Free GLB Optimizer & CAD Converter for VR

Standard 3D files are often too large and resource-heavy for VR headsets like Meta Quest. Without optimization, you'll experience long loading times, stuttering, and poor performance. Our GLB Optimizer converts your files into a VR-friendly format that loads up to 5x faster, runs smoothly without lag, and uses significantly less memory - giving your users a better experience. Read our VR/AR optimization guide for detailed best practices.

Simply upload your FBX file using the converter above. RAUM automatically optimizes textures, reduces mesh complexity, and ensures compatibility with Meta Quest 2 and Quest 3 memory limits (20MB per scene). The conversion typically takes 30-60 seconds depending on file complexity.

Yes! RAUM Converter supports STEP (.stp, .step) and IFC formats commonly used in architectural and engineering workflows. This is perfect for BIM-to-VR workflows, architectural visualization, and product design reviews. The converter preserves materials and maintains geometric accuracy.

Yes, RAUM Converter is completely free for public use with no account registration required. You can convert unlimited files. RAUM users can integrate optimized models into RAUM's VR collaboration platform for team collaboration and project management.

RAUM is specifically optimized for VR applications with memory-constrained devices like Meta Quest and support for CAD formats (STEP, IFC).

For optimal performance on Meta Quest, individual models should be under 8MB, with scenes staying below 20MB.

Yes! RAUM Converter preserves all materials, textures, and PBR properties from your source files. We convert textures to KTX2 format for optimal file size and VR performance, while maintaining visual quality.

RAUM uses industry-standard optimization including: Meshoptimizer compression (EXT_meshopt_compression) for reduced file sizes, texture format conversion to KTX2 with BasisU compression for memory efficiency, mesh instancing (EXT_mesh_gpu_instancing) to reduce draw calls, and vertex/mesh cache optimization to improve GPU rendering performance on VR headsets.
