Tools
Free, interactive tools for pen-plotter and drawing-robot enthusiasts — each one runs right here in your browser. Nothing to install, nothing uploaded to a server. Looking for third-party software instead? Browse the tools & generators directory.
Upload an SVG, position a crop region, and perform a real geometric crop — paths are actually cut at the boundary, ideal for pen-plotter line art. Runs entirely in your browser.
Generate mesmerizing radial designs from nested, rotated polygons — drive them with math formulas, pick from 20 curve styles, and download a plotter-ready SVG. Runs entirely in your browser.
Trace evenly-spaced streamlines through a vector field defined by two math formulas — randomize your way to endless flowing designs and download a plotter-ready SVG. Runs entirely in your browser.
Merge, sort and simplify SVG paths for faster plotting with vpype-style optimizations — compare before/after with a wipe slider. Runs entirely in your browser.
Convert SVG artwork into HPGL for vintage pen plotters — pick your plotter model and paper size, fit the art to the page, and download a ready-to-plot file. Runs entirely in your browser.
Type text in single-line plotter fonts (Hershey, EMS and more), place it over your own SVG with drag, rotate and scale, and export stroke-only paths ready to plot. Runs entirely in your browser.
