Free, browser-based sketch to SVG converter. Turn a scanned pencil or pen sketch into clean, editable vector paths. No upload, no watermark, 100% private.
Quantize colors, blur, and boost contrast for clean cartoon-style vectors.
For illustrators, students, and product designers who sketched an idea on paper and want to vectorize those pencil or ink lines into editable, scalable SVG paths.
A photographed or scanned sketch carries paper texture, uneven lighting, and pencil grain that a basic tracer turns into a noisy mess — this tool is tuned to clean that up, and it works in your browser so your sketch is never uploaded. We default numColors to 4 to flatten paper shading and lighting gradients into clean tonal regions, then lean on a raised pathomit to wipe out the speckle from paper grain and scanner noise. The threshold separates your pencil and ink lines from the off-white page, so faint paper tone falls away while your linework survives. Tight ltres and qtres keep the natural flow of hand-drawn curves intact. The result is an editable SVG you can refine, recolor, or scale to print size. For a clean ink sketch, drop numColors to 2 for pure linework; for a shaded pencil sketch, keep it higher to retain tone, or enable Cartoon Mode for bold shapes.
