Model Vertex Compression
Reduce polygon count and apply Draco encoding to make your 3D models smaller and faster to load. Supports all common 3D formats.
About This Tool
This comprehensive vertex compression tool uses glTF-Transform to optimize your 3D models. It applies mesh simplification (quadric-based error metrics) to reduce polygon count and Draco encoding for efficient data compression. All processing happens locally in your browser with no server uploads required.

Frequently Asked Questions
What is the difference between this tool and format-specific tools?
This general-purpose tool accepts any supported 3D format. Format-specific tools are optimized for a single input format with tailored settings and SEO.
How much can I reduce the file size?
Typical reduction is 50-90% depending on model complexity. High-polygon models with Draco encoding achieve the best compression ratios, often reducing files to 10-20% of original size.
Will compression affect visual quality?
Mesh simplification reduces geometric detail. A ratio of 0.5 retains 50% of polygons which is often imperceptible at normal viewing distances. You can preview results in real-time.
What formats are supported for input?
GLB, GLTF, OBJ, FBX, STL, and PLY formats are supported. Non-GLB formats are automatically converted to GLB during processing.
Can I use compressed models in game engines?
Yes! Most modern game engines (Unity, Unreal) and WebGL frameworks (Three.js, Babylon.js) support Draco-encoded GLB/GLTF files natively or via plugins.
