Minecraft Map Art Generator by Joshua Dobson

Overview

Minecraft Map Art Generator by Joshua Dobson is a free web tool that turns an image into a Minecraft map art layout. It matches pixels to nearby block colours using CIELAB colour space. A single layout is 128×128, the size of one Minecraft map item; larger images can be divided into 2×2, 3×3, or 4×4 grids, with each segment available as a separate 128×128 PNG. Floyd-Steinberg dithering can help with gradients and complex images. Exports include PNG, JSON, CSV, and .litematic files, while generated grids can be downloaded as ZIPs. The tool calculates block counts and can export material lists as CSV or JSON. Image processing happens in the browser, and the maker says uploaded images are not sent to a server. The privacy policy says there are no cookies, analytics, tracking, or passive collection of personal data. Voluntary feedback may include a rating, message, feedback type, and optional email; GitHub Pages may collect standard access logs. The maker notes that height-based shading on Minecraft maps makes colour matching a best-effort guide.
