SVG Optimizer
SVG optimization reduces file size by removing whitespace, comments, XML declarations, and unnecessary attributes without affecting visual appearance. Minify mode removes all non-essential data for production deployment (typical savings: 20-80% depending on source). Prettify mode adds indentation and line breaks for development and code readability. SVG optimization improves page load speed, reduces bandwidth costs, and enhances Core Web Vitals scores. Design tool exports (Illustrator, Figma) contain significant metadata that optimization removes. For advanced optimization (path simplification, decimal precision), use SVGO or specialized tools.
Optimize and compress SVG files by removing unnecessary whitespace, comments, and formatting. Minify SVG to reduce file size for faster page loads, or prettify SVG code for easier editing and debugging. Real-time optimization with byte savings statistics. Works entirely in your browser - no server uploads.
SVG Optimizer
About SVG Optimization
Minify mode removes unnecessary whitespace, comments, and formatting to create the smallest possible file size. Perfect for production use where every byte counts.
Prettify mode adds proper indentation and line breaks to make SVG code human-readable and easier to edit. Useful for development and debugging.
This tool provides basic optimization. For advanced optimization including path simplification, color optimization, and attribute removal, consider using SVGO or other specialized tools.

Frequently Asked Questions
- What is SVG optimization and why should I optimize SVG files?
- SVG optimization removes unnecessary data from SVG files without affecting visual appearance. Optimized SVGs load faster (crucial for page speed and Core Web Vitals), reduce bandwidth costs, and improve performance on mobile devices. Typical savings: 20-50% for hand-coded SVGs, 50-80% for SVGs exported from design tools like Illustrator or Figma (which add metadata, comments, and editor-specific data). For production websites, always optimize SVGs before deployment.
- How much file size reduction can I expect from SVG optimization?
- File size reduction depends on the source: Hand-coded SVGs: 10-30% (removing whitespace, shortening decimals), Design tool exports (Illustrator, Figma, Sketch): 50-80% (removing metadata, hidden layers, comments, editor IDs), Unoptimized SVGs with inline styles: 40-60%. Example: A 10KB Illustrator-exported SVG can shrink to 2-3KB after optimization. Use minify mode for maximum reduction. Prettify mode increases file size slightly (+5-10%) by adding whitespace for readability.
- What does minify mode remove from my SVG?
- Minify mode removes: Whitespace (spaces, tabs, newlines between tags), Comments (<!-- ... -->), XML declaration (<?xml ...?>), Unnecessary quotes and spaces in attributes, Default attribute values. It preserves all visual elements: paths, shapes, colors, transforms, gradients. Your SVG will look identical but load faster. For advanced optimization (path simplification, decimal precision, unused IDs), use specialized tools like SVGO or Squoosh.
- When should I use minify mode vs prettify mode?
- Use minify mode for production: deploying to websites, mobile apps, or any public-facing use. Maximizes page speed and reduces bandwidth. Use prettify mode for development: editing SVG code manually, debugging path issues, learning SVG structure, or sharing code with teammates. Adds indentation and line breaks for readability. Workflow: export from design tool → optimize/minify → deploy to production. Keep an unminified copy for future edits.
- Will SVG optimization break my graphics or cause visual changes?
- No, basic optimization (whitespace removal, comment deletion) is 100% safe and produces identical visual output. This tool performs safe, non-destructive optimization. Advanced optimization (not included here) like path simplification, decimal rounding, or color optimization can cause minor visual differences. Always test optimized SVGs in your target browsers. For mission-critical graphics (logos, icons), visually compare before and after using browser dev tools or design software.
- Are there more advanced SVG optimization tools?
- Yes, for deeper optimization use: SVGO (command-line tool, Node.js library) - removes unused IDs, optimizes paths, merges paths, reduces decimal precision. Configurable plugins. Squoosh (web app) - Google's image optimizer with SVG support. SVGOMG (web GUI for SVGO) - visual interface to toggle optimization options. ImageOptim (macOS), TinyPNG (web) - batch optimization. This tool provides basic minification; for production pipelines, integrate SVGO into your build process (webpack, Vite, Rollup).
