SVG Optimization Best Practices for Web (2025)

SVG is the native format for scalable web graphics — icons, logos, charts, illustrations — and it's often the most overlooked performance opportunity on a page. A fresh Figma export can be 10x larger than it needs to be. This guide covers how to optimize SVGs systematically: automated tools, manual techniques, delivery strategies, and common mistakes to avoid. Why SVG Optimization Matters An unoptimized SVG from a design tool contains: Editor metadata ( <sodipodi:namedview> , <dc:format> , etc.) Unused definitions and symbols Redundant id attributes Default attribute values that browsers assume anyway Unnecessary whitespace and comments Verbose path data (more decimal places than needed) Empty groups and redundant transform attributes A typical Figma icon export might be 4KB. After optimization: 800 bytes. Multiply that across 50 icons on a page. Tool 1: SVGO (The Standard) SVGO (SVG Optimizer) is the industry standard for SVG optimization. It's what most other tools use under the hood
