A lightweight Node‑CLI utility that converts any RGBA image into a signed distance field (SDF) by treating pixels with alpha > 128 or any RGB channel > 128 as solid. It’s aimed at developers, game artists, and UI designers who need SDF textures for crisp scaling or shader effects, and can also be used programmatically via its npm package.
