Geometry payload
Vertex and triangle counts often dominate generated GLB size and runtime cost.
Decimate or remesh before applying compression.GLB optimizer
Before you compress or publish a generated GLB, inspect what is making it heavy. Use the viewer to identify geometry, materials, textures, animation data, and scale issues.
Inspection checklist
Open the exported file before it reaches your viewer, game engine, product page, or slicer. The checker helps you catch common model issues early.
Vertex and triangle counts often dominate generated GLB size and runtime cost.
Decimate or remesh before applying compression.Large embedded textures can make an otherwise simple GLB slow to load.
Resize textures and consider WebP or KTX2 workflows.Many materials can slow rendering even when file size looks acceptable.
Merge materials or bake into a single atlas where possible.Optimization order
Compression helps, but it does not fix a bad source asset. First identify the largest cost, then optimize the right part of the model.
Geometry reduction
Texture resizing
Material consolidation
Web delivery
A web-ready GLB should have a reasonable file size, bounded texture memory, few material slots, and a scale that works in your viewer.
Target mobile GPU limits
Avoid oversized textures
Check the final compressed file again
Choose the right local tool
Every route keeps files local in the browser. Pick a focused tool if you already know the format.
No. It inspects the file and shows what needs optimization. Use tools such as Blender, gltf-transform, or engine import settings to apply changes.
Draco can reduce geometry size, but inspect the file first. If textures or material count are the main problem, Draco alone will not solve it.
It depends on the experience, but smaller is usually better for public pages. Inspect triangle count, texture size, and material count before setting a target.
