Using the tools
STL File Viewer provides free, browser-based utilities for viewing and converting 3D files. You may use them for personal and commercial work. No license is granted to the models you process — your files remain entirely yours, and entirely on your device.
No warranty
The tools are provided "as is", without warranty of any kind. Conversion results, statistics and dimension readings are generated automatically and may contain errors; always verify critical output — especially before 3D printing or production use — with your own toolchain. We are not liable for any damages arising from use of the site.
Acceptable use
Do not use the site to attempt to disrupt service, bypass browser security, or process content you have no right to access. Since files never leave your browser, responsibility for the files you open rests with you.
Changes to the service
Tools may be added, changed or removed over time. These terms may also change; material changes will be reflected by an updated date on this page. Continuing to use the site after a change means you accept the revised terms.
