No software to install. No file size limit. No account required.

5 formats. 0 config.

STL, OBJ, GLTF, GLB, and 3MF — format is detected automatically from file content. Drop it and it works.

AR on any phone

iPhone uses Apple Quick Look — no install. Android uses WebXR with real-world lighting and dimension labels.

Adapts to your device

Flagship phone or old budget device — rendering quality adapts automatically. No crashes on large models.

Embeddable

One script tag. One custom element. Add a 3D viewer with AR to any website — Shopify, WordPress, custom.

For 3D printing

Drop your STL, check scale in AR before printing. See real-world dimensions in millimetres overlaid on the model.

Share by link

Paste any public model URL — geometryviewer.com/?url=… — and share the link anywhere. The viewer opens it instantly, no download required.

AR

Place any model in your room

Tap "View in AR" and the model appears on your floor, table, or shelf at real scale. Check proportions before printing. Show clients how a design looks in context. No app download. It's all in the browser.

iOS Safari → Apple Quick Look — native gestures, instant placement

Android Chrome/Edge → WebXR — light estimation, mm/cm labels, pinch to scale
