TERMS OF USE · UPDATED SEPTEMBER 26, 2026

Use with care.
Keep your original.

The service

gltfpack Online is an independent interface for optimizing GLB files. It is not affiliated with or endorsed by the meshoptimizer project. By using this service, you agree to these terms.

Your files and permissions

You retain your rights to the files you upload. Only submit content that you own or have permission to process. You permit the service to temporarily receive, process and return your files for the requested optimization. Uploading does not transfer ownership to us or make your model public.

Temporary processing

This is not a backup or storage service. Keep a separate original. Results expire 60 minutes after upload and may become unavailable during failures or outages. See File privacy for deletion, access tokens and operational data handling.

Responsible use and limits

Do not use the service for unlawful content, to disrupt other users, to bypass limits, or to attempt unauthorized access to tasks or systems. Uploads are limited to 50 MB and processing to 120 seconds. Requests may be rejected when capacity or rate limits are reached. Access may be restricted to protect the service.

Check every result

Optimization may alter geometry, textures, precision, animations and scene structure. We do not promise smaller files, error-free results, compatibility with a particular application or uninterrupted availability. Verify outputs before publishing or relying on them. The service is provided as available; these terms do not exclude rights or protections that applicable law does not allow to be excluded.

Third-party software and changes

Open-source components remain subject to their respective licenses. The licenses page identifies key components and links to their notices. Those licenses do not grant rights to models uploaded by users. Features, limits and these terms may change; the current terms are published on this page.
