Open a GLB file (and use it in Blender)
GLB is the single-file version of glTF, the common format for 3D models on the web, in AR and from AI 3D tools. To just look at a GLB, open it here: turn it with a finger or mouse and zoom in, with nothing to install. To edit it in Blender, use File → Import → glTF 2.0 (.glb/.gltf) in Blender.
STL viewer for 3D printing
Check an STL before sending it to a 3D printer: see the model from every side, and use Measure to check its size box, the distance between two points, and its area and volume.
Works on
Any modern browser on Windows, Mac, Android and iPhone, plus the free Android app. Most models are drawn right in your browser; Blender (.blend) files are converted on our server first and then deleted.
Privacy
Your file is sent over an encrypted (HTTPS) connection to our server only to make the preview or the export you ask for, and it is deleted automatically when that is done. Opening files needs an internet connection. See the privacy policy.
