A small JavaScript library that composites multiple images into one, abstracting away canvas boilerplate into a single promise-based function call. It supports positioning, opacity, and custom dimensions, and works in both the browser and Node.js.

Use cases

• merge multiple png images into one in the browser
• overlay images on top of each other with x/y positions
• compose avatar layers without writing canvas code
• generate a base64 data uri from combined images
• stack images with per-image opacity
• combine images server-side in node.js

When to choose

• you need simple image merging/compositing without manual canvas handling
• you want a lightweight promise-based API returning a base64 image
• you need the same code to work in browser and Node.js

When to avoid

• you need advanced image editing like filters, resizing, or format conversion
• you're doing heavy server-side image processing where a native library like sharp is better
• you need non-canvas output formats or streaming
