Optimize SVG files
SVGs exported from design tools contain unnecessary metadata, comments, and redundant code—optimization removes this bloat, often cutting file size in half.
Quick Reference
- SVGO can reduce SVG file size by 50-80%
- Removes editor metadata, comments, and redundant attributes
- Preserve viewBox and accessibility attributes
- Integrate into build process for automatic optimization
Check
Check if SVG files are optimized by removing unnecessary metadata and formatting.
Fix
Optimize SVG files using SVGO or similar tools to reduce file size.
Explain
Explain how SVG optimization can reduce file sizes by 50-80% without quality loss.
Code Review
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.
