Convert Your 3D Mesh/Model STL Files to GLB

Our free and fast tool will convert most 3D mesh or STL (Standard Triangle Language) model files to a standard GLB (Graphics Language Transmission Format) file that can then be edited further in most popular 3D editing packages such as Blender or 3D printed without any further processing.

To convert your STL file click the Upload button above and select the file to convert. Once selected, the file will be converted to a GLB file and will ready for download shortly afterwards. For more information about the STL to GLB conversion process see the conversion information section below for more information.

FAQ

What STL formats can I convert from?

You can convert from both text and binary STL files. If your STL file contains color information we will bring this over.

How can I convert my STL file to GLB?

First click the "Upload..." button, select your STL file to upload. Select any configuration options. When the STL to GLB conversion has completed, you can download your GLB file straight away.

How long does it take to convert my STL to GLB?

We aim to process all STL to GLB conversions as quickly as possible, this usually takes around 5 seconds but can be more for larger more complex files so please be patient.

How accurate is the STL to GLB conversion?

We aim to create the most accurate conversions with our tools. Our tools are under constant development with new features being added every week.

Is it safe to convert my STL to GLB on ImageToStl.com?

Yes, of course! We do not store the STL file you submit to us. The resulting GLB file, once created is deleted 1 hour after upload and the download link will expire after this time.

Can I convert STL to GLB on Windows, Linux, Android, iOS or Mac OS?

Yes! Our STL to GLB tool will run on any system with a modern web browser. No specialist software is needed to run any of our conversion tools.

Description

The STL file format has its roots in the 1980's and is the native file format for 3D Systems stereolithography CAD software. The format defines a triangulated mesh with vertices and faces and is a popular format for sharing 3D printable model files.

There were several formats that attempted to extend the STL format namely SolidView and VisCAM whose formats included limited 15-bit color information for each mesh face which is often ignored by most modern 3D software. The STL format can be either Text or Binary, our tools will support both formats.

Description

The GLB file format which can also have the GLTF file extension depending on whether the content is binary or text/Json is a 3D file format used to describe 3D worlds and as such contains geometric data such as vertices, faces, normals, animations and other 3D scene related data.

The format, described by its creators as the "JPEG of 3D", has gained in popularity and is supported by a wide range of 3D modelling applications such as Blender and MeshLab. The GLB format is an open standard which is maintained by the Khronos Group.

STL Notes

Standard STL files do not contain material or color information so this cannot be imported. There are however two formats (VisCAM and SolidView) that attempted to add color information to the STL file format. If our tool detects this additional color information it will attempt to import this information.

Supported Features

  • Mesh geometry
  • Face colors via the VisCAM and SolidView formats
  • Binary and Text versions supported
