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
