Open any 3D file in your browser
GLB, OBJ, STL, 3MF, FBX, PLY or STEP. Drop it in and explore it. The file never leaves your machine.

How to open a 3D file online
- Drop your .glb or .gltf or .obj or .stl or .3mf or .fbx or .ply or .step or .iges file onto the viewer, or click to browse for it.
- The file is parsed on your own machine and rendered straight away.
- Explore it from any angle. On a phone, use the AR button to place it at real size.
One viewer for every common 3D format
Most free viewers open one format. That is fine until a client sends a STEP, a game asset arrives as FBX and your scanner writes PLY. This viewer reads the extension of the file you drop and uses the right reader for it, all inside your browser.
| Format | Usually from | Colour | Unit |
|---|---|---|---|
| GLB, glTF | Web, AR, Shopify, game engines | Yes, inside the file | Metres |
| OBJ | Any 3D editor | In a separate .mtl | None stored |
| STL | 3D printing, CAD export | No | None stored, usually mm |
| 3MF | Slicers: Bambu Studio, PrusaSlicer, Cura | Yes | Stored, usually mm |
| FBX | Maya, 3ds Max, Blender, Unity, Unreal | Yes, if embedded | Stored, usually cm |
| PLY | 3D scanners, photogrammetry | Per vertex | None stored |
| STEP, IGES | CAD: SolidWorks, Fusion, Onshape, FreeCAD | Per body | Stored, shown in mm |
What you can check
- Shape and surface from every angle. Drag to spin, scroll or pinch to zoom.
- Real size as width, depth and height, in the unit you choose.
- Triangle count and file size, to judge if a model is light enough for the web or AR.
- A PNG screenshot of the current view, on a white background.
- AR on a phone, at real size.
STEP files open without CAD software
STEP is the hardest of these formats to open, because it stores exact curved surfaces, not triangles. This viewer runs OpenCascade, the open-source geometry kernel behind FreeCAD, compiled to WebAssembly. It downloads about 7.6 MB the first time you open a CAD file, and then turns the surfaces into a smooth mesh on your machine.
Your file never leaves your browser
This tool is JavaScript running on your own machine. Your file is read into memory, processed there, and gone when you close the tab. It is never sent to us, so there is no upload, no queue, no retention period, and no account to create. You can disconnect from the network after the page loads and it will still work.

Your first model is $2, refunded in full within 14 days if you do not like it. Try it with a sample photo
Frequently asked
Which 3D file formats can I open?
GLB, glTF, OBJ, STL, 3MF, FBX, PLY, STEP and IGES. Drop any of them here and the viewer picks the right reader from the file extension. That covers web and AR models, print files, game and animation files, 3D scans and CAD parts.
Is my file uploaded?
No. The file is read and rendered in your browser, on your own machine. Nothing reaches our servers, and there is no account, email or file limit.
Why is my model grey?
Because the file has no colour in it, or keeps its textures in separate files. STL and PLY scans often carry geometry only. OBJ stores materials in a .mtl file beside it, and some FBX files point at textures on the author's disk. GLB and 3MF carry their colour inside the file.
How do I check the size of a model?
The bar under the viewer shows width, depth and height. GLB and glTF are in metres by their specification. STL, OBJ, PLY and 3MF store no unit, so pick millimetres, centimetres, inches or metres from the menu. The choice also sets the size in AR.
Can I view the model in AR?
Yes, on a phone. Open this page on Android or iPhone, load the model and tap the AR button to place it in your room. Very heavy meshes, such as dense scans, may be too large for a phone to show in AR.
