Your files stay local
Viewing, measuring and converting run in your browser. Unless you publish a share link or save a model to your workspace, your file never leaves your device.
Security
Designed so your data stays yours
Security at 3DViewerConvert starts with a simple architecture: almost everything happens in your browser, so there is less to protect on our side.
Encryption in transit & at rest
All traffic is served over TLS. Shared models are stored encrypted at rest on Cloudflare R2 and are only accessible through unguessable share IDs.
Secure authentication
Accounts are handled by Supabase Auth with Google OAuth or email/password. We never store your password and sessions rotate with every request.
Short processor list
We keep third-party data processors to a minimum: Cloudflare (edge + R2 storage) and Supabase (database & authentication). No trackers, no ad networks.
Reporting a vulnerability
