Convert a 3D Model to GLB, the Single-File glTF Format

Convert OBJ, STL, PLY, glTF, Collada or 3MF into one binary glTF file with materials and hierarchy intact, using the three.js loader suite in your tab.

  • Reads OBJ, STL, PLY, glTF, GLB, Collada (.dae) and 3MF and writes a single self-contained .glb
  • Node hierarchy, object names and material definitions survive the round trip when the source format carries them
  • PLY vertex colours are detected and kept, so scan data arrives coloured rather than grey
  • Geometry is counted before export and an empty or geometry-free scene is reported instead of downloading a 20-byte file

Direct Overview & Quick Answer

GLB is the binary packaging of glTF that keeps mesh, scene hierarchy, PBR materials and textures inside one file, and this page re-serialises OBJ, STL, PLY, glTF, Collada or 3MF input into it using the three.js loader and exporter suite.

How to Use the Free Online 3D Model to GLB Studio in 4 Steps

Simple 4-step walkthrough for fast, secure processing

Step 1

Pick a model in a supported format

OBJ, STL, PLY, glTF, GLB, Collada .dae or 3MF. Export to one of those first if your model is FBX, STEP or a native application file.

Step 2

Drop it onto the page

The three.js loader for that format is fetched on demand and the file is parsed into a scene graph inside the tab.

Step 3

Let the scene be re-serialised as GLB

Triangle count is checked first, then the scene graph, materials and any embedded textures are written into one binary glTF buffer.

Step 4

Download and load it in a viewer

Open the .glb in model-viewer, Babylon Sandbox, Windows 3D Viewer or Blender to confirm the materials and orientation are what you expected.

Frequently Asked Questions About 3D Model to GLB

Everything you need to know about 3D Model to GLB on editpdfkit.com

Six: OBJ, STL, PLY, glTF and GLB, Collada (.dae), and 3MF. Those are the formats three.js ships reliable parsers for. FBX, 3DS, AMF, STEP, IGES, SolidWorks parts and Blender's own .blend are not readable here — they need either a licensed SDK or a full kernel. Blender exports GLB directly, and for STEP or IGES, FreeCAD will convert to a mesh format first.
