CSS Backdrop Filter Generator

How to use

1. 1Pick a preset to start from a known good combination, or leave the defaults and tune from there.
2. 2Drag the function sliders (Blur, Brightness, Contrast, Grayscale, Hue rotate, Invert, Opacity, Saturate, Sepia) to shape how the area behind the surface is filtered. Disabled functions are not included in the output.
3. 3Optionally enable Drop shadow and set its X and Y offsets, blur, color, and opacity to add a glow that bleeds onto the backdrop.
4. 4Switch the preview between Card, Pill, Nav bar, and Modal shapes and between Photo, Gradient, Neon, Dark, and Light backdrops to confirm the surface reads in real contexts.
5. 5Adjust the surface tint slider to match the translucent fill you plan to pair the backdrop-filter with in production. The tint is preview-only and is never included in the copied output.
6. 6Copy the CSS block (which includes the -webkit-backdrop-filter fallback for Safari), the React style object, or the Tailwind v3+ arbitrary-value class and paste it into your project.

About this tool

CSS Backdrop Filter Generator builds the value for the CSS backdrop-filter property, the modern way to blur, tint, or recolor the area behind a translucent element so headers, sticky navigation bars, modal scrims, and hero cards over photos read as crisp glass. The property accepts the same function set as the regular CSS filter property, but it targets what is behind the element instead of the element itself, which is what makes it the foundation of frosted glass, iOS-style materials, and the layered translucency that ships in modern macOS and Windows. Every function is exposed in this tool: blur in pixels, brightness, contrast, grayscale, hue-rotate in degrees, invert, opacity, saturate, sepia, and a drop-shadow with X, Y, blur, color, and alpha controls. Toggle each function with a checkbox, drag the slider for its value, and the live preview updates immediately. Presets cover the most common starting points: a classic Frosted material, an iOS Material with vivid saturation, Heavy Fog for full-screen modal scrims, a Subtle Nav for sticky navigation, a Dark Glass variant for dark-mode UIs, a cool Frozen tone, a Vintage Print sepia, a Newspaper grayscale, and a Spotlight option that uses only the drop shadow function. The preview surface switches between Card, Pill, Nav bar, and Modal shapes and mounts over five different backdrops (a colorful photo simulation, a vivid gradient, a neon scene, a dark wall, and a light wall) so the chosen value can be sanity-checked against the contexts you actually ship. A surface tint slider sets the translucent fill that almost every real backdrop-filter usage pairs with the filter, so the preview matches what production code will look like. The tool emits three copy-ready outputs. The CSS block pairs the standard backdrop-filter with the -webkit-backdrop-filter fallback Safari and recent Android WebViews still require to render the blur. The React inline style object uses camelCase keys including WebkitBackdropFilter so it pastes directly into a style prop. The Tailwind class uses v3+ arbitrary-value syntax with the backdrop- prefix so it pastes into JSX without writing a tailwind.config.js entry. Notes on browser support, GPU compositing, and accessibility live at the bottom of the page so the value you ship reads well, performs on real devices, and never traps low-contrast text against a busy background. Everything is local. The values you set are component state and the copy helpers use your browser clipboard. Nothing is uploaded.
