About This Tool

GLB files often pack textures into a single container. This page reads and exports those embedded textures, making it easy to reuse color, normal, roughness, and other channels in your own projects.

Format Information

Input format

Extension:
glb
Full Name:
GL Transmission Format Binary (glTF 2.0)
Type:
3D Model
Format:
GLB
Tools:
Three.js、Babylon.js、Blender
Open With:
3D Model Viewer、GLB Viewer
Description:
GLB is the binary glTF 2.0 format from Khronos Group, packing meshes, materials, textures, and animations into one file. It is the standard for Web 3D and AR/VR, used by Three.js, Babylon.js, model-viewer, and e-commerce previews for self-contained, reliable distribution. GLB supports PBR materials, skeletal animations, Draco and Meshopt compression, suitable for web, AR, and cross-software use. However, it loses CAD parametric history when tessellated from STEP or native CAD. For 3D printing, use STL or 3MF as slicers cannot import GLB.

Notes:

  • Some 3D printing slicers cannot directly import GLB files
  • Not suitable for CAD parametric editing

Supported Features:

  • Single self-contained binary file
  • PBR material support (base color, metallic, roughness, normal maps)
  • Skeletal animation, skinning, and morph targets
  • Draco mesh compression and KTX2 texture compression
  • Multi-mesh nodes and scene hierarchy

Output format

Extension:
png
Full Name:
Extracted Textures and Materials
Type:
Image / Material Package
Format:
PNG / Material GLB / ZIP
Tools:
Photoshop、Blender、GIMP
Open With:
Image Editor、3D Model Viewer
Description:
Textures are exported as lossless PNG at original resolution. Materials can also be exported as mesh-free GLB (containing only material definitions and textures) for reuse as a material library, or multiple textures/materials can be packaged as a ZIP for download.

Notes:

  • KTX2-compressed textures are converted to PNG on export
  • Material GLB contains only materials and textures, no mesh geometry
  • Multi-select packs materials as ZIP with one GLB per material

Supported Features:

  • PNG download per texture
  • Mesh-free material GLB export
  • ZIP package for multiple textures or materials
  • Original resolution preserved

Frequently Asked Questions

View all FAQs
Q

What output format is used?

A

Extracted textures keep their original embedded format. PNG is the default, and JPEG is also available. The tool does not recompress or transcode, so the original resolution and dimensions are preserved exactly.

Q

What if no textures are extracted?

A

Missing textures usually mean the GLB file didn't embed any images, or they are externally referenced. Make sure your GLB contains embedded textures; this tool only reads internal data.

Q

Will the resolution be reduced?

A

No. The tool reads the raw texture data directly from the GLB file, so the extracted images keep the exact same resolution and quality as the originals. No recompression or scaling occurs.

Q

How are extracted texture files named?

A

Textures are extracted using their original names inside the GLB, preserving suffixes like '_baseColor' or '_normal'. If multiple textures share the same name, they are numbered sequentially to avoid overwriting.

Q

Are GLB textures always embedded, or can they be external?

A

GLB is a self-contained binary format, so in practice all images are packed inside the file and this tool reads them directly. External references are theoretically possible but very rare; if a GLB yields no textures, it simply contains none.

Q

Can I re-embed the extracted textures into a GLB after editing?

A

Yes. After editing the extracted images, use the GLB Texture Compression tool to re-encode and re-embed the maps (WebP/JPEG/PNG/KTX2) into a single GLB. Alternatively, assign the edited maps to the model in Blender and export a new GLB.
