What Image to Minecraft Map is

Image to Minecraft Map is a free web app for converting images into Minecraft NBT map .dat files to display in Minecraft. It can process multiple image files at once through drag and drop, and download the results as separate .dat files or together in a .zip file. To make a larger image, split it across a grid of up to 10 by 10 maps. Before conversion, choose Fit, Fill (Crop), or Stretch resizing, set a background color, or adjust the transparency threshold. Color matching options include CompuPhase, Euclidean, DeltaE 1976, DeltaE 2000, and CMC 1984, with Floyd-Steinberg dithering available. The app runs in a browser. Its settings list Java Edition palettes from versions 1.8.1 through 1.17 or newer and recommend matching the palette to the target game version; mismatches are not guaranteed to work. The resize quality setting works in Chrome and Edge, but has no effect in Firefox or Safari. Bedrock Edition support is listed as a future improvement. To use a converted image in-game, replace a map .dat file in the Minecraft world's data directory with the downloaded file. The project is licensed under MIT and states it is not affiliated with Mojang or Microsoft.
