Free online BLEND to GLTF converter

Source format: Blender .blend

BLEND is the native project file format used by Blender, the open-source 3D creation suite. It can store a complete scene, including meshes, materials, textures, cameras, lights, animation data, modifiers, physics settings, and more. Artists, game developers, animators, and VFX creators use .blend files as working project files while modeling, rigging, animating, and rendering.

A .blend file is ideal for editing inside Blender, but it is not a universal interchange format. If you need to use the model in a game engine, web viewer, or another 3D application, exporting to a more portable format such as glTF is often the best choice.

Target format: glTF .gltf / .glb

glTF (GL Transmission Format) is a modern 3D asset format designed for efficient transmission and real-time rendering. It is widely supported by game engines, web platforms, AR/VR tools, and 3D viewers. The format is especially popular for PBR materials, animations, skeletal rigs, and compact asset delivery.

glTF comes in two common forms: .gltf, which is a JSON-based scene description that usually references external binary and texture files, and .glb, which is a single binary container that bundles geometry, materials, animations, and often textures into one file. The main advantages of glTF are good interoperability, fast loading, and efficient runtime performance.

How to convert .blend to .gltf

The best tool for this conversion is Blender itself, because it can read the full project data and export it directly to glTF with the least loss of information.

1. Open Blender.
2. Load your .blend file with File → Open.
3. Check the scene for export readiness: apply transforms if needed, verify materials, and make sure textures are linked correctly.
4. Choose File → Export → glTF 2.0.
5. Select the desired output type: glTF Separate for a .gltf file with external resources, or glTF Binary for a single .glb file.
6. Set export options such as Selected Objects, Apply Modifiers, animation export, and texture handling as needed.
7. Click Export glTF 2.0 and save the file.

If you only need a quick conversion without installing software, you can also convert the file on 101convert.com for free.

For command-line workflows, Blender can also export glTF through its scripting and batch capabilities, but the built-in export dialog is usually the simplest and most reliable method for most users.

Notes on quality, compatibility, and limitations

Not every Blender feature maps perfectly to glTF. Complex node setups, certain procedural materials, custom shaders, simulation caches, and some modifiers may not export exactly as they appear in Blender. glTF is optimized for real-time use, so it favors standardized materials and geometry over Blender-specific effects.

For best results, use simple PBR-compatible materials, bake unsupported effects into textures when necessary, and test the exported file in your target viewer or engine. If your scene includes animations, verify that bone rigs, keyframes, and action ranges export correctly. Also note that .gltf may create multiple companion files, while .glb is easier to distribute because it keeps everything in one package.
