GLB Optimizer

Optimize 3D GLB models for faster loading. Reduce file sizes by up to 70% with mesh compression and Draco encoding.

SingleBatch

How It Works

1
Upload Your GLB File

Upload a GLB/glTF 3D model from your 3D software, AI generator, or existing asset library. Anonymous uploads support files up to 4 MB; signed-in users can optimize files up to 100 MB.

2
Configure Optimization

Choose compression options: Draco mesh encoding, texture format (WebP, AVIF, JPEG), texture size limits, and geometry simplification.

3
Download Optimized Model

Get your optimized GLB file with reduced file size while maintaining visual quality. Save to Sirv CDN for fast global delivery.

GLB Optimization Features

Draco Compression

Industry-standard mesh compression reduces geometry data by 80-90% with minimal visual impact. Compatible with Three.js, Unity, and all major viewers.

Texture Optimization

Convert textures to modern formats (WebP, AVIF) with Sharp for high-quality compression. Resize large textures to reduce file size.

Geometry Simplification

Reduce polygon count with meshoptimizer's simplification algorithm. Adjustable ratio preserves detail where it matters.

Deduplication

Remove duplicate vertices, materials, and textures. Prune unused data that bloats file size without visual benefit.

Mesh Instancing

Enable GPU instancing for repeated geometry. Reduces draw calls and improves rendering performance.

Vertex Welding

Merge nearby duplicate vertices to reduce mesh complexity while preserving smooth normals and UVs.

Scene Graph Optimization

Flatten node hierarchy and join separate meshes to reduce scene complexity and improve load times.

Credit-Based Processing

Signed-in optimizations use 2 credits per model, with the same credit accounting and retry safety as other AI tools.
