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.
Edit and create single-stroke SVG fonts for pen plotters — draw glyphs with pen and pencil tools, trace images or TTFs, tune kerning, and export a plotter-ready SVG font. Runs entirely in your browser.
See how an SVG will look once plotted — drop it onto a photorealistic sheet of paper, pick a stock and pen width, and check the real-world size against a grid and rulers. Runs entirely in your browser.
Turn any photo into plotter-ready SVG line art with 40 algorithms — squiggles, stipples, hatching, flow fields and more — plus multi-pen color separation and physical output sizing. Runs entirely in your browser.
Stack non-destructive effects on any SVG — warp, repeat, hatch, shatter — with live preview, seeded randomness, plot stats and plotter-ready export. Runs entirely in your browser.
Rebuild any photo as a plotter-ready mosaic of hand-drawn doodles from the Google Quick Draw dataset, exported as a multi-pen SVG sized for real paper. Runs entirely in your browser.
