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.

What this tool does

How it works

  1. 01

    Drop your model

    Drag the file onto the page or pick it from your computer. It loads as a local blob — it never gets uploaded.

  2. 02

    Explore and measure

    Orbit with the mouse, toggle wireframe or clay, and measure real millimeters between any two points.

  3. 03

    Capture or convert

    Export a PNG of your framing, or jump straight to the converter if you need another format.

Frequently asked questions

Do my files get uploaded to a server?

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.

How large a file can it handle?

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.

Why are measurements in millimeters?

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.

Can I see textures and colors?

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.
