About this tool
This knitting and crochet chart generator runs entirely in your browser. Your image is reduced to a chosen number of colours with median-cut quantisation, then every stitch is matched to the closest palette colour — or dithered with Floyd–Steinberg if you want softer gradients.
The result is a chart you can work from directly: one symbol per colour, a legend with stitch counts and coverage, and a downloadable PNG sheet with the grid and legend together. Nothing is uploaded, so your photos never leave your device.
