Which files can I convert to GLB on this page?

This GLB converter accepts supported 3D model formats such as 3MF, FBX, glTF, OBJ, PLY, STL, USDZ, and VOX. Image-to-GLB workflows use separate image converter pages because they generate new 3D geometry rather than transcode an existing model.

GLB is the binary container form of glTF. It can package the glTF scene description, binary buffers, and images in one file, although a GLB asset may still reference external resources. It is designed for efficient runtime delivery rather than preserving authoring-tool history.

How do I use the GLB converter?

Upload a supported 3D model, keep GLB selected as the target, and start the conversion. The model is processed in a browser worker and the resulting .glb file is downloaded to your device.

Will materials, textures, and animation be preserved?

Not always. Preservation depends on what the source format contains and what the converter can map. STL has no materials or animation, while OBJ may depend on separate MTL and texture files. Inspect the GLB in its destination viewer before publishing it.

What is the difference between GLB and glTF?

A .gltf file is JSON and often references separate .bin and image files. A .glb file stores the glTF JSON and binary payload in one container, which is convenient for upload and delivery. Both represent glTF assets and may still reference external resources.

When is GLB the right output format?

GLB is a practical delivery format for web viewers, product previews, AR, games, and other real-time applications. Conversion does not optimize polygon count or texture size automatically, so test loading time and visual quality in the actual target environment.

Is my 3D model uploaded?

Supported 3D model conversions run locally in a browser worker. The source model does not need to be uploaded for the format conversion.

Free Online GLB Converter for 3D Model Files

Convert OBJ, FBX, STL, 3MF, PLY, USDZ, and other supported 3D model files to GLB in your browser. Download the asset, then inspect materials, textures, scale, and animation in its target viewer.

What This GLB Converter Does

Common 3D model inputs

Convert supported 3D model files—including 3MF, FBX, glTF, OBJ, PLY, STL, USDZ, and VOX—to a GLB asset for downstream delivery.

Browser-based model conversion

The GLB converter processes supported model files in a browser worker, with no desktop converter installation or model upload required.

A practical delivery container

GLB can bundle scene data, binary buffers, and images into one portable container, making it useful for web, AR, and real-time delivery.

Check the exported asset

Inspect geometry, scale, materials, textures, skinning, and animation in the target viewer because format conversion cannot guarantee every source feature will transfer.

When Should You Convert a 3D File to GLB?

GLB is the binary container form of glTF. It is designed for efficient runtime delivery and can package scene data, buffers, and images together, but it does not preserve authoring-tool history.

Convert to GLB when

Convert to GLB when a web viewer, product preview, AR experience, or game pipeline needs a portable runtime asset.
Use GLB when packaging the glTF scene description and binary resources into one file simplifies delivery.

Keep the source file when

Keep the source format when you need editable authoring data, modifiers, constraints, or application-specific scene settings.
Retain the source model when exact material, texture, rig, or animation transfer matters; conversion can only map supported data.

How to Use the GLB File Converter

Choose a supported 3D model, convert it to GLB locally, then inspect the result in the viewer or application that will deliver it.

Upload a 3D model file

Choose a supported source format such as OBJ, FBX, STL, 3MF, PLY, USDZ, glTF, or VOX.

Convert the model to GLB

GLB stays locked as the output while the browser worker performs the model conversion.

Download and check the result

Open the GLB in its target viewer and verify geometry, scale, materials, textures, and animation before publishing.
