zopflipng

ZopfliPNG is a command line tool for optimizing PNG images. It is based on the Zopfli compression algorithm, which is known for its high compression ratio. This tool uses a combination of different techniques to achieve better compression without sacrificing image quality. ZopfliPNG works by optimizing the deflate compression method used in PNG files. It rearranges the compressed data, applies better entropy coding, and eliminates unnecessary information. The tool can achieve significant reductions in file size, making it perfect for web developers and designers who want to improve page load times. ZopfliPNG is open source and can be easily integrated into existing workflows. It supports both lossless and lossy compression, allowing users to choose the level of optimization they require. The tool is highly configurable, with options to control various aspects of the optimization process. Overall, ZopfliPNG is a powerful command line tool for reducing the size of PNG images while maintaining their visual fidelity.
