SVG Optimizer: Clean & Compress SVG Files Without Breaking Them

SVGs exported from tools like Figma, Illustrator, or Sketch often contain unnecessary metadata, comments, and unused definitions that bloat file size.

I’ve built a browser-based SVG Optimizer that cleans and compresses SVG files without changing their visual appearance.

Why optimize SVGs?

• Faster page loads — smaller files download and parse quicker
• Better Core Web Vitals & Lighthouse scores
• Cleaner, more readable SVG code
• Smaller JS/CSS bundles overall

How it works

1. Paste SVG code, upload a file, or load a sample
2. Choose an optimization preset:
   • Default
   • Max Optimized
   • Low Optimization
   • Manual
3. Click Optimize SVG
4. Copy or download the optimized result

Features

• 100% client-side (no uploads, no servers)
• Preset modes for quick optimization
• Manual controls for advanced use cases
• Decimal precision control (0–6)
• Before/after size comparison
• Safe optimization — preserves viewBox & paths

Perfect for preparing SVGs for production and improving frontend performance.
