Convert 3DM files to GLB in seconds. Geometry, UVs and materials are carried over where GLB supports them, and the model lands the right way up.
Drop it on the converter above or click browse. It opens in your browser, so nothing is uploaded.
GLB is already selected. You can switch to any other output from the menu.

3DM is the native file of Rhino, used widely in industrial, jewellery and architectural design. It stores NURBS surfaces, SubD objects, meshes and block instances.
GLB is the single-file binary version of glTF, the open standard for 3D on the web. It packs geometry, materials and textures into one compact file that browsers, Android AR and most viewers load directly.
Rhino saves a display mesh for every surface it has shown in shaded view. We use those meshes. If a file was saved with "Save Small", open it in Rhino, switch to shaded view and save it again.
Colours and texture coordinates are carried over when GLB supports them. Texture images are kept for formats that can hold them.
No. 3DM and GLB may use different "up" directions, and we rotate the model so it stands the same way in your software.
