mc-api Map Art Converter turns an image into a Minecraft map file or a block plan for building the picture in-game. The web tool accepts PNG, JPEG, and WebP images up to 8 MB. Map-file output preserves transparency and supports four shades across 244 colours. Block plans show where each block goes and include a materials list; flat plans reach 61 colours and staircase plans 183. Users can choose Floyd–Steinberg dithering or no dithering, though palette control is fixed. The API accepts raw image bytes and can return a .dat map file, a PNG preview, or a JSON block plan. A conversion returns one map file, or a ZIP if the map grid is larger than one map. Downloaded map_<n>.dat files go in a world's data folder for the map item to display the picture. The service is free of charge, and each API conversion uses one credit. Its provider says availability, response times, and data retention are not guaranteed; the site is not affiliated with Mojang or Microsoft.
