Universal 3D viewer
Open STL, OBJ, GLB, GLTF, PLY or 3MF models and explore them with real-millimeter measurements, wireframe and screenshots. Your file never leaves your device.

Drag the file onto the page or pick it from your computer. It loads as a local blob — it never gets uploaded.
Orbit with the mouse, toggle wireframe or clay, and measure real millimeters between any two points.
Export a PNG of your framing, or jump straight to the converter if you need another format.
No. The viewer runs 100% in your browser with WebGL: the file opens as a local blob and never leaves your machine. Once the page is loaded, it even works offline.
Models up to ~200 MB work fine on a modern machine. For very heavy meshes (millions of triangles), run them through the polygon reducer first.
STL, OBJ and friends don't store units; the 3D-printing convention is 1 unit = 1 mm. The viewer keeps the file's original dimensions and measures on them.
Yes: GLB/GLTF with embedded textures and PLY/OBJ with vertex colors display their original materials. STL has no color support — it shows in clay mode.
