The Power of Draco Compression in GLTF and GLB File Formats

GLTF and GLB File Formats with Draco Compression

As the demand for immersive 3D experiences continues to rise, the efficiency of file formats becomes increasingly crucial. GLTF (Graphics Library Transmission Format) and GLB (Binary Representation of GLTF) have emerged as popular choices for storing 3D models due to their ability to encapsulate geometry, textures, and animations. What sets them apart is their integration with the efficient Draco algorithm from Khronos group, enabling the compression of geometry data.

Efficiency of Draco Compression

Draco compression can often reduce the size of GLTF and GLB files to 20% of their original or even lower. This is particularly beneficial when transferring files over a network, as smaller files can be transferred more efficiently. Reduced file sizes mean faster loading times and a smoother user experience, especially in applications like 3D modeling, virtual reality, and augmented reality where large amounts of data are often involved.

Autoconverter Software and Draco Compression

To harness the benefits of Draco compression for GLTF and GLB files, users can leverage our Autoconverter software. This versatile tool empowers users to save GLTF files with Draco compression, offering a range of compression levels to suit specific requirements. Whether users prioritize speed or maximum compression, Autoconverter allows them to choose between:

  • Fastest Compression Level: Provides quick compression with moderate file size reduction.
  • Maximum or Ultra Compression Levels: Achieves the highest level of compression, resulting in significantly smaller file sizes, but at the cost of longer compression times.


In conclusion, Autoconverter software is an invaluable tool for optimizing GLB and GLTF file sizes, especially for network transfers. By leveraging the power of Draco compression, Autoconverter allows users to significantly reduce file sizes without sacrificing the quality of 3D models. Whether you’re a game developer, a 3D artist, or just someone who needs to transfer 3D files efficiently, our Autoconverter and Draco compression could be the solution you’re looking for.
