Convert Your 3D Mesh/Model KMZ Files to GLB

to

Our free and fast tool will convert most 3D mesh or KMZ (Keyhole Markup 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. Our conversion tool can also batch convert multiple KMZ files; up to 25 files at a time can be converted.

To convert your KMZ 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 be ready for download shortly afterwards. For more information about the KMZ to GLB conversion process, see the conversion information section below.

Frequently Asked Questions

How can I convert my KMZ file to GLB?

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

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

We aim to process all KMZ 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 KMZ to GLB 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 KMZ to GLB on ImageToStl.com?

Yes, of course! We do not store the KMZ file you submit to us. The resulting GLB file, once created is deleted 15 minutes after upload and the download link will expire after this time.

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

Yes! Our KMZ 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.

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

Yes. Although you can use an Ad Blocker, if you like our KMZ 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.

Can I get support with converting my KMZ to GLB?

Yes. When you have converted your KMZ to GLB, there is a "Feedback" option that you can use to let us know of any issues you encountered when converting your file.

I have several KMZ files; can I batch convert my KMZ to GLB?

Yes! Our KMZ tool supports full batch conversions. You can upload up to 25 and KMZ files at a time. Our tool will convert them all as quickly as possible. Once completed, you can either download the GLB files individually or download them all in a single ZIP file.

Description

A KMZ, which is short for Keyhole Markup Zip, is a compressed ZIP file used to contain geographic data, including 3D models, images, and terrain.

The KMZ format comprises a single KML file containing XML data and supporting assets such as images and 3D models using the Collada DAE format, all contained within a compressed ZIP format. There are several specialist map-rendering applications that can open KMZ files.

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 modeling applications such as Blender and MeshLab. The GLB format is an open standard that is maintained by the Khronos Group.

GLB Notes

If your original model file contains texture images and other texture-related data, these will be included in the final GLB file.

Supported Features

  • V2.0 and above files only
  • Mesh geometry
  • Materials
  • Textures

Unsupported Features

  • Animations

How does it work?

Converting from the KMZ file format to GLB can be a complex process, and any tool used for this conversion process needs to be able to handle a variety of data conversion tasks as well as identify any defects within the 3D model and fix them. Here we will explain the conversion process used by our tool to accurately convert your KMZ file to a valid GLB 3D model. Let's start with the conversion process, which involves the following steps:

Step 1: Read the Source KMZ File

In its simplest form, an KMZ file is a binary data file containing 3D data such as vertices, faces, normals, and more. When combined, these make up the 3D model you see on your screen.

For more information regarding the KMZ file format, please see this great article that goes into a lot of detail explaining the KMZ format.

Step 2: Process File Data

With the KMZ file data read, our tool generates an internal representation of the full 3D model and will attempt to fix any geometry issues encountered. Along with repairing any issues with the 3D model, the tool will remove any duplicated vertices and prepare the model for exporting to the GLB format.

Step 3: Saving to the GLB Format

With the conversion process entering its final stages, our tool now needs to take the in-memory 3D model we have created in step 2 and convert it to the GLB format.
