SVGs exported from design tools contain unnecessary metadata, comments, and redundant code—optimization removes this bloat, often cutting file size in half.
Check if SVG files are optimized by removing unnecessary metadata and formatting.
Optimize SVG files using SVGO or similar tools to reduce file size.
Explain how SVG optimization can reduce file sizes by 50-80% without quality loss.
Review image assets, markup, and delivery configuration related to Optimize SVG files. Flag exact files or components where format choice, sizing, or loading behavior violates the rule, and describe how to confirm the fix in DevTools.
