 4.5:1 for body copy on the composited glass.
Copy CSS, Tailwind, SCSS, variables, tokens, HTML, or React. Share the URL to restore your design.
Common real-world scenarios where this tool saves time.
Export a glass nav bar CSS block for landing pages—pair with the CSS Gradient Generator for hero backgrounds.
Use the modal template to preview frosted dialogs over dimmed content before copying HTML.
Export JSON design tokens for `--glass-*` variables consumed by component libraries.
Estimate contrast before shipping glass cards—then validate in the Color Contrast Checker.

`.glass` class with backdrop-filter stack and fallback tintModerate blur keeps UI readable while showing depth on photographic heroes.
Input

High blur (24px), bright border, soft shadowMatches Apple-style vibrancy—verify contrast if text sits directly on glass.
Translucent fill → backdrop-filter blur/saturate/brightness → border → box-shadow → optional SVG noise overlay.
Pick the right frosted or soft-shadow style.
| Aspect | Glassmorphism | Neumorphism |
|---|---|---|
| Core effect | Backdrop blur + transparency | Dual box-shadow extrusion |
| Best background | Gradients and photos | Flat, similar-tone surface |
| Typical use | Nav, modals, overlays | Buttons, cards, toggles |
| EverydayTools tool | This generator | Neumorphism Generator |
Controls available in this generator.
| Property | Range | Notes |
|---|---|---|
| blur() | 0–40px | Primary frosted effect |
| saturate() | 50–200% | VisionOS-style vibrancy |
| brightness() | 70–130% | Lift or dim background bleed |
| Fill opacity | 0–95% | Light or dark tint base |
| Related tool | Use this tool when | Use related tool when |
|---|---|---|
| Neumorphism Generator | You need frosted overlays, nav bars, or modal glass on colorful backgrounds. | You want soft extruded buttons and cards on flat surfaces using box-shadow. |
| CSS Gradient Generator | You have a hero gradient and need the glass panel CSS on top. | You only need the background gradient without blur. |
| Color Contrast Checker | Quick contrast estimate while tuning glass fill opacity. | Final audit with exact foreground and background hex values. |
VisionOS, Material, and Fluent presets encode realistic blur/saturation ratios.
Older browsers receive an opaque tint—included in full CSS export.
Build the hero in CSS Gradient Generator, then glass overlay here.
Use gradients or photography—blur is invisible without visual detail behind the panel.
This tool exports both standard and WebKit prefixed properties for Safari.
Watch the WCAG analyzer—add a scrim, darken text, or increase fill opacity.
Each panel promotes a GPU layer—limit depth on low-end devices.
Likely cause: Flat background or zero blur radius.
Fix: Increase blur to 12px+ and pick a colorful gradient or upload an image.
Likely cause: Missing -webkit-backdrop-filter in hand-written CSS.
Fix: Copy export from this tool—both prefixes are included.
Likely cause: Truncated URL or edited query string.
Fix: Copy the full URL after the `?g=` parameter stabilizes (~500ms after edits).
Blur reduces legibility—use solid surfaces or neumorphism for tactile controls.
Backdrop filters do not print—use flat colors for PDF output.
GPU cost rises with stacked filters—prefer one hero glass layer.
Continue the workflow with the right follow-up tool.
Yes for Safari and older WebKit browsers. Every export includes both `backdrop-filter` and `-webkit-backdrop-filter`.
0–40px blur, plus saturation (50–200%) and brightness (70–130%) on the backdrop-filter stack.
It estimates contrast between your preview text color and the composited glass-over-background color—not a pixel scan. Validate final designs in the Color Contrast Checker.
Yes—click Share URL. Settings serialize into the `?g=` query parameter. Custom uploaded background images are not embedded; pick a library gradient for portable links.
CSS with @supports fallback, SCSS, CSS custom properties, Tailwind @layer snippet, JSON design tokens, standalone HTML, React component, and inline styles.
Up to three layers—each exports as `.glass`, `.glass-2`, `.glass-3` with independent settings.
No—all processing is local. Share links encode settings in the URL; optional presets save to localStorage on your device.
Glassmorphism uses transparency and backdrop blur; neumorphism uses dual box-shadows on similar-tone backgrounds. Use glass for overlays, neumorphism for tactile buttons.
Glass settings are processed in your browser. Nothing is uploaded to EverydayTools servers unless you choose to share a URL.
Exports mirror preview inline styles including WebKit prefixes and optional noise pseudo-elements.
Pipeline: rgba fill → backdrop-filter stack → border → box-shadow → optional ::before noise tile.
Test Safari and Chrome side-by-side; confirm fallback block activates when disabling backdrop-filter in DevTools.
Limitations: Uploaded background images are not embedded in share URLs. Contrast score is heuristic. Animated PNG backgrounds export as static scenes.
For UI prototyping—not a substitute for platform-native vibrancy APIs on iOS/macOS.
