- Let users compare an original photograph with a processed, color-adjusted, or generated version.
- Use in product demos where the comparison position must be controlled by React state.
- Present visual QA, restoration, retouching, or design iteration results.
Examples
Photo enhancement comparison
Compare an unedited landscape with a brighter, color-enhanced version.
photo-enhancement-comparison.tsx
import * as React from "react";import { CompareSlider, CompareSliderAfter, CompareSliderBefore, CompareSliderHandle,} from "@/registry/bases/radix/ui/compare-slider";export default function PhotoEnhancementComparison() { const [value, setValue] = React.useState(30); return ( <CompareSlider value={value} onValueChange={setValue} className="h-[400px] overflow-hidden rounded-lg border"> <CompareSliderBefore label="Original"> <img src="/photos/original-landscape.jpg" alt="Original landscape" className="size-full object-cover" /> </CompareSliderBefore> <CompareSliderAfter label="Enhanced"> <img src="/photos/enhanced-landscape.jpg" alt="Enhanced landscape" className="size-full object-cover" /> </CompareSliderAfter> <CompareSliderHandle /> </CompareSlider> );}Before-and-after retouching
Show the difference between an untouched portrait and a retouched result.
before-and-after-retouching.tsx
import * as React from "react";import { CompareSlider, CompareSliderAfter, CompareSliderBefore, CompareSliderHandle,} from "@/registry/bases/radix/ui/compare-slider";export default function PortraitRetouchComparison() { const [value, setValue] = React.useState(50); return ( <CompareSlider value={value} onValueChange={setValue} className="h-[400px] overflow-hidden rounded-lg border"> <CompareSliderBefore label="Before"> <img src="/portraits/before.jpg" alt="Portrait before retouching" className="size-full object-cover" /> </CompareSliderBefore> <CompareSliderAfter label="After"> <img src="/portraits/after.jpg" alt="Portrait after retouching" className="size-full object-cover" /> </CompareSliderAfter> <CompareSliderHandle /> </CompareSlider> );}Generated image comparison
Compare a source image with an AI-generated or upscaled result.
generated-image-comparison.tsx
import * as React from "react";import { CompareSlider, CompareSliderAfter, CompareSliderBefore, CompareSliderHandle,} from "@/registry/bases/radix/ui/compare-slider";export default function GeneratedImageComparison() { const [value, setValue] = React.useState(30); return ( <CompareSlider value={value} onValueChange={setValue} className="h-[400px] overflow-hidden rounded-lg border"> <CompareSliderBefore label="Source"> <img src="/images/source.jpg" alt="Source image" className="size-full object-cover" /> </CompareSliderBefore> <CompareSliderAfter label="Generated"> <img src="/images/generated.jpg" alt="Generated image" className="size-full object-cover" /> </CompareSliderAfter> <CompareSliderHandle /> </CompareSlider> );}Accessibility
- The comparison regions expose descriptive `label` values: "Original" and "Enhanced".
- Both images include meaningful `alt` text that identifies the comparison state.
- The controlled value is updated through `onValueChange`, allowing the parent to preserve and synchronize the slider position.
- Keep the comparison handle keyboard-operable through the underlying slider implementation, and ensure the handle remains visible against both image regions.
- Use sufficiently descriptive labels and image alternatives when replacing the demo content.
