VTracer is the open-source Rust library that powers ConvertSVG. Here's what makes it special.
How It Works
VTracer converts raster images to vectors in three steps: color clustering, contour extraction, and curve fitting. It processes each color region independently, traces its boundary, and fits smooth bezier curves to the resulting paths.
Key Advantages
- O(n) complexity — conversion time scales linearly with image size
- WebAssembly — runs entirely in your browser, no server uploads
- High precision — supports up to 8-bit color precision for rich detail
- Open source — MIT licensed, auditable, and community-maintained
