Img2Num JavaScript

What is Img2Num?

Img2Num is a high-performance raster-to-vector conversion library that transforms images into SVGs. It is powered by WebAssembly (WASM) for speed, while providing easy-to-use JavaScript wrappers for integration into web or Node.js projects.

Features

• Fast raster vectorization with WASM backend.
• Typed array support: Works with Uint8Array, Uint8ClampedArray, and Int32Array.
• String outputs: Converts results directly into SVG strings.
• Worker-friendly: Supports offloading heavy computations to Web Workers.
• Zero dependencies: Pure WASM + JS with no external libraries required.
