Thomas Steiner has released a tool named SVGcode. It’s a PWA to convert raster images to SVG vector graphics.
SVGcode is a Progressive Web App that lets you convert raster images like JPG, PNG, GIF, WebP, AVIF, etc. to vector graphics in SVG format. It uses the File System Access API, the Async Clipboard API, the File Handling API, and Window Controls Overlay customization.
Under the hood sits potrace — a tool for transforming bitmaps into vector graphics — which was translated to WebAssembly.
