Cropper

A client-side image and video cropper with drag, wheel, keyboard, pinch, and gesture controls. It exposes crop coordinates, zoom, rotation, crop-area measurements, and media-loading callbacks while providing composable image, video, and crop-area primitives.

Installation

pnpm dlx shadcn@latest add https://diceui.com/r/radix-vega/cropper.json

Usage

usage.tsx
import { Cropper, CropperArea, CropperImage } from "@/components/ui/cropper";export function AvatarCropper() {  return (    <div className="h-96 w-full">      <Cropper aspectRatio={1} shape="circle" withGrid>        <CropperImage src="/avatar.jpg" alt="Profile photo" />        <CropperArea />      </Cropper>    </div>  );}
  • Profile avatars, cover images, product photos, and other image-upload workflows.
  • Video thumbnail or poster-frame selection with pinch and gesture support.
  • Interfaces that need controlled crop, zoom, rotation, or pixel/percentage crop output.
  • When a crop overlay should be composed from separate image, video, and selection-area primitives.

Examples

Controlled crop and zoom

Control the crop position and zoom while receiving percentage and pixel crop results.

controlled-crop-and-zoom.tsx
import * as React from "react";import { Cropper, CropperArea, CropperImage, type CropperPoint } from "@/components/ui/cropper";export function ControlledCropper() {  const [crop, setCrop] = React.useState<CropperPoint>({ x: 0, y: 0 });  const [zoom, setZoom] = React.useState(1);  return (    <div className="h-[28rem] w-full">      <Cropper        crop={crop}        zoom={zoom}        aspectRatio={16 / 9}        onCropChange={setCrop}        onZoomChange={setZoom}        onCropComplete={(area, areaPixels) => {          console.log(area, areaPixels);        }}      >        <CropperImage src="/landscape.jpg" alt="Landscape" />        <CropperArea withGrid />      </Cropper>    </div>  );}

Circular avatar crop

Use a circular selection with a constrained square aspect ratio.

circular-avatar-crop.tsx
import { Cropper, CropperArea, CropperImage } from "@/components/ui/cropper";export function CircularAvatarCropper() {  return (    <div className="size-96">      <Cropper aspectRatio={1} shape="circle" objectFit="cover">        <CropperImage src="/person.jpg" alt="Person" />        <CropperArea />      </Cropper>    </div>  );}

Video cropper

Crop a muted, looping video and prevent wheel-based zoom when required by the surrounding UI.

video-cropper.tsx
import { Cropper, CropperArea, CropperVideo } from "@/components/ui/cropper";export function VideoCropper() {  return (    <div className="h-[28rem] w-full">      <Cropper aspectRatio={16 / 9} preventScrollZoom withGrid>        <CropperVideo src="/preview.mp4" aria-label="Video preview" />        <CropperArea />      </Cropper>    </div>  );}

withGridbooleanfalseEnables the rule-of-thirds grid on a descendant CropperArea unless overridden there.
onCropChange(crop: CropperPoint) => voidnullCalled when the crop position changes.
onCropSizeChange(cropSize: CropperSize) => voidnullCalled when the calculated crop-area size changes.
onCropAreaChange(croppedArea: CropperAreaData, croppedAreaPixels: CropperAreaData) => voidnullCalled on animation frames while crop, zoom, rotation, or media sizing changes.

Accessibility

  • The interactive cropper root is a focusable div with tabIndex={0}; it supports ArrowUp, ArrowDown, ArrowLeft, and ArrowRight for crop movement, with Shift reducing the step to 20%.
  • Add an accessible name such as aria-label="Adjust crop area" to Cropper or an asChild root, because the component does not provide an aria-label or role automatically.
  • Provide meaningful alt text on CropperImage. For CropperVideo, provide an accessible label or other suitable alternative because the component does not add one.
  • The selection overlay is visual only and does not expose its dimensions or shape through ARIA. Surface crop coordinates, zoom, or status separately if users need those values announced.
  • The component uses preventDefault for touch movement, wheel zoom, and gesture handling; verify keyboard and non-pointer controls in the surrounding workflow.
