Classic bitmap tracing lives in desktop software such as Illustrator, where both the learning curve and the subscription add up. The PolySVG self-developed model performs colour quantisation, contour tracing and Bézier fitting automatically: open the page and the conversion runs in milliseconds, while line-art and edge modes extract clean strokes.
The complete vector workflow
Turn a bitmap into a vector with Image to SVG, then refine it in the online editor — remove the background, touch it up with the brush, erase with the eraser, adjust the colours — and export SVG or high-resolution PNG in one click.
