## What it is
A lightweight cross-platform Node.js library (native C++ addon) for decoding PNG/JPEG/GIF images and encoding PNG/JPEG images. It provides a jQuery-like chaining API for loading, resizing, drawing, and saving images without external image library dependencies.

## Use cases
- resize images in nodejs
- convert png to jpeg in node
- add a watermark logo to an image
- decode gif files in nodejs
- compress jpeg images with quality settings
- process uploaded images without installing imagemagick

## When to choose
- you need lightweight image decode/encode in Node.js with no external dependencies
- you want a simple chaining API for basic resize, draw, and save operations
- you only need PNG/JPEG/GIF support

## When to avoid
- you need advanced image manipulation like filters, color spaces, or many formats (use sharp instead)
- you need active development or support for the latest Node.js versions
- you need 32-bit platform support

## Facets
- artifact type: library
- maturity: maintenance
- function: image-processing
- domain: image-processing, web-development
- platform: windows
- tags: image-decoder, image-encoder, native-addon, cpp, png, jpeg, gif, chaining-api, nodejs, macos, linux
