About This Tool

This OBJ to GLB converter allows you to transform your 3D OBJ model files into the modern GLB format used by web applications, AR/VR, and game engines. The tool processes OBJ files with their associated MTL materials and texture images, converting them into a single, efficient GLB file that's optimized for web use. The conversion preserves vertex data, UV mapping, normals, materials, and textures. No software installation required - everything runs securely in your browser with optional server-side processing for complex models.

Frequently Asked Questions

Find Quick Answers

What is the difference between OBJ and GLB formats?

OBJ is a legacy 3D model format that stores geometry as plain text, often requiring separate MTL and texture files. GLB is a modern binary format that packages 3D geometry, materials, textures, and animations into a single efficient file, optimized for web and real-time applications.

Does the converter preserve textures and materials?

Yes, when you upload OBJ files with associated MTL and texture files (JPG, PNG), the converter will preserve materials and embed textures into the GLB file. The tool supports diffuse, specular, normal, and emission maps.

Is there a file size limit for conversion?

The client-side conversion works best for models under 50MB. For larger models, the server-side processing can handle files up to 200MB. Complex models with high polygon counts may take longer to process.

Can I convert multiple OBJ files at once?

Currently, the tool processes one OBJ file at a time to ensure quality conversion. If you have multiple models, convert them individually and combine them in your 3D editing software.
