FILE HANDLING
File privacy
When you choose a file, the preview runs in your browser. Clicking Optimize uploads the model to our server for processing with gltfpack.
Temporary processing
Input and scratch files are removed when processing completes or fails. Successful output is available until 60 minutes after upload. The cleanup worker removes expired files, normally within a few seconds; cleanup resumes after service outages. Interrupted uploads are cleaned after five minutes. Task metadata expires with the task.
Access and limits
Each task has a random access token. Keep it private. We accept one embedded-resource GLB up to 50 MB, process for up to 120 seconds, and limit output to 100 MB. Files are not published in a gallery or used for training.
Operational data
We keep aggregate daily visit, accepted upload, task success/failure and result-fetch counts for up to 90 days. They do not contain model contents or original filenames. Temporary hashed network identifiers are used for rate limiting and expire after their rate window. Nginx access logging is disabled for this site. Nginx error logs are configured for daily rotation with 14 rotated files retained. We use Clicky for website traffic analytics. Clicky receives browsing and device information. See its privacy policy for details.
Check before using the result
Optimization may change scene structure, precision and animations. Custom extensions may be discarded. Keep your original file and verify the output in your target application. This is an independently operated interface to the MIT-licensed gltfpack engine.
