Minecraft Map Art Generator
Convert any image into a Minecraft map art layout using accurate perceptual colour matching. Upload a photo or design, crop it to a square, and the tool instantly maps every pixel to the closest available Minecraft block colour.
Features
Supports 128×128 single map output — the standard size for one Minecraft map item. Multi-map grid export lets you split a large image across a 2×2, 3×3, or 4×4 grid of maps for large-scale builds. Floyd-Steinberg dithering improves colour accuracy in gradients and complex images. Download your result as a PNG, or export block counts as CSV or JSON to plan your materials.
How it works
The tool uses CIELAB colour space matching to find the closest Minecraft block for each pixel — more accurate than simple RGB comparison. All processing happens in your browser, no data is uploaded to any server.
Free to use
This Minecraft map art converter is completely free. If you find it useful, consider supporting development on Ko-fi.
