svg/svgo

SVGO (SVG Optimizer) is a Node.js tool that shrinks SVG files by removing unnecessary content without changing how the image looks. SVG is a file format for vector graphics, logos, icons, illustrations, and when designers export SVGs from tools like Illustrator or Figma, the files often include editor metadata, redundant attributes, hidden elements, and bloat that serves no purpose in a finished website or app. SVGO strips all of that out automatically. It works through a plugin system where each plugin handles a specific type of cleanup, removing comments, collapsing empty groups, converting colors to shorter formats, and so on. You can use the default set of plugins or customize which ones run and how. You configure it with a simple config file or pass options directly on the command line. You would use SVGO when you want to reduce page load times by sending smaller SVG assets to the browser, or as part of a build pipeline that prepares assets for production. It can process individual files, whole directories, or be integrated into a JavaScript project as a library and called programmatically. The tool runs on Node.js, is available via npm, and works both as a command-line application and as an importable JavaScript module.
