Open any 3D file without installing anything
Opening a 3D model usually means launching Blender, buying a CAD seat, or uploading your file to a service that keeps a copy. This free online 3D model viewer removes all three problems: drop in a file and it renders instantly in your browser, with nothing sent anywhere.
The viewer reads the formats you actually receive from clients, marketplaces and scanners:
- glTF and GLB — the standard for web and real-time 3D, including Draco and Meshopt compressed geometry
- OBJ — with optional
.mtlmaterial files - STL — the 3D printing workhorse, both ASCII and binary
- PLY — meshes and coloured scan output
- FBX, COLLADA (DAE) and 3DS — the classic DCC interchange formats, animations included
- USDZ and USD — Apple Quick Look and AR assets
- 3MF and AMF — modern 3D printing containers
- Draco, OFF, VRML and VTK — research and pipeline formats
- XYZ, PCD, LAS and LAZ — LiDAR and photogrammetry point clouds
What you can do with it
Check a file before you buy or ship it. Marketplace previews are rendered by the seller. Load the actual file and see the real triangle count, the real material list, and whether those textures are actually there.
Diagnose a broken export. Switch to normals shading to spot inverted faces, or to the UV checker to catch stretched and mirrored UVs. Wireframe mode reveals hidden density where a subdivision modifier was left on.
Confirm scale before printing. The stats panel shows the exact bounding-box dimensions in the file's own units, so you know whether that STL is 3 cm or 3 m before you slice it.
Inspect a rigged asset. Animation clips are listed with their names and durations, and you can play them back one at a time.
Explore a point cloud. LAS and LAZ scans load with their RGB or intensity colouring, subsampled automatically so even multi-million-point datasets stay smooth.
How to use it
- Drop your model onto the file picker, or click to browse.
- If it is a
.gltfwith external.binand texture files — or an.objwith an.mtl— add those in the second picker so materials resolve correctly. - Orbit with the left mouse button, pan with the right, zoom with the scroll wheel.
- Use the toolbar to toggle the grid, axes, wireframe and auto-rotation.
- Pick a standard view (front, top, isometric…) to line up a consistent angle.
- Click Download PNG to save a high-resolution snapshot with a transparent or solid background.
Tips
- Click any row in the hierarchy panel to zoom the camera onto that specific mesh — the fastest way to find a stray object sitting a kilometre from the origin.
- If a model appears black, it probably relies on textures that were not included; the material list will show zero textures.
- Very large files are limited by your available memory, not by an upload cap. A 500 MB GLB will open if your browser has the RAM for it.
Privacy
Every byte stays on your machine. The viewer uses WebGL and the browser's own file APIs — there is no server round trip, no temporary storage and no account. That makes it safe for NDA'd client work, unreleased game assets and proprietary CAD conversions.
