SVGO

SVGO is a Node.js library and command‑line tool that reduces the size of SVG files by removing unnecessary data such as editor metadata, comments, hidden elements, and suboptimal attribute values. It parses SVG markup, applies a series of built‑in or user‑defined plugins, and writes a cleaned, smaller version that renders identically to the original.

The tool can be installed globally or locally and used directly from the terminal to process individual files or entire directories with recursive options. Configuration is supplied via an `svgo.config.mjs` file or command‑line flags, allowing users to enable, disable, or customize plugins, including the default preset and custom extensions.

Developers can also integrate SVGO programmatically by importing its `optimize` function or loading configuration files, making it suitable for build pipelines, asset pipelines, or any workflow that needs automated SVG optimization. The project is released under the MIT license.
