Core Capabilities
From Compression to Delivery, All in One
Draco geometry compression
Up to 90% size reduction, native support in Three.js / Babylon.js, fine-grained parameter tuning
Meshopt engine
Higher compression, faster decode, auto-fallback to Draco on failure
KTX2 GPU textures
Cut texture size by 90%, GPU-native decoding without CPU cost, zero rendering overhead
Node data tagging
Click model nodes to bind business data, JSON import/export, essential for industrial visualization
Model diagnostics
Auto-scan on import: duplicate vertices, oversized textures, missing normals at a glance
Batch processing
Process a whole folder at once, pause / resume / cancel anytime, live progress
7 formats conversion
FBX / OBJ / STL / DAE / PLY to GLB in one click, textures auto-embedded
Pro viewer
Section view, animation preview, sunrise/sunset simulation, free screenshots & recording
Fully offline
No internet, no registration, data stays local — safe for confidential projects
Dual-Engine Comparison
Draco or Meshopt?
Not sure which one? Go with Meshopt — better compression, auto-fallback to Draco on failure.
- Up to 90% compression, mature and stable
- Native support in Three.js / Babylon.js / model-viewer
- JPEG / WebP / KTX2 texture output
- Levels 1–10 + fine-grained quantization
- Geometry-only, no vertex cache optimization
- Better compression plus vertex cache optimization
- Integrated BasisU textures (ETC1S / UASTC)
- WebGPU-friendly, faster load & decode
- Auto-switch to Draco, seamless fallback
- Not yet supported in Babylon.js / model-viewer
