Thumbnailer.js

Thumbnailer.js is an image minifier for Node.js that optimizes images to reduce file size while maintaining quality. Version 1.0.3 is the current stable release, with no frequent updates. It supports CLI usage, programmatic API, and Express middleware for on-demand processing. Key differentiators include batch processing, support for JPEG, PNG, and WebP formats, and TypeScript definitions included. Compared to sharp or imagemin, it offers a simpler API and built-in CLI, but is more limited in format support and performance.
