The baoyu-compress-image skill provides a streamlined solution for compressing and optimizing images, converting them primarily to WebP format or optionally to PNG and JPEG. It automatically selects the most efficient available tool on the system, including sips, cwebp, ImageMagick, or Sharp, to achieve significant file size reductions while maintaining quality. This skill addresses the common challenge of managing large image files, improving website load times, and reducing storage usage without requiring manual intervention or extensive technical knowledge from the user.

Key features of baoyu-compress-image include automatic tool selection based on availability, flexible input handling for single files or entire directories, and customizable output options such as format, quality, and recursive processing. Users can also choose to retain the original file, generate JSON output for automated workflows, and leverage custom configurations through EXTEND.md for default format, quality, and preservation preferences. The skill provides a command-line interface using bun or npx, ensuring compatibility across macOS, Linux, WSL, Git Bash, and Windows PowerShell environments.

This skill is particularly useful for web developers, content creators, and system administrators who need to optimize large numbers of images efficiently. Common use cases include reducing image file sizes for websites and apps to improve performance, converting legacy images to modern formats for better compression, and maintaining a consistent image quality across projects. Its straightforward CLI interface and support for both single images and directories make it accessible for both individual and automated batch workflows.
