How do I add the world to Minecraft?

Unzip the download and put the world folder in .minecraft/saves. It then appears in your singleplayer world list.

Why does my .gltf fail to open?

It most likely points at external .bin or texture files. Re-export it as embedded glTF or as .glb so everything is in one file.

Is there a size limit?

No structure-block or paste limit applies to a world, so builds much larger than 48 blocks work. Browser memory and voxelization time are the practical limits.

Can I edit the build after importing?

Yes. It is a standard Java save, so creative mode and world editors both work on it.

The .gltf and Java world formats

A .gltf file is JSON glTF: a scene graph of meshes and materials whose binary data may be embedded or split into side files. A Minecraft Java world is a save folder of region (.mca) files plus a level.dat. The conversion voxelizes the glTF mesh into blocks and writes them into a fresh world folder, downloaded as a .zip you unzip into your saves.

How to convert .gltf to Java world

Upload a self-contained .gltf file in the converter below.

Choose the build size, rotation, and block palette in the preview panel, then apply.

Keep the Java world format selected, download the .zip, and unzip it into your saves folder.

When to use this conversion

Best for large models — buildings, terrain, sculptures — that you want to walk through rather than paste into an existing build or squeeze into a structure block.

Compatibility notes

Supply an embedded .gltf, since external .bin and texture references are not resolved; .glb is the safer export if you are unsure. Load the world in a Minecraft version that supports the blocks your palette chose.
