How much can SVG optimization reduce file size?

Typically 30-60% for SVGs exported from design tools. Files with heavy metadata (Illustrator exports) see the largest reductions. Already-clean SVGs see smaller improvements.

Does SVG optimization change the visual output?

No. Optimization removes only invisible metadata, comments, and redundant code. The rendered image is identical before and after optimization.

Should I inline SVGs or use external files?

Inline for small icons and UI elements (faster, CSS-stylable). External files for complex illustrations and graphics used across multiple pages (cacheable).
