Minecraft Map Art Generator by Joshua Dobson is a free web tool that converts an image into a Minecraft map art layout. It maps image pixels to the closest available block colour using CIELAB colour matching. A single-map layout is 128×128, the size of one Minecraft map item. For larger designs, the tool can divide an image into 2×2, 3×3, or 4×4 grids, with each section downloadable as a separate 128×128 PNG. Floyd-Steinberg dithering is available to improve colour accuracy in gradients and complex images. Downloads include PNG, JSON, CSV, and .litematic formats; generated grids can also be downloaded as ZIP files. The tool calculates block counts and can export a materials list as CSV or JSON to help plan what is needed. Processing takes place in the browser, and the maker says uploaded images are not sent to a server. The privacy policy says there are no cookies, analytics, or tracking, and no passive collection of personal data. Voluntary feedback may include an optional email address and is handled by Web3Forms. The maker cautions that height-based map shading makes colour matching a best-effort guide.
Who it is for
This tool suits Minecraft players planning map art from an image, especially when they need a block count or layout split across multiple maps. It runs in a web browser and offers several export formats.
What is good
- Creates standard 128×128 single-map layouts.
- Can split designs across 2×2, 3×3, or 4×4 grids.
- Provides block counts and materials-list exports.
- Processes images in the browser.
- Offers PNG, JSON, CSV, and .litematic exports.
What to know first
- Colour matching is only a best-effort guide because maps shade by height.
- GitHub Pages may collect standard server access logs.
- Voluntary feedback may include an email address.
Verdict
The tool turns an image into a map layout and provides grid, export, and material-planning options. Its colour match is a guide rather than an exact result because Minecraft maps apply height-based shading.
