dotart

Turn any image into retro dithered pixel art — the dotted, halftone look of old print and early displays. Drop in a photo and dotart re-renders it with a reduced palette and classic dithering, all in your browser. Nothing is uploaded; the conversion runs locally via WebAssembly.

Try it

Open the web version — no install, works on desktop and mobile:

How it works

  • Median-cut palette reduces the image to a small, coherent set of colors.
  • Floyd–Steinberg and Bayer dithering trade solid tones for patterns of dots, so gradients survive even with just a handful of colors.
  • Compiled from a pure Go core to WebAssembly, so the same engine powers the CLI and the site.

Command-line version
