Oxipng is a multithreaded, lossless PNG/APNG compression optimizer written in Rust. It can be used as a command-line utility or as a Rust library, offering configurable optimization levels and metadata stripping.
Use cases
- compress png images without losing quality
- optimize pngs for faster website loading
- strip metadata from png files
- reduce png file size in a build pipeline
- batch optimize png images from the command line
- shrink pngs with transparency for the web
When to choose
- you need lossless PNG compression with fast, multithreaded performance
- you want a CLI tool that integrates easily into build or CI pipelines
- you need a Rust library for programmatic PNG optimization
- you want configurable trade-offs between speed and compression level
When to avoid
- you need to optimize JPEG, WebP, or other non-PNG formats
- you require lossy image compression for maximum size reduction
- you need a GUI-based image optimizer
