SVGO is a Node.js library and command-line tool for optimizing SVG files by removing redundant information and converting suboptimal values.
SVG files exported from vector editors typically contain unnecessary metadata, comments, hidden elements, and default values that increase file size without affecting rendering. SVGO solves this by parsing SVG files and applying a series of optimization transformations. The tool uses a plugin architecture where each plugin handles a specific optimization task, and plugins run in a defined sequence to safely remove or simplify SVG content.
The tool suits projects where SVG file size matters, such as web applications serving many icons or graphics, or build pipelines that need automated SVG processing. SVGO works both as a standalone command-line utility for batch processing directories of files and as a Node.js library that can be embedded in other tools. Developers can use the default preset of plugins for common optimizations or customize behavior by disabling specific plugins, adjusting their parameters, or writing custom plugins. The project provides configuration through JavaScript config files and command-line options, making it flexible for different workflows.
Development activity shows consistent engagement with the codebase through regular updates and maintenance. The project maintains active documentation and provides multiple installation methods across package managers. Community support is facilitated through a dedicated Discord channel for user discussion and assistance.
