About:
Oxipng is a command-line utility that optimizes PNG images to reduce their file size without losing quality. It uses lossless compression techniques to strip metadata and recompress data streams. This results in faster loading web assets and reduced storage costs.

Key Features:

Multithreaded processing for high-speed optimization
Lossless compression preserving image quality
Strip metadata and ancillary chunks
Interlacing support
Cross-platform binary

Use Cases:

Optimizing assets for web development
Reducing storage usage for image libraries
Automating image processing in CI/CD pipelines

Alternatives:

optipng – Oxipng is generally faster and supports multithreading, whereas optipng is older and single-threaded.
pngcrush – Oxipng offers a more modern approach with a wider variety of compression strategies.
