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
