GLB Viewer - Frequently Asked Questions

Common questions about viewing GLB 3D models online

1

Which formats can I view?

View all major formats including GLB, GLTF, OBJ, FBX, STL, PLY, VOX, USDZ, and 3MF directly in your browser without plugins. Our WebGL-powered engine delivers desktop-quality rendering with real-time interaction, supporting industry-standard workflows from CAD, game development, and 3D printing applications.
2

How secure is 3D model viewing?

Files are cached temporarily and auto-deleted after refresh. Encrypted HTTPS connections ensure your intellectual property remains confidential during sessions. All processing happens locally in your browser using WebAssembly technology—no files are ever uploaded to our servers, guaranteeing complete privacy and security for sensitive projects.
3

Can I view 3D models on smartphones?

Yes. Our responsive viewer works seamlessly across desktops, tablets, and mobile devices (iOS/Android) with touch-optimized rotation/zoom controls. Advanced gesture recognition supports pinch-to-zoom, two-finger rotation, and pan gestures. Mobile-specific optimizations ensure smooth performance even on lower-end devices while maintaining visual quality.
4

Is there a 3D file size limit?

Files up to 50MB load instantly. For larger models, we recommend using our desktop optimization tools before uploading. Our progressive loading technology with mesh decimation and texture compression ensures optimal performance. Consider converting high-poly models to optimized formats for web viewing while preserving visual quality.
5

How accurate is the 3D rendering?

We replicate textures, lighting, and geometries with 98% precision compared to native software. Regular updates enhance material shading and mesh accuracy. Our advanced WebGL pipeline supports PBR materials, real-time shadows, and IBL lighting. Continuous improvements include better normal mapping, subsurface scattering, and optimized rendering for complex scenes.
6

Do I need an account to view 3D models?

No! Our 3D viewer is completely free to use without registration or creating an account. Simply upload and start viewing your 3D models instantly. Enjoy full access to all viewing features, animation controls, and export options without any limitations. No personal data collection, no tracking, no commitment required.
7

What features does GLB format support?

GLB format supports meshes, materials, textures, animations, and lights. As binary glTF format, it's optimized for web delivery and ideal for online 3D content. Single-file packaging includes embedded textures and animations, making it perfect for AR/VR applications, game engines, and web deployment. Supports PBR materials, skeletal animations, and morph targets.
8

What's the difference between GLB and GLTF?

GLB is binary format that packages all resources in one file for faster loading. GLTF is JSON format with separate resources, making it easier to edit and debug. GLB offers 30-50% faster loading times and simplified deployment, while GLTF provides human-readable structure for development workflows. Choose GLB for production and GLTF for development iterations.
9

Do GLB animations play correctly?

Yes! Our viewer fully supports GLB animations including skeletal, morph, and material animations. You can control playback, pause, and loop animations. Features timeline scrubbing, variable playback speed, and animation blending. Supports complex character rigs, facial animations, and procedural material effects with smooth interpolation.
