3D Converter
Convert a 3D model from one file type to another in seconds. Drop in an STL, OBJ, PLY, OFF, 3MF, glTF or GLB file, pick the format you need, and download the converted model straight to your device. The conversion happens inside your own browser, so your designs are never uploaded anywhere.
Choose your 3D files
Drag files here, or browse your device. Everything is converted inside your browser — your models are never uploaded to a server.
Accepted files: .stl .obj .ply .off .3mf .glb .gltf · up to 200.0 MB each
STEP, IGES and FBX are not converted yet — they need a CAD engine we have not shipped, so they are not offered here.
Which file types can I convert?
The converter reads and writes .stl .obj .ply .off .3mf .glb .gltf. Every one of these can be turned into any of the others, so you can move a model between modelling software, a slicer and a web viewer without reinstalling anything.
Is my model private?
Yes. Your files stay on your own device. Nothing is sent to us, stored by us, or shared with anyone else, and files disappear as soon as you close the page.
What happens next?
Once you have the file type you need, open the VANTARA 3D slicer to prepare your model and create printer-ready G-code, or read how VANTARA works from model to finished print.
