QUICK ANSWER
Is it possible to convert BBMODEL to GLB?
Yes - BBMODEL converts to GLB.

You can do it right here with our free converter - no sign-up, and your file is deleted right after.

Open the project in Blockbench, then use File > Export > Export as glTF and choose the binary .glb option. The geometry and textures come across cleanly, but quads are triangulated and per-face vertices are split, so the mesh is heavier than the original.

Why convert BBMODEL to GLB?

.bbmodel is Blockbench's own editable project file, while .glb is a self-contained binary 3D asset that bundles mesh, materials and textures into one file for game engines, AR/VR and web viewers. People export to .glb when they need a portable, ready-to-render model that Unity, Godot, three.js or Windows 3D Viewer can load without extra texture files.

How to convert BBMODEL to GLB

Blockbench (File > Export as glTF) OPEN-SOURCE

Open the .bbmodel, then choose File > Export > Export as glTF and pick the binary .glb option in the dialog. Blockbench embeds the textures into the single .glb file.

Blender (import glTF, re-export) FREE

If you first export a plain .gltf/.obj from Blockbench and import it into Blender, you can then File > Export > glTF 2.0 and choose the .glb container for more control over compression and materials.

About these formats

.BBMODEL Blockbench 3D Model Project

A .bbmodel file is the native project file of Blockbench, a free 3D model editor used mainly for Minecraft and other low-poly game models. It is a JSON text file that stores the geometry,…

.GLB glTF 2.0 Binary (3D model)

A GLB file is a 3D model in glTF 2.0 Binary format - one self-contained file with geometry, materials, textures and animation. On Windows open it free with Microsoft 3D Viewer; on macOS…

Quality & what to watch

  • Blockbench triangulates all quads and stops sharing vertices between faces, so the exported .glb has more vertices and triangles than the tidy box model you edited.
  • .glb is an output format - you cannot re-open it in Blockbench and keep the editable box/cube structure, so always keep the original .bbmodel.
  • Minecraft-style animations only survive if the source used a format that supports them; static block/item models export as geometry with no motion.

Frequently asked questions

What is the difference between glTF and GLB from Blockbench?
Both come from the same File > Export as glTF menu. .gltf is JSON plus separate texture files, while .glb packs everything into one binary file.
Are textures included in the .glb file?
Yes. Blockbench embeds the model's texture into the .glb, so it is a single portable file with no external image needed.
Why does my model have more triangles after export?
Blockbench converts quads to triangles and splits vertices per face during glTF export, which increases the polygon and vertex count.
Can I convert GLB back to bbmodel?
Not cleanly. .glb loses the editable cube hierarchy, so keep your .bbmodel project as the master copy.
