mc-api Map Art Converter

mc-api Map Art Converter turns images into Minecraft map files or construction plans, and suits players who want either output or need to automate conversion through an API. Its range of output formats makes it useful for both map-item creators and builders, but the fixed palette and lack of service guarantees are meaningful constraints.

Overview

Upload a PNG, JPEG, or WebP image up to 8 MB and choose a map file or a building plan. Map files preserve transparency and use all four shades across 244 colours. Flat plans reach 61 colours, while staircase plans reach 183; those lower ranges make the plans useful for construction, but they do not match the map-file colour coverage. Palette control is fixed, so users cannot tailor colours to a particular collection of blocks.

For in-game use, place downloaded map_<n>.dat files in a world's data folder so the map item displays the picture. The service states that it is not affiliated with Mojang or Microsoft.

Key features

• Map and build outputs: Choose a map file or a block plan with placement guidance and a materials list. Schematic export adds a route for moving a design into a construction workflow.
• Two dithering options: Floyd–Steinberg dithering or no dithering gives users a choice about how image colours are rendered.
• API conversion: The API accepts raw image bytes and can return a .dat map file, PNG preview, or JSON block plan. A conversion returns one map file, or a ZIP when the map grid exceeds one map, which is useful for automated workflows involving larger images.
• Hosting and privacy: The provider says the application, database, and caches run on its own server infrastructure, with Cloudflare handling delivery and attack absorption. The privacy policy describes TLS/HTTPS connections and short-lived Redis-cached IP addresses for quotas and abuse protection.

Pricing

The Free service costs nothing. It has no trial period because the service is free of charge; API conversions consume one credit each. That makes it a practical option for occasional use or testing an API workflow without a subscription, but the service offers no availability or response-time guarantee.

Platforms

The converter is available on the web and through an API. That covers manual uploads as well as integrations that submit raw image bytes. The service does not promise data retention, so users who need guaranteed storage or dependable processing windows should choose a service with terms that meet those needs.

Who it's for

This is a good fit for Minecraft players who want map files with transparency, builders who need a placement guide and materials list, and developers who want to request conversions through an API. It is less suited to users who need palette customization or assured uptime and response times. The imprint names Leon Janz as the provider and gives an address in Appenweier, Germany; it invites users to contact the provider about issues.

Pros and cons

Pros

• Map files preserve transparency and cover four shades across 244 colours, giving map creators a broad output palette.
• Block plans include placement guidance and a materials list, with flat and staircase options for different building approaches.
• The API returns map files, previews, or JSON plans, and packages outputs as a ZIP when the grid spans multiple maps.

Cons

• Images are capped at 8 MB, limiting use with larger source files.
• The palette is fixed, and plan outputs top out at 61 colours for flat layouts or 183 for staircase layouts.
• Availability, response times, features, and data retention are not guaranteed, which makes the service a weaker choice for workflows that depend on continuity.
