Does the glTF/GLB texture optimizer upload my model?

No. The model is parsed with glTF Transform and texture images are processed locally in your browser.

Can it optimize external texture files referenced by a .gltf?

This page optimizes embedded GLB textures and data embedded in uploaded glTF files. External texture references are reported but cannot be modified unless they are included in the file.

glTF/GLB Texture Optimizer

Inspect embedded model textures, recompress them in the browser, and export a GLB ready for web delivery or review.

Upload model

Use a GLB for the most reliable one-file workflow. Standalone glTF files are supported when texture data is embedded.

Drag and drop a .glb or .gltf file hereorChoose model file

- GLB files keep geometry and textures in one binary container.

- glTF files with embedded data URIs can be read and exported as GLB.

- External texture references are reported but not rewritten from a single-file upload.

Texture settings

These settings apply only to embedded PNG, JPEG, and WebP textures that can be decoded by the browser.
