SVGO (SVG Optimizer) is a powerful Node.js library and command-line tool designed to reduce SVG file sizes by removing unnecessary data. Vector editor exports often contain redundant information like metadata, comments, hidden elements, and default values that don't affect how the SVG renders.

Key capabilities include:

Batch processing - Optimize single files or entire directories recursively
Plugin architecture - Customize optimization with built-in plugins or create custom ones
Flexible configuration - Configure via svgo.config.mjs or command-line options
API access - Use the optimize() function in your Node.js projects
Multipass optimization - Run multiple optimization passes for maximum compression
Data URI encoding - Convert images to base64 or other encoded formats

Install globally for command-line use or add to your project dependencies. The default preset includes optimized settings for most use cases, but you can customize individual plugins or disable specific optimizations as needed. Perfect for reducing SVG assets in web projects, design systems, and icon libraries.
