SVG image assets are automatically optimized with SVGO. It's a Node.js-based tool which converts SVG-as-XML data into SVG-as-JS AST representation. The result? Lightweight vector shape file made only from the actual curves, no extra stuff like the editor metadata. As the matter of fact, the SVGO optimization can save up to 80% of file size.
