Convert glTF Binary (GLB) to OBJ, STL, PDF (Free)
Also opens DWG, DXF, STEP, IGES, IFC, SKP, STL, OBJ, GLB, FBX, 3DM and other 3D/CAD files. Drop any file on the viewer.
No upload, no signup, no software to install

Why Convert glTF Binary (GLB) Files?
Game developers, AR/VR builders, web 3D engineers, e-commerce product visualization teams (Amazon, Shopify, etc.), and anyone delivering 3D over the open web. Most modern asset pipelines export GLB as the final hand-off.
Converting to a more widely supported format means your model can open in any 3D tool, slicer, web viewer, or AR app — without asking the recipient to install specialized software.
How to Convert a glTF Binary (GLB) File
- 1
Open your glTF Binary (GLB) file
Click "Open a glTF Binary (GLB) File" above, or drag and drop your .glb file onto the converter.
- 2
Choose an output format
Click the "Export" button in the toolbar and select OBJ, STL, PDF.
- 3
Download the converted file
Your file downloads instantly. Everything runs in your browser — nothing is uploaded.
Output Formats
glTF Binary (GLB) to OBJ (Wavefront)
One of the most universally supported 3D formats. Import into 3ds Max, Maya, Rhino, Cinema 4D, MeshLab, or virtually any 3D application.
glTF Binary (GLB) to STL (Stereolithography)
The standard for 3D printing. Upload directly to your slicer (Cura, PrusaSlicer, Bambu Studio) or a 3D printing service. Also used for CNC machining and FEA simulation.
glTF Binary (GLB) to PDF (Snapshot)
Export the current camera view as a one-page PDF with header and footer captions — ideal for presentations, submittals, and email handoffs.
Compatibility & Format Notes
Full support for glTF 2.0 GLB, including PBR materials (MetalRoughness), textures, vertex colors, multiple UV channels, skeletal animation, and the common KHR extensions (transmission, IOR, clearcoat, emissive, volume).
Looking for the JSON-based glTF form? See the glTF viewer page — same engine, same features.
Your Files Stay on Your Computer
Both parsing and conversion run entirely in your browser. The exported files are generated locally and downloaded directly to your device — nothing is uploaded to any server.
Frequently Asked Questions
▶How do I play animations and inspect a pose?
Open Animation in the toolbar when the model has clips or morph targets. Select a clip and use the timeline to inspect a pose. Playback starts automatically unless reduced motion is enabled or a shared link is paused. GLB export preserves the rig and clips; other model exports save the current pose.
▶What’s the difference between GLB and glTF?
GLB is a single binary file containing everything (geometry, textures, materials). glTF is the JSON form — a .gltf text file that references external .bin and image files. Same data, different packaging. GLB is preferred for distribution because it’s self-contained.
▶Does the viewer render PBR materials correctly?
Yes. PBR materials, including the common KHR extensions (transmission, IOR, clearcoat, emissive, volume) are rendered via three.js’s MeshPhysicalMaterial — the same renderer that powers Google’s <model-viewer>.
▶Can I convert GLB to STL or OBJ?
Yes. Click Export in the toolbar and choose STL (3D printing), OBJ (Wavefront), or PDF (current-view snapshot).
▶Is this GLB viewer really free?
Yes, completely free. No signup, no watermarks, no file size limits on the viewer (the optional share-link feature has a 100 MB upload cap). Built by Innerscene as a tool for architects, engineers, and designers.
▶Are my files uploaded to a server?
No. All parsing, rendering, and conversion runs in your browser: nothing is uploaded, stored, or transmitted by default. The Share button is the only feature that uploads a file, and only when you explicitly click it.
▶Can I convert to another format?
Yes. Click Export in the toolbar to save as STL (3D printing), OBJ (Wavefront), GLB (glTF binary), or PDF (snapshot of the current view).
▶Can I embed this viewer on my own site?
Yes. Click Embed in the toolbar to generate a one-line <iframe> snippet you can paste into any HTML page. You can choose whether the embed shows the viewer’s toolbar.
