Free Online glTF Binary (GLB) Viewer (No Signup)

GLB is the binary form of glTF, the modern open standard for sharing 3D scenes on the web — geometry, PBR materials, textures, and animations in a single compact file. View and convert GLB models in your browser.

Works in Chrome, Firefox, Safari, and Edge — no plugin required

Private by default — files are parsed locally in your browser. Uploading is only required if you choose to share a link.

What Is a glTF Binary (GLB) File?

GLB (glTF Binary) bundles geometry, materials, textures, skeletal animation, and metadata into a single binary file. It’s maintained by the Khronos Group and is supported by Blender, Unity, Unreal Engine, three.js, Babylon.js, Google’s <model-viewer>, Apple Reality Composer, and pretty much every other modern 3D engine.

If GLB is the “PNG of 3D,” then JPG is its cousin OBJ: smaller scope (no PBR, no animation), wider legacy compatibility.

Who Uses 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.

Common Use Cases

Preview a GLB before dropping it into a Unity / Unreal / web project
Verify a model bought from Sketchfab or CGTrader
Convert GLB to STL for 3D printing
Convert GLB to OBJ for use in legacy tools (3ds Max, Maya, Cinema 4D)
Generate a PDF snapshot for client review

Features

Open Instantly

Drag and drop a .glb file — it renders in seconds with PBR materials and textures.

PBR Materials

Renders MeshStandard and MeshPhysical materials with transmission, clearcoat, IOR, and emissive support.

Textures + UVs

Image textures, vertex colors, and multiple UV channels are all loaded automatically.

KHR Extensions

Supports the common KHR_materials_* extensions for glass, clearcoat, transmission, and volume.

Convert to OBJ

Export your GLB as Wavefront OBJ for use in legacy tools and CAD software.

Convert to STL

Save as STL for 3D printing or simulation, with all geometry triangulated.

Export as PDF

Generate a snapshot PDF of the current view for client reviews or proposals.

No Upload Required

Your GLB is parsed entirely in your browser via three.js GLTFLoader.

Same as model-viewer

Uses the same renderer as Google’s <model-viewer> web component for consistent visuals.

Embed on Any Site

Add the GLB viewer to your website with a single iframe embed code.

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

Your glTF Binary (GLB) files are parsed entirely in your browser. Nothing is uploaded, stored, or shared unless you explicitly click the Share button. Shared files are hosted for 90 days then deleted.

Frequently Asked Questions

▶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>.

▶Are animations supported?

The geometry, materials, and skeleton are loaded. Animation playback isn’t yet exposed in the toolbar — if this is important to you, click Report to vote for it.

▶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 30 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.
