Cropper File Upload Demo
A client-side image upload example that accepts up to two images, displays file metadata and previews, and lets users crop each image before applying the result. Cropping uses a circular 1:1 area, canvas-generated PNG output, and a zoom control from 1× to 3×.

Usage
usage.tsx
import CropperFileUploadDemo from "@/components/cropper-file-upload-demo";export default function Example() { return <CropperFileUploadDemo />;}- Avatar or profile-image upload flows that require a consistent circular crop.
- Forms where users can upload and edit one or two image files before submission.
- Media-management interfaces that need drag-and-drop upload, previews, deletion, and client-side cropping.
- Settings or onboarding screens where image output should be normalized to PNG dimensions selected by the crop area.
Examples
Profile avatar upload
Use the demo as the image input in a profile settings form.
profile-avatar-upload.tsx
import CropperFileUploadDemo from "@/components/cropper-file-upload-demo";export function ProfileAvatarUpload() { return ( <section className="space-y-3"> <div> <h2 className="text-lg font-semibold">Profile photo</h2> <p className="text-sm text-muted-foreground"> Upload and crop up to two photos. </p> </div> <CropperFileUploadDemo /> </section> );}Team member onboarding
Place the uploader in an onboarding card for a new team member.
team-member-onboarding.tsx
import CropperFileUploadDemo from "@/components/cropper-file-upload-demo";export function TeamMemberOnboarding() { return ( <div className="rounded-lg border p-6"> <h1 className="mb-1 text-xl font-semibold">Add team photos</h1> <p className="mb-5 text-sm text-muted-foreground"> Choose images and adjust their crop before continuing. </p> <CropperFileUploadDemo /> </div> );}Product image preparation
Use the component in a product-editing workspace before saving product media.
product-image-preparation.tsx
import CropperFileUploadDemo from "@/components/cropper-file-upload-demo";export function ProductImagePreparation() { return ( <main className="grid gap-6 lg:grid-cols-[minmax(0,1fr)_20rem]"> <div> <h2 className="text-lg font-semibold">Product images</h2> <p className="mt-1 text-sm text-muted-foreground"> Upload up to two source images and crop them for your catalog. </p> <div className="mt-4"> <CropperFileUploadDemo /> </div> </div> <aside className="rounded-md bg-muted/50 p-4 text-sm"> Cropped files are generated in the browser as PNG files. </aside> </main> );}API reference
PropTypeDefaultDescription
propsnull—The exported CropperFileUploadDemo component does not declare or accept any props.
Accessibility
- The crop dialog uses DialogTitle and DialogDescription, providing an accessible modal name and description.
- Uploaded image previews receive alt text from the original file name.
- The crop area is presented inside a labeled dialog, and the zoom value is exposed in visible text next to the slider.
- The crop, reset, choose-files, and delete controls are icon-oriented; add accessible names such as aria-label when adapting the example, especially for the Crop and Delete icon buttons.
- The example uses a visible dropzone instruction and a native file-upload trigger, but keyboard and screen-reader behavior should be verified with the installed FileUpload primitive.
- The preview implementation creates object URLs for cropped previews without revoking each preview URL; production adaptations should revoke those URLs when previews are replaced or removed.
