imgproxy is a standalone server built with Go and libvips for fast, secure image resizing and conversion. It handles remote image processing with built-in protection against image bombs and denial-of-service attacks through URL signatures and dimension checks. The tool prioritizes simplicity by focusing on core image processing features while delegating concerns like caching and HTTPS to external infrastructure. Benchmarks show significant performance advantages due to libvips' efficiency and Go's native HTTP handling.
