VTracer (via) VTracer is an open source library written in Rust for converting raster images (JPEG, PNG etc) to vector SVG.

This VTracer web app provides access to a WebAssembly compiled version of the library, with a UI that lets you open images, tweak the various options and download the resulting SVG.

UI elements include: logo, download options, and image processing controls for clustering, filtering, color precision, gradient step, and curve fitting.

I heard about this today on Twitter in a reply to my tweet demonstrating a much, much simpler Image to SVG tool I built with the help of Claude and the handy imagetracerjs library by András Jankovics.
