# glTF Transform CLI

> Command-line tool for inspecting, compressing and optimizing glTF/GLB 3D models, with Draco and Meshopt mesh compression, texture resizing and WebP/KTX2 compression; a single optimize command handles it all.

## Quickstart

Install the CLI, supported in Node.js LTS versions.

```bash
npm install --global @gltf-transform/cli
```

List available CLI commands:

```bash
gltf-transform --help
```

Optimize everything all at once:

```bash
gltf-transform optimize input.glb output.glb --texture-compress webp
```

Or pick and choose your optimizations, building a custom pipeline.

Compress mesh geometry with [Draco](https://github.com/google/draco) or [Meshoptimizer](https://meshoptimizer.org/):

```bash
# Draco (compresses geometry).
gltf-transform draco input.glb output.glb --method edgebreaker

# Meshopt (compresses geometry, morph targets, and keyframe animation).
gltf-transform meshopt input.glb output.glb --level medium
```

Resize and compress textures with [Sharp](https://sharp.pixelplumbing.com/), or improve VRAM usage and performance with KTX2 and [Basis Universal](https://github.com/BinomialLLC/basis_universal):

```bash
# Resize textures.
gltf-transform resize input.glb output.glb --width 1024 --height 1024

# Compress textures with WebP.
gltf-transform webp input.glb output.glb --slots "baseColor"

# Compress textures with KTX2 + Basis Universal codecs, UASTC and ETC1S.
gltf-transform uastc input.glb output1.glb \
    --slots "{normalTexture,occlusionTexture,metallicRoughnessTexture}" \
    --level 4 --rdo --rdo-lambda 4 --zstd 18 --verbose
gltf-transform etc1s output1.glb output2.glb --quality 255 --verbose
```
