# 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. ```ts 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. ``` pipeline: raster 1024² → BiRefNet matte (alpha the background) → K-means LAB 6-color palette → vtracer --mode polygon --filter-speckle 4 --color-precision 6 → SVGO (conservative preset) ``` ### 3. `potrace` (local, 1-bit) - Classical Stan Ford vectorizer; binary output only (no color). - Best for: icon packs (single-color), typography work, line art. - Multi-color workaround: separate each color into its own 1-bit layer, vectorize each, stack SVG `<g>`s. ``` pipeline: raster 1024² → BiRefNet matte → per-color mask (binary threshold per palette entry) → potrace per mask → <g> wrapper → combine into single SVG → SVGO ``` ## Choosing the path | Use case | Path | |---|---| | Budget available, one-shot quality | Recraft vectorize | | Multi-color logo, local | vtracer (polygon mode) | | Single-color icon pack | potrace | | Photorealistic illustration → vector | don't — keep as PNG/WebP.
