DrawingBotV3 DrawingBotV3 (Free)
Free, open-source software that turns photos into plottable line art — sketch, stipple and hatch styles that export clean SVGs for your plotter.
Our verdict
The best free tool for turning a photo into genuine plotter line art. If you want to plot images without messy auto-tracing, start here.

What we like
- Turns photos into real line art — not flat auto-traced blobs
- Many path styles: sketchy lines, stipple, crosshatch, spiral
- Exports clean SVGs ready for vpype and your plotter
- Free, open source, cross-platform
What to watch
- Java app — needs a runtime installed
- Lots of parameters; takes experimentation to master
- Best results still need a pass through vpype to optimize
“How do I plot a photo?” is one of the most common plotter questions, and the honest answer is: not by tracing it into filled shapes. You convert it into line art — and DrawingBotV3 is the best free tool for exactly that.
What it does
DrawingBotV3 takes a raster image and redraws it as plottable paths in a range of styles — sketchy contour lines, stipple dots, crosshatching, spirals, and more. Instead of a flat vectorized blob, you get art built from strokes a pen can actually draw, with a genuinely hand-rendered quality.
The workflow
- Load your photo and pick a path style (sketch and stipple are great starting points)
- Tune density, line count, and detail to taste
- Export as SVG
- Run it through vpype to merge and reorder for efficient plotting
- Plot it
The export-then-optimize step matters — DrawingBotV3 produces many separate paths, and vpype turns that into an efficient plot.
Where it fits
This is the missing piece for anyone who wants to plot portraits, landscapes, or any source image. It pairs naturally with the rest of the free stack — Inkscape, vpype, and code tools — and costs nothing. If you’ve been frustrated trying to plot photos, DrawingBotV3 is the tool that finally makes it work.
