Part of the glTF Transform project.

GitHub: https://github.com/donmccurdy/glTF-Transform
Project Documentation: https://gltf-transform.dev/
CLI Documentation: https://gltf-transform.dev/cli

Quickstart

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

npm install --global @gltf-transform/cli

List available CLI commands:

gltf-transform --help

Optimize everything all at once:

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 or Meshoptimizer:

# 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, or improve VRAM usage and performance with KTX2 and Basis Universal:

# 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

... and much more.
