Loading viewer
Open a GLB, glTF, OBJ, STL, PLY, or FBX file in the browser without uploading it. Drop the file here and the viewer for its format opens; each format has its own viewer page.
Updated August 2026
A reader for six mesh formats, running on your device.
An online 3D viewer opens a mesh file in the browser so you can orbit, zoom, and check it before you convert, print, or hand it on. 3DLogo.io has one viewer per format because each format carries different data: GLB and glTF keep materials and textures, OBJ and STL are geometry, PLY carries scan colour per vertex, and FBX is a desktop export that opens read-only. Drop a file here and the matching viewer opens; nothing is uploaded.
Three steps, no account. The file stays in this tab.
1
Drag a .glb, .gltf, .obj, .stl, .ply, or .fbx onto the panel. The viewer for that extension opens; or choose it from the table below.
2
Drag to orbit, scroll to zoom, press F to frame. Materials show where the format carries them; geometry-only formats render white.
3
Every viewer links to its conversion pair. To make a new mesh, use the logo editor for a mark or Generate for a photo or prompt.
Match the extension. Each row is a separate viewer page with its own notes on what the format keeps and drops.
| Viewer | Shows | Skips | Convert |
|---|---|---|---|
| GLB viewer | PBR materials, textures, and clips in one binary file. | Nothing; GLB is the web format the editor and Generate write. | GLB to OBJ |
| glTF viewer | The JSON form of the same scene, with external buffers and textures. | Sidecar files must be present; a lone .gltf shows geometry only. | glTF to GLB |
| OBJ viewer | Geometry and UVs from a Wavefront mesh. | Materials; the MTL file is not read. | OBJ to GLB |
| STL viewer | The triangle hull a slicer will see. | Colour and materials; STL has none. | STL to GLB |
| PLY viewer | Scan and point-cloud meshes, with vertex colour when present. | Textures; PLY carries colour per vertex, not images. | PLY to GLB |
| FBX viewer | A DCC export, read-only, so you can check it and convert out. | Writing FBX; convert to GLB or OBJ instead. | FBX to GLB |
A file from the 3DLogo.io editor or Generate is a GLB. Desktop modelling tools usually export OBJ or FBX; 3D printers want STL; scanners produce PLY. If the extension is not one of these six, export GLB or FBX from the app that made it and open that.
Every viewer reads the file with the browser and renders it on your GPU. Nothing is sent to a server and no account is needed, which is why a client file, a scan, or an unreleased product can be checked here. The limit is 80 MB per file.
Match the extension: .glb opens in the GLB viewer, .gltf in the glTF viewer, .obj in the OBJ viewer, .stl in the STL viewer, .ply in the PLY viewer, .fbx in the FBX viewer. Other extensions such as .blend, .usdz, .3ds, or .dae are not supported; export to GLB or FBX from the source app first.
No. Each viewer reads the file in your browser tab and renders it on your device. Nothing is sent to a server, and no account is needed.
Each viewer links to the matching conversion pair. The 3D converter writes GLB, glTF, OBJ, STL, and PLY from any of the six formats, also on the device.
Files up to 80 MB. Larger scenes may load but render slowly on laptops; reduce the mesh or split the scene first.
The viewers are free. The logo editor extrudes a mark into a GLB; Generate builds one from a photo or prompt.
One page per format, each with what the file keeps and drops and the matching conversion. To write a different format, use the 3D converter.
