Convert your 3D model file to compressed gLTF format  online

We have added support for Draco-compressed glTF 3D model files. Now you can use our tools to convert your 3D file to a Draco-compressed gLTF file. You can also view your Draco-compressed gLTF file files directly within your browser.

Background and overview of glTF

glTF (GL Transmission Format) is an open standard file format for 3D scenes and models. It was developed by the Khronos Group, a consortium of companies dedicated to creating open standards for graphics, media, and parallel computing. The purpose of glTF is to provide a common format that can be used for transferring 3D content between different tools and engines in a way that is efficient, reliable, and platform-independent.

glTF is designed to be lightweight, extensible, and easy to use. It uses JSON (JavaScript Object Notation) for data representation, which makes it simple to parse, manipulate, and generate with a variety of programming languages. It also supports embedded binary data for geometry, animations, and other resources, which allows for compact and fast loading of 3D assets.

glTF has gained popularity in recent years due to its growing support by major software vendors and platforms. It is now widely used in game development, virtual reality, augmented reality, e-commerce, and other fields where 3D graphics and visualization are important. With the increasing demand for web-based 3D content, glTF has become a crucial format for delivering immersive experiences on the web.

Advantages and features of the glTF format

There are several advantages and features that make glTF a popular and useful format for 3D content:

glTF is designed to be lightweight and efficient, which means it produces small file sizes without sacrificing quality. This makes it ideal for web-based applications where bandwidth and storage space are limited.

glTF is an open standard format that can be used by any software or platform that supports it. This means that it can be shared and used between different tools and engines without the need for complex conversions or custom workflows.

glTF is designed with extensibility in mind, which means that it can be easily extended to support new types of data or features as they become available. This allows it to evolve and adapt to changing needs and technologies over time.

glTF includes support for physically-based rendering (PBR) materials, which provide realistic lighting, reflections, and shadows in 3D scenes. This makes it a popular choice for game development, architecture visualization, and other fields where high-quality visuals are important.

glTF includes support for animations and skeletal animations, which allows for complex character animations and dynamic visual effects.

Overall, the compactness, flexibility and versatility of glTF make it a powerful format for creating and sharing 3D content across different platforms and applications.

Draco-compressed glTF fille

Draco is a compression library developed by Google that is designed to compress 3D geometry data, such as meshes and point clouds. glTF (short for "GL Transmission Format") is an open standard format for 3D graphics that enables efficient transmission and loading of 3D scenes and models.

A Draco-compressed gLTF file is simply a glTF file that has been compressed using the Draco library. This can result in significant reduction in file size while still maintaining high quality and fidelity of the 3D model. This makes it useful for applications where bandwidth or storage space is limited, such as web-based applications or mobile devices.
