Security

Your technical file is read and displayed on your device without a file-upload endpoint.

Built-in protections

• Browser-side processing for STL, OBJ and 3MF.
• No user file storage.
• No accounts or passwords.
• 3D dependencies pinned to specific versions and served by DropSee.
• HTTPS delivery with restrictive security headers.

Limits

Files up to 100 MB are supported. A malformed or unusually complex model may fail to open, but DropSee never modifies your original file.
