Image to Minecraft Blocks

The tool accepts an input image and outputs a Minecraft-ready block representation. It reduces the image to a grid of blocks by mapping colors to a selected palette, optionally applying dithering to preserve detail at low resolutions. Users can target a specific width and height in blocks, choose either vanilla or expanded block palettes, and decide how transparency is treated. The result is a data-friendly map suitable for in-game construction or schematic export.
Conceptually, the process consists of color quantization, nearest-block color assignment, and optional error diffusion. Color distance is computed in a perceptual color space to improve fidelity. The algorithm can downscale or upsample input images to fit the requested grid, with edge-preserving options to maintain outline integrity without creating artifacts.
Audience and use cases: builders, texture artists, and mapmakers use the tool to accelerate visual planning, turn reference art into block-form, or generate automation-friendly data for Minecraft projects. It supports batch processing and export in formats compatible with common tools, such as MCEdit-compatible schematics or JSON block maps, enabling integration into pipelines.
Unique value: palette flexibility, perceptual mapping, and transparent handling, combined with output formats and optional dithering, allow a higher fidelity block rendition from a wide range of inputs. This reduces manual palette tweaking and speeds up iterative design.
