svgoo is a cross-platform SVG optimization tool that embeds the popular svgo JavaScript optimizer in a single Rust binary. No Node.js required!

# Install from source (releases coming soon)
git clone https://github.com/twardoch/svgoo.git
cd svgoo
npm run build && cargo build --release

# Optimize a single SVG file
./target/release/svgoo input.svg -o output.svg

# Process multiple files
./target/release/svgoo *.svg

# Use with pipes
cat input.svg | ./target/release/svgoo > output.svg

Download the latest release for your platform:

macOS (Intel):

curl -L https://github.com/twardoch/svgoo/releases/download/v1.2.0/svgoo-v1.2.0-macos-x86_64 -o svgoo
chmod +x svgoo
./svgoo --version

Coming Soon:

• macOS (Apple Silicon)
• Linux (x86_64)
• Windows (x86_64)

Prerequisites:

• Rust (latest stable)
• Node.js (for building JavaScript bundle)

git clone https://github.com/twardoch/svgoo.git
cd svgoo
npm install
npm run build
cargo build --release

The binary will be available at ./target/release/svgoo.

svgoo [OPTIONS] [INPUT_FILES...]

# Basic optimization
svgoo input.svg -o output.svg

# With pretty formatting
svgoo --pretty input.svg -o output.svg

# To stdout
svgoo input.svg

# Process multiple files (creates .min.svg versions)
svgoo file1.svg file2.svg file3.svg

# Process all SVG files in directory
svgoo *.svg

# With custom output directory (via shell)
for file in *.svg; do
  svgoo "$file" -o "optimized_${file}"
done

# Standard Unix pipe
cat input.svg | svgoo > output.svg

# With other tools
curl -s https://example.com/icon.svg | svgoo | gzip > icon.svg.gz

# Process from web
wget -qO- https://example.com/icon.svg | svgoo -o icon.svg

# Use custom configuration (coming in v2.0)
svgoo --config my-svgo.config.json input.svg

• ✅ Single Binary: No Node.js or dependencies required
• ✅ Cross-Platform: Works on macOS, Linux, and Windows
• ✅ Fast: Basic SVG optimizations in ~100ms
• ✅ Compatible: Produces similar output to svgo
• ✅ Thoroughly Tested: 89 tests across all components and platforms
• ✅ Multiple Files: Process multiple SVG files at once

• Remove comments and metadata
• Remove unnecessary whitespace
• Clean up attributes
• Normalize formatting
• Remove empty elements (basic)

• 🔄 Full svgo plugin system compatibility
• 🔄 Custom configuration files
• 🔄 Performance optimizations
• 🔄 Python and C++ bindings
• 🔄 Advanced CLI features

Note: svgoo prioritizes convenience and portability over raw speed.

svgoo is designed as a drop-in replacement for basic svgo usage:

# Instead of this (svgo)
npx svgo input.svg -o output.svg

# Use this (svgoo)
svgoo input.svg -o output.svg

✅ What works the same:

• Basic CLI interface (input.svg -o output.svg)
• Standard optimizations (comments, whitespace, etc.)
• File input/output handling
• Error handling and exit codes

⚠️ Current limitations:

• No plugin configuration yet (uses sensible defaults)
• Performance ~3-5x slower than native svgo
• Limited to built-in optimizations

❌ Not supported yet:

• Custom plugin loading
• Advanced configuration options
• Some edge-case optimizations

# Make sure the binary is in your PATH or use full path
./target/release/svgoo input.svg

# Or copy to a directory in PATH
cp target/release/svgoo /usr/local/bin/

# Ensure JavaScript bundle is built first
npm run build

# Clean and rebuild
cargo clean && cargo build --release

# Check Rust version
rustc --version  # Should be 1.70+

# Rebuild the JavaScript bundle
npm install
npm run build

# Check bundle was created
ls -la js-dist/svgoo-embedded.js

• svgoo currently applies basic optimizations only
• For advanced optimizations, use native svgo until v2.0
• File an issue if output differs significantly from expected

1. Check existing issues: GitHub Issues
2. Create new issue: Include input SVG, command used, and expected vs actual output
3. Discussions: For questions and feature requests

If svgoo is too slow for your use case:

• Use native svgo for large-scale processing
• Process files in parallel: ls *.svg | xargs -P 4 -I {} svgoo {}
• Consider using release builds: cargo build --release

svgoo embeds the svgo JavaScript optimizer using QuickJS runtime:

Input SVG → Rust CLI → QuickJS Runtime → svgo.js → Optimized SVG

This approach provides:

• Single binary: No external dependencies
• Compatibility: Same optimization logic as svgo
• Reliability: Rust's memory safety + JavaScript's flexibility
