Free Online STEP to GLB Converter

Here is our free to use STEP to GLB 3D model converter tool that will take your STEP file and convert it to the GLB format ready for loading into your favourite 3D modeling package. Our 3D model converter supports batch processing of your files and can convert up to 20 STEP files at one time.

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 STEP file file, when uploaded to our server, will be deleted 15 minutes after upload. Please download your converted STEP file file before this time.

The STEP to GLB model conversion tool will analyse your STEP file and convert its 3D mesh data including vertices, surfaces and where applicable vector normals and texture coordinates to the GLB format whilst maintaining the structural accuracy of your original STEP 3D model file.

The STEP file format, also known as ISO 10303-21, is a 3D file format used within the area of computer-aided design (CAD) as a way to exchange data between different applications. The STEP format is essentially a plain text file containing commands used to describe the 3D object.

Due to the standardized nature of the format, there is support for importing STEP files into many CAD applications. STEP files can, however, become quite large, and some complex files can take a long time to import into a 3D project.

Mesh Geometry

The STEP format is not a mesh-based format; converting a STEP file to a mesh format is possible via most CAD applications via a tessellate function.

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.

Frequently Asked Questions

How do I convert my STEP to GLB?

First, click the "Select File" button and choose your STEP file. We will upload and convert your STEP file. Once the conversion from STEP to GLB completes, use the provided link to download your GLB file.

How long does it take to convert my STEP file to GLB?

We aim to process all STEP to GLB file conversions as soon as possible; this should take around 5 seconds; however, this may be longer for larger files.

Is the STEP format suitable for 3D printing?

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