How do I import the downloaded world?

Open the .mcworld file and Bedrock imports it, or unzip it into games/com.mojang/minecraftWorlds manually.

Is there a size limit?

No structure-block cap applies to a world, so builds much larger than 64 blocks work. Voxelization time and browser memory are the practical constraints.

My .gltf will not open in the converter.

It most likely references external .bin or image files. Re-export from your 3D tool as embedded glTF or as .glb.

Can I edit the world after importing it?

Yes. It is a standard Bedrock save, so you can open it in creative and change anything in it.

Convert .gltf to .mcworld

Explore a glTF model at full scale in Minecraft. Bloxelizer voxelizes the .gltf in your browser and packages the blocks as a .mcworld you can open to import into Bedrock.

The .gltf and .mcworld formats

A .gltf file is JSON glTF — a scene of meshes and materials whose binary data may be embedded or split into side files. A .mcworld is a complete Bedrock Edition world: a zipped save with a LevelDB block database and a level.dat. The conversion voxelizes the glTF mesh into Minecraft blocks, maps them to Bedrock, and writes them into a fresh world that opens as its own save.

How to convert .gltf to .mcworld

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

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

Select .mcworld as the export format, download the world, and open it to import it into Minecraft Bedrock.

When to use this conversion

Best for large models — buildings, terrain, sculptures — that you want to walk through in game rather than paste into an existing build.

Compatibility notes

Use an embedded .gltf, since external .bin and texture references are not resolved; .glb is the safer export if in doubt. The world is generated flat around the model, and very large build sizes are limited mainly by browser memory.
