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

Upload one or more SVG files
Tool automatically performs optimization processing
View optimization results including file size changes and savings percentage
Click the code area to copy optimized SVG code
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
