## What it is
smartcrop.js is a JavaScript library that implements a content-aware algorithm to find good crops for images. It runs in the browser, in Node.js, or via a CLI, and returns the optimal crop rectangle for a requested width and height.

## Use cases
- automatically crop photos to thumbnails without cutting off faces
- generate smart square crops for image galleries
- crop user-uploaded images for social media previews
- create Ken Burns slideshow transitions from photos
- batch-crop images from the command line
- avoid center-crop failures in responsive image pipelines

## When to choose
- you need automatic, content-aware image cropping in JavaScript
- you want a lightweight, dependency-free algorithm that works in browser and Node
- you need to integrate cropping with sharp or GraphicsMagick in Node

## When to avoid
- you need ML-based face detection accuracy out of the box
- you work outside the JavaScript ecosystem
- you need full image editing rather than crop suggestions
