GLB is the binary version of glTF 2.0, the open format maintained by the Khronos Group and often called the JPEG of 3D. It packs the mesh, PBR materials and texture images into one file, uses metres as its unit, and loads natively in web viewers, Android Scene Viewer, Blender, Windows 3D Viewer and most engine pipelines.

That makes it the right download when color matters: product previews, AR try-ons, game props, or a full-color model you will later turn into a multi-color print. Full-color generation and GLB export are part of PrintPal Pro. The model in the viewer below is a real PrintPal GLB, reduced for the web.

## How to convert an image to GLB

1. **Upload an image.** Even lighting and a plain background give the cleanest texture.
2. **Sign in and turn on Full color.** Full color and GLB export are Pro features.
3. **Generate.** Spin the textured preview to check the back.
4. **Download GLB.** One self-contained file.

## Things to know

- **Lighting gets baked in:** Shadows and reflections in the image are painted onto the texture. Diffuse light gives a cleaner, more reusable model.
- **Metres, not millimetres:** glTF is in metres, which suits engines and AR. Slicers expect millimetres, so convert before printing.
- **Printing a GLB:** Most slicers do not open GLB. Use the free [AMS converter](https://printpal.io/tools/ams-converter) for a color 3MF, or download STL.
- **iPhone AR needs USDZ:** GLB covers Android and the web; export USDZ from Blender or Reality Converter for AR Quick Look.

## GLB at a glance (Binary glTF 2.0)

- **Stores:** Mesh, PBR materials and textures in one binary file
- **Color:** Yes, full textures
- **Units:** Metres
- **Size (our 1M-triangle test):** 40.5 MB with textures, 403 KB optimized for the web
- **Opens in:** Blender, three.js and other web viewers, Windows 3D Viewer, Android Scene Viewer, Unity and Unreal importers
- **PrintPal plan:** Pro and Studio

### After you download the GLB

- Preview it in the free [3D model viewer](https://printpal.io/tools/3d-model-viewer) or drag it into Blender (File, Import, glTF 2.0).
- glTF works in metres: a height of 0.08 means 8 cm. Scale it in your engine or scene.
- For a website, compress the mesh with meshopt or Draco and resize textures to 1024 px. The models on this page went from about 40 MB to under 450 KB that way.
- To print it in color, open the GLB in the free [AMS converter](https://printpal.io/tools/ams-converter), reduce it to 2 to 8 filament colors and download a 3MF.
- iPhone AR Quick Look wants USDZ; export one from Blender or Apple's Reality Converter.

## Same model, every format (measured)

Same 998,810-triangle knight exported with trimesh; the GLB is the download as it came from PrintPal. The 3MF holds geometry only; a painted multi-color 3MF adds a little for the color data.

| Format | File size | Color | Units | Typical use |
|---|---|---|---|---|
| STL (binary) | 49.9 MB | No | None (slicers assume mm) | Any slicer |
| STL (ASCII) | 303 MB | No | None | Legacy CAD; avoid |
| OBJ + MTL + texture | 84.9 MB | Texture or vertex colors | None | Blender, sculpting |
| GLB (with textures) | 40.5 MB | Yes, PBR textures | Metres | Web, AR, games |
| 3MF (zipped) | 21.0 MB | Yes, per triangle | Millimetres | Bambu Studio, OrcaSlicer, PrusaSlicer |
| PLY (binary) | 27.3 MB | Vertex colors | None | Scans, point clouds |

## Real example

The cosplay helmet model shown on the page was generated by PrintPal from helmet.png (1024 px). Raw output: 999,490 triangles, one watertight body with consistent winding. Web preview: 59,958 triangles, 378 KB GLB.

## FAQ

### What is the difference between GLB and glTF?

Both are glTF 2.0. A .gltf is JSON that points to separate binary and image files; a .glb packs all of them into one binary file.

### Is GLB export free?

GLB and full-color generation are on Pro. The Free plan exports STL and OBJ.

### Can I 3D print a GLB?

Not directly in most slicers. Convert it to a multi-color 3MF with the free AMS converter, or download STL from the same generation.

### Does it work with three.js and model-viewer?

Yes. GLB is their native format. The viewer on this page is three.js loading a PrintPal GLB.

### Which PBR textures are included?

Our example GLBs carry a base-color texture and a metallic-roughness texture, which every glTF viewer reads automatically.

### How long does a conversion take?

Draft quality usually finishes in 30 to 60 seconds. Refined and Production take longer because they build more detail, and Pro generations run on a priority queue.

### Can I sell prints of the models I make?

Yes, on Pro and Studio, which include commercial rights for prints and digital files. The Free plan is for personal use. You also need the rights to the image you upload, so stick to your own photos and artwork or images you have permission to use.
