Litematic Export Guide · Updated August 3, 2026
How to export Minecraft image art as a Litematic file.
A .litematic file is Litematica’s native schematic format. BlockArtLab generates the block-state palette, compressed NBT data, material geometry, size metadata, and wall or floor coordinates directly in the browser. The result can be loaded as a placement guide in Minecraft Java Edition with the Litematica mod.
1. Convert and review the image
Upload a PNG, JPG, or WebP, select the block dimensions, and choose a palette. Inspect both the preview and material list. Litematic export uses the same converted blocks shown in the 2D blueprint, so palette changes directly affect the schematic.
2. Choose the correct geometry
Wall art exports a structure sized width × height × 1. The image top maps to the highest Y coordinate. Map art exports width × 1 × depth, with image rows mapped along Z. Choosing the direction before export prevents a vertical mural from loading flat—or map art from standing upright.
3. Download the schematic
Select Export .litematic. The file is generated locally and downloaded without uploading the source image. BlockArtLab currently writes stable Java Edition 1.20.1 block data and uses blocks that remain present in later releases. Compatibility can still vary with mod and game versions, so retain the PNG and CSV as readable backups.
4. Load it with Litematica
- Install a compatible Litematica build and its required library for your Minecraft instance.
- Move the downloaded file into that instance’s schematics folder.
- Open Litematica’s schematic manager and load the file.
- Place the schematic in a creative test world and verify its orientation.
- Use the material list and placement overlay for the final build.
What the export contains
The file contains one named region, a block-state palette beginning with air, packed block-state indices, the structure dimensions, position data, total block count, timestamps, and the Minecraft data version. It is gzip-compressed NBT rather than a renamed image file.
Troubleshooting
If the file does not appear, confirm that its extension remains .litematic and that it is in the schematics folder for the correct Minecraft instance. If loading fails, test with a Litematica version compatible with the exported data version. Never assume renaming another schematic format changes its internal structure.
