Free Online 3DM to GLB Converter

You can use our 3DM to GLB conversion tool to quickly and easily convert your 3D model files for free. You may upload up to 20 files at one time, and our batch 3DM to GLB converter will process each 3D model and present you with a download link for each file once completed.

Select File(s)

Or drag and drop your files here to upload.
A maximum of 20 files can be uploaded at once.

Please note: Your 3DM file, once uploaded to our server, will be deleted 15 minutes after upload, so please download your converted 3DM file before this time.

Our 3D model 3DM to GLB tool will load your 3DM file and, where supported, attempt to extract all the relevant 3D features, such as geometry, textures, and animations. To access the 3D conversion configuration options, click the button when you have selected your files. The current options support the ability to voxelize your 3D model and more.

Frequently Asked Questions

How can I convert my 3DM file to GLB?

First, click the "Upload..." button and select your 3DM file to upload. Your 3DM file will be uploaded to our servers. When the 3DM to GLB conversion has completed, you can download your GLB file right away.

How long does it take to convert my 3DM to GLB?

We aim to process all 3DM to GLB conversions as quickly as possible; this usually takes around 5 seconds; however, this can be longer for certain files, so please be patient.

How accurate is the 3DM to GLB conversion?

We aim to provide the best conversion experience. Our tools are under constant review and development, with new features being added every week.

How does converting 3DM to GLB work?

In order to successfully convert an 3DM formatted file to the GLB format, our converter tools will perform several initial checks to ensure the file provided is indeed an 3DM file. There are many files out there where the file type extension does not match the data contained within the file. Along with these file type checks, our tools will do additional checks to ensure the file is correctly formatted to match the provided file type. There are many tools out there that do not always create 3DM files to the exact specification.

Take your 3DM file

An 3DM file is a binary data file containing 3D data that makes up the 3D model, including vertices, faces, texture coordinates, and more. To guarantee efficient conversions, our tool will check all data that is contained within the 3DM file and remove any information that is duplicated. This not only ensures the conversion completes more quickly, but also the generated GLB file size is smaller.

Convert the data from 3DM to GLB

Now that the data from the 3DM file has been processed, our tool can apply any conversion specified options, such as enabling Voxel mode, and with these applied, prepare the data to be converted to the final GLB file format. Part of this process ensures checking the capabilities of the GLB format and removing any data that cannot be represented.

Save to the GLB format

At this point, the 3DM to GLB conversion tool will have the 3D model in a state that is ready to be transferred to the GLB format. Our tool creates the GLB file, ensuring all the model data is present and is formatted to match the GLB file specification to ensure the file opens in compatible GLB file editors.

File format information for 3DM and GLB

Extension	3DM
Full Name	Rhinoceros 3D
Type	3D Model
Mime Type	x-world/x-3dmf
Format	Binary

The 3DM file format is a 3D Computer Aided Design (CAD) format primarily used by the Rhinoceros CAD software. It enables the storage of both simple and complex 3D models within a standard package and has found many uses within the architectural, engineering, and manufacturing arenas.

The format allows the storage of 3D model geometric data, including mesh and texture coordinate data. This 3D data is stored in the NURBS format, allowing complex objects to be represented with high precision.

Although primarily designed for use with the Rhinoceros CAD software, 3DM files enjoy support amongst other CAD software, with many supporting the import and export of data to the format.

3DM Converter Capabilities

Our 3DM 3D Model/Mesh tool does not support any colour material data contained within 3DM files, so the converted file will not contain any colour information.

Extension	GLB
Full Name	Graphics Language Transmission Format
Type	3D Model
Mime Type	model/gltf-binary
Format	Binary
Opens With	Blender, MeshLab

GLB files are the binary equivalent of the GLTF 3D file format developed and maintained by the Khronos Group. GLB files are designed to be an open and expandable 3D format that can store 3D graphics and their assets, such as textures, animations, and more.

The content of a GLB file is binary and enables highly efficient storage and transmission of 3D data. This efficiency of size, along with its ability to store all the associated assets in the same file, has made GLB files one of the preferred formats for use within 3D web content and other applications.

Due to their open format, GLB files are widely supported by 3D editing software. The format has gained traction amongst videogame developers and other 3D artists as a primary means of exchanging 3D data between different applications.

GLB Converter Capabilities

Our 3D conversion tool does not support colour or material information in GLB files, so your file will not contain any colour information.

Information for converting from 3DM to GLB

Your 3DM file will be converted to a GLB file using our unified 3D model and mesh conversion tool. Our 3DM 3D tool performs accurate conversions of 3D elements such as vertices, faces, normals, and relevant material information. Our tool will not attempt to transfer any colour information if it is present in your 3DM file; your final 3D model will contain only geometry data.
