SVG Optimizer: Reduce SVG File Size Online

Optimize SVG Files Online

SVG files from design tools often contain metadata, comments, and editor-specific attributes that add 10-40% overhead. This optimizer uses SVGO running entirely in your browser to strip unnecessary data while preserving visual quality. No files are uploaded, no server processing, no waiting.

How to Use

1. Paste SVG code into the textarea or upload an SVG file
2. The tool automatically switches to the Optimize tab
3. Choose a preset: Conservative, Moderate, or Aggressive
4. Click Optimize SVG to process the file
5. Compare the before/after sizes and download the optimized version

Optimization Presets

• Conservative: removes comments, metadata, and editor namespaces. Safe for almost all SVGs.
• Moderate: also collapses groups, converts colors, merges paths, and simplifies numeric values.
• Aggressive: maximum compression. May remove viewBox and title elements. Check the preview before downloading.
• Custom: toggle individual SVGO plugins for fine-grained control.

Common Use Cases

Clean up exports from design tools

Figma, Sketch, and Illustrator embed metadata that adds overhead. Run exports through the Moderate optimizer before committing to a repo or deploying to production.

Reduce SVG size for faster page loads

Smaller SVG files load faster and use less bandwidth. Optimizing your icon sprites and illustrations can save 30-70% on file size without visible quality loss.

Prepare SVGs for email HTML

Email clients have strict size limits. Optimize SVGs before embedding them in email templates to stay within limits while maintaining visual quality.
