Free Online Blend to GLB Converter
Convert Blender .blend files to GLB for web 3D. Preserve PBR materials, textures, and animations. No Blender install needed.
How to Convert Blend to GLB
Upload Your .blend File
Drag and drop your .blend file onto the converter above, or click to browse. Your file is processed securely and never stored permanently.
Automatic Conversion
The converter extracts mesh geometry, materials, and textures from your Blender project and converts them to a single compact GLB file with PBR materials.
Download Your GLB
Once conversion is complete, download your GLB file and use it in any web 3D viewer, AR/VR application, or game engine that supports glTF.
Why Choose Our Converter
Free & No Sign-Up
Convert .blend to GLB for free with no registration, no watermarks, and no hidden costs. Upload and convert as many files as you need.
Web-Ready Output
GLB is the standard format for web-based 3D. The output file is ready to use in Three.js, Babylon.js, Google Model Viewer, and WebXR applications.
Material Preservation
The converter transfers mesh geometry and material properties to the GLB output. PBR materials from Blender are preserved for accurate web rendering.
No Blender Install Needed
Convert Blender files without installing Blender. Perfect for teams where only some members use Blender, or for quick conversions on the go.
2 Ways to Convert Blend to GLB
Choose between our online converter or Blender's built-in export.
Online Blend to GLB Converter (This Tool)
Best for: quick, no-install conversion
- Drag and drop your .blend file onto the converter above.
- Wait for the automatic conversion to complete.
- Download the GLB file and use it in your web project.
Pros: Free, no software install, works on any device, fast for most files.
Cons: Requires internet connection. Complex Blender features (particles, physics) may not transfer.
Blender (Built-in Export)
Best for: full control over export settings
- Open your project in Blender (free download).
- Go to File > Export > glTF 2.0 (.glb/.gltf).
- Select .glb format in the export options.
- Configure materials, compression, and other settings.
- Click Export glTF 2.0.
Pros: Free. Full control over export settings including Draco compression, material options, and animation export. Best fidelity.
Cons: Requires installing Blender. Slower for batch conversions.
Quick Checks Before You Convert
Blend to GLB conversion drops Blender-specific features. These checks ensure smooth conversion.
Mesh vs Other Objects
GLB only supports mesh objects, lights, cameras, and bones. Particle systems, physics simulations, and Blender-specific modifiers will not be included in the GLB output.
Apply Modifiers
Apply any modifiers (Subdivision Surface, Boolean, Mirror) in Blender before exporting. The converter may not apply modifiers automatically, resulting in missing geometry.
PBR Materials
For best results, use Principled BSDF materials in Blender. These map directly to GLB PBR materials. Legacy materials (Diffuse, Glossy) may not convert correctly.
Texture Paths
Ensure all texture images are packed into the .blend file (File > External Data > Pack All Into .blend). External texture references will be lost during conversion.
Blend vs GLB Format Comparison
| Feature | Blend | GLB |
|---|---|---|
| Full name | Blender Project File | GL Transmission Format (Binary) |
| Structure | Binary memory dump | Binary container + JSON |
| Materials | All Blender shaders | PBR only (Principled BSDF) |
| Animations | Yes (all types) | Yes (skeletal, morph) |
| Particles / Physics | Yes | No |
| Web support | No | Native (Three.js, WebXR) |
| File size | Large (full project) | Compact (web-optimized) |
| Primary use | 3D editing in Blender | Web 3D delivery |
Fixing Common Issues After Conversion
Typical errors after Blend to GLB conversion and how to resolve them.
GLB file is missing textures
Textures were not packed into the .blend file. Open Blender, go to File > External Data > Pack All Into .blend, save, then convert again.
Model appears different from Blender viewport
Some Blender material nodes and shaders are not supported in glTF. Use Principled BSDF for PBR-compatible materials. Check the glTF export settings in Blender for warnings.
Animations are missing in the GLB
Ensure animations are set as Actions on the armature or object. In Blender's glTF export dialog, check that Animation is enabled and the correct actions are selected.
File is too large for web
Enable Draco compression in Blender's glTF export settings (Mesh > Compression). This can reduce GLB file size by 50-90% with minimal quality loss.
What Is a Blend File?
.blend is the native file format of Blender, the free and open-source 3D creation suite. It stores complete scene data — meshes, materials, textures, animations, lights, cameras, modifiers, particle systems, and geometry nodes — in a single binary file.
Unlike interchange formats (OBJ, FBX, GLB), .blend files are project files that preserve the full Blender editing environment. Opening a .blend file in Blender restores the complete scene exactly as it was saved, including undo history, viewport settings, and node setups.
Blend vs GLB: why convert?
Blend files are for 3D authoring; GLB is for web delivery. Blend stores everything but only opens in Blender. GLB bundles geometry, PBR materials, textures, and animations into a single compact binary file that loads natively in web browsers via Three.js, Babylon.js, and Google Model Viewer. Converting Blend to GLB takes your Blender project to the web.

Frequently Asked Questions
How do I convert a .blend file to GLB?
Upload your .blend file using the converter above. The tool automatically converts the Blender project to a GLB file with mesh geometry and materials. Once conversion is complete, download the GLB file. Alternatively, use Blender's built-in glTF 2.0 export (File > Export > glTF 2.0).
Is this Blend to GLB converter free?
Yes, completely free. No registration, no watermarks, no hidden costs. Convert as many .blend files to GLB as you need.
Does converting .blend to GLB preserve materials?
Yes, but only Principled BSDF materials are fully supported. Blender's PBR materials map directly to glTF materials. Legacy shader nodes (Diffuse, Glossy, Mix) may not convert correctly. For best results, use Principled BSDF in your Blender project.
How do I export GLB from Blender?
In Blender, go to File > Export > glTF 2.0 (.glb/.gltf). In the export dialog, select .glb as the format. Check the options for materials, animations, and compression. Click Export glTF 2.0 to save your GLB file.
Does the GLB file include textures?
If textures are packed into the .blend file, they will be embedded in the GLB output. GLB is a self-contained format that bundles geometry, materials, and textures into a single file. Ensure textures are packed (File > External Data > Pack All Into .blend) before converting.
What is the difference between .blend and GLB?
.blend is Blender's native project format that stores everything including UI state, particles, and simulations. GLB is a web-optimized delivery format that stores only meshes, materials, textures, and animations. Use .blend for editing in Blender; use GLB for deploying 3D content to web browsers and AR/VR.
Can I convert .blend to GLB with animations?
Yes. Skeletal animations, morph targets, and object transformations can be exported to GLB. Ensure your animations are set up as Actions in Blender. In the glTF export dialog, verify that Animation is enabled. The converter will include embedded animation data in the GLB file.
Can I convert .blend to GLB without Blender?
Yes. Our online converter processes .blend files without requiring Blender to be installed. This is useful for quick conversions on computers where you cannot install software, or for team members who do not use Blender.
How do I reduce GLB file size from Blender?
Enable Draco mesh compression in Blender's glTF export settings (Mesh > Compression). This reduces file size by 50-90%. You can also simplify meshes, reduce texture resolution, and remove unused objects before exporting.
What Blender features are not supported in GLB?
GLB does not support: particle systems, physics simulations, fluid simulations, smoke and fire, hair, Blender's procedural node materials (beyond Principled BSDF), custom properties, and UI layout. Only meshes, armatures, animations, lights, cameras, and PBR materials transfer to GLB.
