## What it is
Cropper.js is a JavaScript library for cropping images in the browser, built as customizable, extensible web components. The related 'cropper' package is a jQuery plugin wrapper around the same cropping functionality.

## Use cases
- crop user-uploaded profile pictures in the browser
- let users select and crop an image region before upload
- rotate, zoom, and scale images interactively on a web page
- build an avatar editor with aspect ratio constraints
- crop images in a React, Vue, or Angular app

## When to avoid
- you need server-side or batch image processing
- you need full image editing beyond cropping, rotating, and scaling
- your project does not run in a browser

## Facets
- artifact type: library
- maturity: stable
- function: image-processing, ui-components
- domain: image-processing, frontend, web-development
- platform: browser
- tags: image-cropper, web-component, custom-element, jquery-plugin, typescript, javascript, web
