GLB workflow · preview, edit, optimize

Free GLB editor online for game-ready assets.

Upload, preview, inspect, resize, optimize, and prepare GLB or GLTF models for web games, Three.js, Unity prototypes, Roblox-style projects, and playable scenes.

High-intent use cases.

Preview GLB before import

Inspect geometry, scale, materials, texture paths, and file size before using the model in a game project.

Fix scale and rotation

Normalize model dimensions and orientation so a prop or character fits your scene.

Optimize for web games

Reduce unnecessary weight and prepare a lighter GLB for browser loading.

Generate matching props

When one GLB works stylistically, create similar assets or an asset pack with AI as a helper.

AI generation is the helper.

Use generation when the edited asset needs a missing prop, a similar variant, or a matching pack. The main conversion point remains edit → optimize → export → playable.

Generate matching pack

Promise boundary.

Use “prepare”, “optimize”, and “prototype-ready” unless the full engine import/export path is verified. Avoid overclaiming production-ready or platform-ready results.

FAQ

Can I edit GLB files online without Blender?

This page is positioned for fast online preview, edit, optimization, and export workflows before opening a full DCC tool.

Is GLB better than FBX for web games?

GLB is usually easier for browser and Three.js workflows because geometry, material metadata, and textures can travel in one compact file.

Where does AI generation fit?

Use AI after previewing or editing when you need a missing prop, similar asset, or matching pack.

Upload, preview, edit, optimize, then use it.

Upload or import

Start from GLB, GLTF, FBX, OBJ, ZIP, or an AI-generated model when supported.

Preview and inspect

Check scale, geometry, material preview, texture expectations, and file weight before changing anything.

Edit / optimize / convert
