Free online STL viewer

Check an STL file before slicing or printing, directly in your browser. The same viewer also opens GLB, glTF, OBJ and PLY files.

Drag and drop a 3D file here, or choose a file

Supported formats: GLB, glTF, OBJ, STL, PLY.

Files are processed entirely in your browser and never leave your device. For textured models use .glb, which packs geometry and textures into a single file.
