How to choose a workflow
Privacy by default
A local tool keeps model files on your device. Hosted tools can be a better fit when you specifically need an API or managed processing, but require uploading the asset.
Test your own assets
File-size reduction and visual impact depend on the model. Compare output in your target engine and validate extensions such as Draco, WebP, or KTX2 before shipping.
OptimizeGLB is a good fit when
- You want model files to stay on your device
- You want to compare results before downloading
- You do not need an account or hosted processing
Consider another workflow when
- You need a hosted API or server-side automation
- Your files exceed the memory available to the browser
