Embedded texture focus
Directs GLB users to the optimizer that reads embedded model images and reports texture inventory.
GLB texture workflow
Optimize textures inside GLB models
Use the browser-based glTF/GLB optimizer to inspect embedded textures, recompress image payloads, and download a compact GLB for web delivery.
Tool entry
Optimize the actual GLB asset
Open the real optimizer for model uploads, then use texture inspection or KTX2 encoding when your pipeline needs extra checks.
What this page covers
Smaller model downloads
Recompresses eligible embedded color textures to WebP or PNG without altering mesh geometry, animations, or non-color data maps.
Local model handling
The model is parsed and rebuilt in the browser; files are not uploaded to a server.
How to use it
Open the model optimizer, upload the GLB, adjust texture output settings, and download the optimized model.
- 01
Open the GLB optimizer
Start the real glTF/GLB texture optimizer from this page.
- 02
Upload the model
Choose a GLB or embedded glTF file and review the texture inventory.
- 03
Export the optimized GLB
Set format, size, and quality options, then download the rebuilt GLB.
FAQ
This page focuses on GLB model workflow needs and directs you to the interactive glTF/GLB optimizer where model parsing and texture recompression take place.
The optimizer processes GLB files and glTF files that embed texture data. External texture references are reported in the inventory, but if required external resources are missing, optimization refuses export to avoid writing an incomplete GLB.
The tool only rescales or recompresses eligible embedded baseColor and emissive images, without performing mesh simplification or animation optimization. Non-color data textures are not re-encoded, but because glTF document reading sanitizes unsupported references and reserialization occurs, byte-for-byte preservation across all materials and extensions is not guaranteed.
