glTF Transform is an SDK for reading, editing, and writing glTF 2.0 3D models in JavaScript and TypeScript, running on both Web and Node.js. It provides a scripting API, extension support, common optimization functions, and a CLI for inspecting, bundling, splitting, and optimizing glTF/GLB files.

Use cases

• optimize glTF models for web delivery
• compress glTF meshes with Draco or Meshopt
• convert textures in glTF files to WebP or KTX2
• batch process 3D model assets in a build pipeline
• inspect and validate glTF files from the command line
• programmatically edit scene graphs, materials, and animations
• split or merge glTF scenes and deduplicate geometry
• build custom glTF extensions in TypeScript

When to choose

• you need reproducible, lossless, scriptable edits to glTF 2.0 assets
• you want to optimize 3D models for web or mobile delivery in CI
• you're building web apps that read or transform glTF at runtime
• you need CLI tooling to inspect, validate, and optimize GLB files

When to avoid

• you need artistic modeling changes like sculpting or UV unwrapping — use Blender or a DCC tool instead
• you work with formats other than glTF 2.0 (e.g., FBX, OBJ)
• you need a visual scene editor rather than programmatic transforms
