About OBJ to GLB Conversion

The OBJ to GLB converter is a powerful tool that transforms Wavefront OBJ files into the modern GLB (GL Transmission Format Binary) format. OBJ is one of the oldest and most widely supported 3D file formats, commonly used in 3D modeling software like Blender, Maya, and 3ds Max. However, GLB has become the standard for web-based 3D content, offering superior compression, faster loading times, and built-in support for textures, materials, and animations in a single file.

Our converter handles the complete conversion process, including geometry, textures (MTL files), and materials. Whether you're working with a simple OBJ file or a complex ZIP archive containing multiple textures and material definitions, our tool processes everything efficiently in your browser. The conversion maintains the quality and integrity of your 3D models while optimizing them for web use, game engines, and AR/VR applications.

How to Convert OBJ to GLB

  1. 1Select your OBJ file or ZIP archive containing OBJ, MTL, and texture files. You can drag and drop files directly onto the converter or click to browse your computer.
  2. 2The converter automatically detects and processes your files. If you upload a ZIP file, it will extract and link all textures and materials correctly.
  3. 3Wait for the conversion to complete. Processing happens in your browser using WebAssembly for maximum speed and privacy. Large files with many textures may take a few moments.
  4. 4Download your converted GLB file. The output is a single, optimized file ready for use in web applications, game engines like Unity or Unreal, or AR experiences.

💡 Tip: For best results, ensure your OBJ file includes an MTL file and all referenced textures are in the same directory or ZIP archive. This ensures materials and textures are properly converted.

Common Use Cases

Web 3D Development

Convert OBJ models exported from Blender or Maya to GLB for use in Three.js, Babylon.js, or other WebGL frameworks. GLB files load faster and are optimized for web browsers.

Game Development

Import OBJ assets into Unity or Unreal Engine as GLB files. The format preserves materials and textures while reducing file size, improving game performance.

AR/VR Applications

Prepare 3D models for augmented and virtual reality experiences. GLB is the preferred format for AR Quick Look on iOS and many VR platforms.

3D Model Sharing

Convert OBJ files to GLB for easier sharing and viewing. GLB's single-file format means no missing textures or broken material references.

Technical Specifications

  • Supports OBJ files with MTL materials and multiple texture maps (diffuse, normal, specular, etc.)
  • Handles ZIP archives containing OBJ, MTL, and texture files automatically
  • Preserves UV mapping, vertex colors, and material properties during conversion
  • Maximum file size: 500MB for individual files, 1GB for ZIP archives
  • Output GLB files are optimized with efficient compression while maintaining visual quality

Frequently Asked Questions

Find answers to common questions about this tool.

OBJ is a widely-used 3D file format that stores geometry data including vertices, faces, and texture coordinates. It's supported by most 3D software applications.
GLB files are more efficient for web use, support PBR materials, and are optimized for real-time rendering. They're also smaller in size and load faster in web browsers and applications.
Our converter supports geometry, vertex normals, texture coordinates, and basic materials from OBJ files. MTL material files are also processed when available.
Yes, we convert OBJ materials and textures to GLB format. However, some advanced material properties may be adapted to match GLB's PBR (Physically Based Rendering) workflow.
Simply click 'Select File' or drag and drop your file into the upload area. The conversion will start automatically and you'll be able to download the converted file once it's complete.
You can upload files up to 100MB in size. For most 3D models, this is more than sufficient. If you need to process larger files, please contact us for assistance.
Our conversion tools are designed to preserve quality as much as possible. However, some formats may have different capabilities. We use industry-standard algorithms to ensure minimal quality loss during conversion.
Processing time depends on file size and complexity. Most files are converted within 30 seconds to 2 minutes. Larger or more complex models may take longer.
Yes! This tool is completely free to use with no hidden fees, subscriptions, or limitations. You can convert as many files as you need without any cost.
Absolutely. We take privacy seriously. Your uploaded files are processed securely and automatically deleted from our servers after conversion. We never store or share your files.
