PNG Decoder for Node.js and Browser

png-js is a JavaScript-based PNG decoder designed for both Node.js and browser environments. The package's latest version, 2.0.0, was released over a decade ago (tagged in 2013, with the last npm publish for version 1.0.0 being over six years ago), indicating it is an abandoned project with no active maintenance or release cadence. While it provides basic functionality for decoding PNG files into raw pixel data, its age means it does not support modern JavaScript module systems like ESM, lacks official TypeScript definitions, and likely misses performance optimizations or features found in contemporary image processing libraries. Developers requiring a robust, actively maintained, or high-performance PNG solution should consider modern alternatives such as 'pngjs' (note the lowercase 'js'), 'sharp', or 'jimp'. Its key differentiator was being a pure JavaScript decoder for both environments at a time when fewer options existed.
