3D model viewer FAQ
Is this 3D model viewer free?
Yes. Open as many models as you like, with no account, subscription or file count limit.
Which 3D formats can I open?
GLB and glTF (including Draco and Meshopt compressed), STL, OBJ, FBX, PLY and 3MF, and CAD files in STEP (.step, .stp), IGES (.iges, .igs) and BREP, up to 300 MB. A glTF that points to separate .bin or texture files needs to be a single .glb.
Are textures and animations shown?
Yes, for GLB, glTF and FBX: materials and textures are shown with realistic lighting, and the first animation plays. STL has no colour; PLY vertex colours are shown; OBJ materials live in a separate .mtl file, so OBJs are shown in grey. STEP and IGES parts are shown in the colours set in the CAD program.
What units are the dimensions in?
In the file’s own units. glTF and GLB are in metres; STEP, IGES and BREP are shown in millimetres, even if the file was saved in inches; STL, OBJ and PLY have no units, and most 3D printing files use millimetres.
Can I check a model before 3D printing?
Yes: check the size and triangle count here, then open the free GLB to STL converter to size it in millimetres, close holes and download an STL or 3MF.
Is my model uploaded?
No. The model is opened in your browser and never leaves your device.
