Vectorize

Three paths

1. Recraft /vectorize (hosted, highest quality)

Input: any raster. Output: clean SVG, typically 20–100 paths for a mark, 200–500 for an illustration. Commercial tier only.

const svg = await recraft.vectorize({ image: pngBuffer });

2. vtracer (local, multi-color polygon)

• Rust binary; npm install vtracer for the Node wrapper.
• Modes: polygon (recommended for logos), spline (smoother curves), pixel (blocky).
• Color count controlled upstream via K-means quantization before vectorization.
