Minecraft Map Art Generator by Joshua Dobson

About

Minecraft Map Art Generator by Joshua Dobson turns an image into a layout for Minecraft map art by matching its pixels to available block colours. The tool uses CIELAB colour space for colour matching and supports a 128×128 output, the standard size for one map item. Larger images can be divided into 2×2, 3×3, or 4×4 grids; each section can be downloaded as its own 128×128 PNG. Floyd-Steinberg dithering is available for gradients and complex images. Exports include PNG, JSON, CSV, and .litematic files, and a generated grid can be downloaded as a ZIP. The tool also calculates block counts and exports material lists in CSV or JSON to help plan building supplies. Processing happens in the browser, and the maker says uploaded images are not sent to a server. Its privacy policy says there are no cookies, analytics, or tracking and no passive personal-data collection. The maker cautions that height-based shading in Minecraft maps means colour matching is only a best-effort guide. The web tool is free to use.

Who it is for

It suits Minecraft builders who want to convert an image into a map-art layout and plan the blocks needed. It is especially useful when the image needs multiple maps or material-list exports.
