    Examples

    Instagram Ludwig — bright, contrasty, lightly saturated

    Input
    Contrast 110% · Brightness 110% · Saturate 130% (all others at default)
    Output
    filter: brightness(110%) contrast(110%) saturate(130%);

    Only non-default filters are emitted, and the order is the documented 'brightness → contrast → saturate' chain. The rule is a single-line drop-in for any stylesheet.

    Black & White with extra punch

    Input
    Grayscale 100% · Contrast 120% (all others at default)
    Output
    filter: contrast(120%) grayscale(100%);

    Two filters is all this preset needs. The generator keeps them sorted, so re-ordering the sliders does not change the produced string — useful when you A/B test combinations quickly.

    Cool Tone — hue-rotate 180°

    Input
    Hue-rotate 180deg · Saturate 110% · Brightness 105% (all others at default)
    Output
    filter: brightness(105%) saturate(110%) hue-rotate(180deg);

    The 180° hue rotation flips each colour to its complementary colour — produces a unified 'cool' cast. The generator keeps every value paired with its unit (percent vs degrees) so the output is identical across runs.

    About this tool

    The CSS filter property turns a real-time image pipeline into a one-line style rule: brightness, contrast, saturate, hue-rotate, blur, grayscale, sepia, opacity, invert, and drop-shadow can be stacked in any order, applied to any element, and animated freely. Manually typing a long filter chain is error-prone — order changes the result, every numeric value needs a unit, and drop-shadow alone takes four offsets plus a color. The generator exposes each property as a labelled slider with the unit built in, plus ten named presets inspired by Instagram, vintage, B&W, dramatic and dreamy filters so you can start a styling session with one click.

    The generator covers 10 filters in three tabs (Basic / Color / Advanced) and emits four output formats: a plain CSS `filter: …;` declaration, an SCSS variable, a JavaScript style object, and a React `const style = {…}` snippet — ready to paste into stylesheets, ES modules, or JSX `style={style}` props. A side-by-side / overlay preview on one of six Unsplash sample images (portrait, landscape, urban, food, architecture, abstract) lets you verify the look on a real photo, and an upload switch lets you swap in your own image (read locally, never uploaded).

    The drop-shadow tab mirrors the box-shadow generator: independent Offset X / Offset Y / Blur sliders plus a Color picker and an opacity slider that combine into an 8-digit hex notation (#RRGGBBAA) so colors blend correctly over arbitrary backgrounds. Custom presets save the current combination of filter values under a name and reload them with one click. All computation happens locally; the image and CSS are never sent to a server.

    How to use

    1. Pick a preset or start from zero

      Click one of the ten built-in presets (Ludwig, Clarendon, Vintage, B&W, High Contrast, Warm Tone, Cool Tone, Dreamy, Dramatic, Soft Focus) or use the Random button to spark an idea.

    2. Drag the sliders to refine

      Switch between Basic, Color and Advanced tabs. Each slider shows its current value plus unit. Only non-default values are emitted into the CSS so the final rule stays tidy.

    3. Configure a drop shadow

      In the Advanced tab, raise the drop-shadow value above 0 and dial in Offset X, Offset Y, Blur, Color and Opacity. The opacity is encoded as the alpha byte (#RRGGBBAA) so shadow color matches the surrounding style.

    4. Pick an output format

      Switch between CSS, SCSS, JavaScript and React Style. The text box updates immediately and the Copy button writes the active format to the clipboard.

    5. Save custom presets

      Type a name in the Save Current box and click Save. The custom preset appears in the saved list and can be reapplied at any time during the session.

    Use cases

    Theming a hero image without a Photoshop round-trip

    Apply a Ludwig-style filter directly to the <img> or background-image element and you skip the export-and-replace step; the same effect becomes a CSS variable you can reuse on any image in the design system.

    Building a hover-state look-and-feel

    Pair the filter pipeline with a transition (`transition: filter .2s ease`) and you get a polished hover effect — desaturate on rest, full colour on hover, all without an external asset.

    Producing a styled React component

    Switch the output format to React Style, copy the generated object, and pass it straight into a component's style prop. The format keeps numeric values unquoted and the filter string quoted the way React expects.

    Generating a reusable SCSS token

    Switch the output to SCSS and drop the line into a `_filters.scss` partial so every component can `@use` the same $filter-effect value. The token is regenerated identically each time the sliders are reused.

    Common mistakes

    Mistake:Animating `filter` with a list of values that changes length during the transition.

    Fix:Browsers interpolate filter functions position-by-position, so `brightness(100%) saturate(100%) → brightness(120%) saturate(140%)` works, but adding or removing a function mid-animation causes a hard cut. Keep the list length constant across the transition.

    Mistake:Reaching for opacity instead of an explicit alpha channel on the surrounding element.

    Fix:`filter: opacity(0)` removes the element from the hit-test and from accessibility tools; it is not a substitute for a transparency layer. Use the underlying `opacity` property or a transparent background if you need click-through behaviour.

    Mistake:Assuming `drop-shadow` will draw a halo around a transparent PNG the same way `box-shadow` does.

    Fix:`drop-shadow` follows the alpha channel of the actual rendered shape, while `box-shadow` draws around the element's box. Use drop-shadow when the asset is irregular (icons, illustrations) and box-shadow when you want a rectangular border-like glow.

    Mistake:Stacking too many filters and blaming the GPU.

    Fix:Browsers re-rasterise the filtered element on every paint, so a long filter chain or a filter applied to a full-viewport element can cost frames. Apply filters to small elements first, or pre-bake heavy effects into an asset.

    Mistake:Forgetting the `hue-rotate` value carries a unit, while every other filter expects a percent.

    Fix:`hue-rotate(180deg)` rotates 180°, but `hue-rotate(50%)` is also legal (resolves to 180°) and the inverse — `hue-rotate(50deg)` does nothing because the unit is wrong. Verify the unit before assuming an animation is misconfigured.
