About GLB to OBJ Conversion

Did You Know?

  • GLB format was developed by the Khronos Group in 2015 as a binary container for glTF
  • GLB efficiently packages all assets (models, textures, animations) into a single binary file
  • OBJ format dates back to the 1980s from Wavefront Technologies
  • Converting to OBJ enables compatibility with older software that doesn't support GLB

Technical Insight

Converting GLB to OBJ involves extracting 3D geometry and material information from the binary container and transforming it into text-based format.

The process requires parsing binary structures to access JSON metadata and buffers containing vertex data, normals, UVs, and other attributes.

While geometry is preserved, OBJ doesn't support skeletal animations or morph targets, and PBR materials must be approximated using simpler definitions.

GLB vs OBJ Comparison

GLB Format

  • Binary format (smaller file size)
  • Supports PBR materials
  • Includes animations & morph targets
  • Efficient for web applications
  • Newer format (2015)

OBJ Format

  • Text-based format (larger file size)
  • Simple material definitions
  • No animation support
  • Widely compatible with 3D software
  • Classic format (1980s)

Frequently Asked Questions

Why should I use an online GLB to OBJ converter?

An online GLB to OBJ converter allows you to quickly transform 3D models between formats without installing specialized software. It's convenient for converting models from any device with a browser.

Will I lose geometry or materials when converting GLB to OBJ?

Our converter maintains the original geometry and basic material properties. However, OBJ format has some limitations compared to GLB, so advanced PBR materials and animations may not transfer completely.

How long does the conversion process take?

Conversion time depends on the model size and complexity. Most conversions complete within a few minutes.

Is my model data secure when using this converter?

Yes, we prioritize your privacy. Your files are securely stored on our servers and automatically deleted after 24 hours to ensure complete privacy and security.

Is this tool free to use?

Yes, our GLB to OBJ converter is completely free to use without any hidden charges. You just need to create an account to get started.

How long do you store our data?

Your model data is temporarily stored on our secure servers and automatically deleted after 24 hours for your convenience and privacy.

What is the limit of GLB file size?

The maximum GLB file size limit for conversion is 100MB.
