Free Online GLB Converter

This is our free-to-use GLB file conversion tool that can be used to convert your GLB file into any number of other 3D model formats. Our GLB converter will extract the 3D model geometry contained within your file and accurately convert it to the desired format without any loss of detail. Our GLB converter also has a batch processing mode whereby you may upload up to a maximum of 20 files to be converted in one go.

Drag and drop your files here to upload or click the button above.
A maximum of 20 files can be converted at once.

Please note: Your GLB file file, when uploaded to our server, will be deleted 15 minutes after upload. Please download your converted GLB file file before this time.
Our GLB conversion tool supports converting to the following file types:

Our GLB converter will extract the vertices, faces, and other geometric data that forms the structure of your 3D model and convert it to the requested format. If the selected format supports external texture files, these can be uploaded along with your GLB model file, and these will be processed accordingly.

GLB file information

Type3D Model
Mime Typemodel/gltf-binary

The Khronos Group developed GLB files as a format for storing complex 3D models. The format was first introduced in 2015 and aimed to create a format that could be easily adopted by third-party developers. Subsequent versions have followed this initial release, adding more complex features.

Support for GLB files is growing and has found support in many modern 3D model editors, such as Blender, which currently supports importing from and exporting to the GLB format.

Mesh Geometry

At the heart of the GLB format is its ability to store 3D geometric mesh data, which comprises vertices, faces, normals (both face and vertex normals), and texture coordinates. The data is saved in a compact binary format, ensuring GLB files are compact and easy to distribute.


GLB files support a wide range of materials, from simple single-color materials to richly textured materials. Textures such as diffuse, specular, and bump mapping textures are supported with the texture files embedded within the main GLB file to ease the distribution of GLB files.

GLB Converter Capabilities

As materials containing texture and color information are both supported by the GLB format, our tool will do its best to include these materials, including any texture files, in the converted file.

Frequently Asked Questions

Is it free to use the GLB file conversion tools?

Yes, there is no cost to using our conversion tools.

Are there any GLB file conversion limits?

At this time, we do not have any usage limits other than the maximum of 20 file uploads per conversion run.

How long do I need to wait for my converted file to be completed?

The size of your GLB file will affect processing times, so please allow for this. For smaller files of around 5MB, our tools will aim to have it completed within a few seconds.

How is my GLB file converted, whats involved?

When you upload your file to our site, we use a set of bespoke conversion components to, as accurately as possible, convert your file to the requested format. When the conversion is complete you will see a download link with which to retrieve your converted file.

Is the GLB format suitable for 3D printing?

No. Most 3D printing slicer software will not support the GLB format. It is recommended to convert your GLB file to the STL format if you wish to 3D print it.

Is it safe to convert my GLB on

Yes, your files are automatically deleted from our servers after 15 minutes.

Can I convert my GLB file using Android, iOS, Mac OS or Linux?

Yes, you can. Our GLB file converters only require a modern web browser to convert your files.
