SVG Minifier

SVG Minifier is a professional vector graphics optimization tool based on the SVGO engine that significantly reduces SVG file size while maintaining visual quality, improving web page loading speed and user experience.

Core Features

• Batch Compression: Supports processing multiple SVG files simultaneously
• Real-time Preview: Instantly view optimization effects and compression ratios
• Flexible Configuration: 50+ customizable optimization options
• Code Viewing: Supports previewing and copying optimized SVG code
• Secure and Private: Runs entirely locally in the browser, files are not uploaded to servers

How to Use

1. Upload one or more SVG files
2. Tool automatically performs optimization processing
3. View optimization results including file size changes and savings percentage
4. Click the code area to copy optimized SVG code
5. Switch display modes to toggle between grid preview and code view

Basic Configuration

Multi-pass Processing

Perform multiple rounds of optimization on SVG files for further compression. Recommended to enable for best results.

Prettify Code

Format the output SVG code to improve readability. Suitable for scenarios requiring manual editing.

View SVG Code

Toggle between grid preview mode and full code view display.

Optimization Options

Click the "Features" panel to expand detailed configuration. The tool defaults to enabling safe and commonly used optimization options:

Cleanup Optimization

• Remove redundant whitespace and line breaks
• Delete comments and metadata
• Clean empty containers and hidden elements
• Remove editor-generated namespaces
• Delete unused IDs and definitions

Path Optimization

• Simplify path commands and coordinates
• Convert basic shapes to paths
• Merge adjacent paths
• Remove paths beyond canvas

Style Optimization

• Compress color value representation
• Merge duplicate styles
• Inline styles to attributes
• Remove default values

Numeric Optimization

• Unify numeric precision
• Simplify transformation matrices
• Optimize coordinate representation

Structure Optimization

• Flatten invalid grouping
• Remove DOCTYPE declarations
• Sort attributes to improve compression ratio

Compression Results

Typical SVG files can achieve 30%-70% size reduction:

Original: 15,234 bytes
Optimized: 4,521 bytes
Saved: -70.33%

Use Cases

• Website icon and logo optimization
• Reduce web resource loading time
• Compress SVG icon libraries
• Clean redundant data from design software exports
• Remove redundant data from third-party SVGs

Notes

• Some optimizations may change SVG internal structure; test output results
• SVGs with animations or scripts require careful selection of optimization options
• To preserve specific IDs for CSS/JavaScript references, disable the "Clean IDs" option
• All processing is completed locally in the browser, ensuring file security
