How to Convert an Image to a Minecraft Schematic

A Minecraft schematic stores blocks and positions, so converting an image requires more than making it look pixelated. The image must become a fixed-size wall, every visible pixel must map to a real Java Edition block, and the exported structure must use a format that the target editor understands.

Start with a wall-sized source

Choose the finished block width before worrying about the source resolution. A 32- or 64-block wall works well for icons and simple character art; wider walls retain more detail but require many more materials. Crop unrelated background so the available concrete colors are spent on the subject.

Match the image to buildable blocks

Img2MC maps visible pixels to the sixteen concrete colors used by its wall workflow. Transparent pixels can become air. Compare no dithering for clean edges with the available dithering modes for gradients, then inspect the preview at the size you plan to build.

Export Sponge Schematic v3

After the preview and material totals look correct, continue to Build & export and download the .schem file. Img2MC writes a one-block-thick Java wall using namespaced block IDs in a GZip-compressed Sponge Schematic v3 container.

The download is intended for a compatible WorldEdit installation. It is not a native .litematic, Bedrock structure, command file, or map-art export.

Test the file before using it

Keep the PNG blueprint and CSV material list beside the schematic. Load the .schem in a disposable backup world, paste it into open space, and verify width, height, wall direction, colors, and transparent areas before moving it near an important build.
