Convert Your 3D Mesh/Model GLB Files to STL

to

Our free and fast tool will convert most 3D mesh or GLB (Graphics Language Transmission Format) model files to a standard STL (Standard Triangle Language) 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 GLB file click the Upload button above and select the file to convert. Once selected, the file will be converted to a STL file and will ready for download shortly afterwards. For more information about the GLB to STL conversion process see the conversion information section below for more information.

Upload a GLB

Click the "Upload a GLB File" button and select a GLB to upload. The maximum file size is 100MB.

Download your STL

Click the download link once completed to receive your STL file.

What STL formats can I convert to?

Our tool will save all STL files in binary format. Optionally, our tool will allow you to save to the non-standard color STL format.

How can I convert my GLB file to STL?

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

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

We aim to process all GLB to STL 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 GLB to STL conversion?

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

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

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

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

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

What if I am using an Ad Blocker, will that affect things?

Yes. Although you can use an Ad Blocker, if you like our GLB conversion tool please consider white-listing our site. When an Ad Blocker is enabled there are some conversion limits on some of our tools and processing/conversion times will be longer.

File format information for GLB to STL

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

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.

GLB Notes

If your GLB file contains textures, these will be ignored. If a material contains color information this will be translated where possible.

Supported Features

V2.0 and above files only
Mesh geometry

Extension	STL
Full Name	Standard Triangle Language
Type	3D Model
Mime Type	application/vnd.ms-pki.stl
Format	Text & Binary
Open With	Blender, MeshLab, CAD Assistant, DAZ Studio

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.

STL Notes

The standard STL file format does not support colored faces or vertices or texture information. The STL file generated by the tool will contain only raw mesh/triangle data by default which is perfect for 3D printing.

The tool also has an option to save the file to one of the non-standard formats that support colored faces such as VisCAM and SolidView which is perfect if you want to further process the STL in software which supports these formats.
