Step by step, and if something goes wrong
Steps
- Add one or more 3D models.
- Choose the format to convert to, and the orientation and size options if you need them.
- Select Convert, then download each file or all of them as a ZIP.
If something goes wrong
- STL and PLY files from CAD and 3D printing usually have Z pointing up. Choose Stand upright when converting them to GLB or USDZ.
- STL files have no units. For AR, choose Millimetres to metres if the model was made for 3D printing, or it will appear 1,000 times too big.
- STL, OBJ and PLY keep the shape only. GLB and USDZ also keep colours and textures.
- STL, OBJ, PLY, GLB and FBX files are opened on this device. Nothing is uploaded.
- GLB files must be self-contained. Files that use Draco or meshopt compression aren’t supported yet.
- FBX textures stored as separate files aren’t included; the shapes still convert.
