How image to vector conversion works
Vectorization — also called image tracing — converts pixel images into shapes described by math: paths, curves and fills. The payoff is scale-independence. A vector graphic is as sharp at billboard size as it is as a favicon, can be edited shape-by-shape in any design tool, and is what cutting machines, plotters, engravers and print shops keep asking you for.
This vectorizer accepts PNG, JPG, WEBP, BMP, GIF, HEIC and PDF, and outputs SVG (the universal vector standard) and DXF (for CNC and laser software). Everything runs inside your browser: the tracing engine loads once, and from then on your files are processed on your own hardware. No upload also means no waiting on a server queue — a mid-size logo traces in well under a second on a normal laptop.
The four presets map to the four kinds of images people actually vectorize. “Logo” for flat-color artwork. “Silhouette” for anything destined for a cutting machine or stencil. “Detailed” for complex illustrations. “Photo” for the posterized art style. Every setting change can be re-applied to already-dropped files with one click, and the side-by-side preview with zoom lets you inspect edges before committing.
What tracing cannot do — and no honest tool will promise — is exceed the information in your source. Sharp, reasonably sized input produces professional results; a tiny blurry thumbnail produces a soft approximation. When you have a choice of source files, pick the biggest, cleanest one.
