Free Image to GLB Converter

Why GLB?

GLB is the binary version of glTF, the open "JPEG of 3D" format. One GLB file holds the mesh, the materials and the textures, so there are no missing texture files when you move it around. Web viewers such as three.js and model-viewer, AR on phones, Blender, Godot, Unity (with glTFast) and Unreal all read it. This tool creates a GLB straight from a picture.

How to convert an image to GLB

1. Upload a JPG, PNG or WEBP of a single object on a plain background.
2. Choose a style and polygon count. For the web and AR, 10,000 to 30,000 triangles keeps files light; for close-up renders go higher.
3. Generate, then press Texture so the GLB carries colors.
4. Download GLB. OBJ (zipped with its texture) and STL are there too if you need them.

Using the GLB file

• On a website: drop it into a three.js scene or a <model-viewer> tag.
• In Blender: File, Import, glTF 2.0. Materials and textures come in automatically.
• In Godot: copy the file into your project; Godot imports GLB natively.
• In Unity: install the glTFast package, then drag the file into Assets.

More detail on formats is in STL vs GLB vs OBJ, and engine-specific steps are in using AI 3D models in game engines.

Getting a better GLB

• Use a sharp, evenly lit photo; the texture is painted from it.
• Choose "Texture: High" for sharper colors on close-up models.
• Keep the polygon count as low as looks good: smaller files load faster on phones.
