FBX viewer online — open .fbx files, no upload
View FBX models in your browser without Autodesk software: binary and ASCII FBX, embedded textures, every mesh in the scene and its real dimensions. Measure, isolate parts, export to GLB or STL — the file never leaves your device.
Measure
Click a part to isolate it and see its own dimensions.
Dimensions & mass
Load a model to see its dimensions, volume, surface area and mass.
Cross-section
Measuring tips
- Snap is on by default — clicks land on the nearest corner or edge vertex, which is where CAD tessellations keep exact dimensions.
- Hole diameters: click three points spread around the rim (not in a line). The fit is a true 3D circle, so it works on tilted faces too.
- Units: STEP/IGES are read in millimetres from the file. Mesh formats carry no units, so the tool applies each format’s convention — if a model looks 10×, 25×, or 1000× off, switch File units rather than the display unit.
- Mass multiplies the closed-mesh volume by the material density — pick the right material, and expect open or hollow meshes to read low.
- X-ray + cross-section together show internal pockets, wall thickness and hidden holes.
Capabilities
What the fbx viewer does
- Opens binary and ASCII FBX (FBX 2011 / 7.x and newer) with embedded textures and materials, rendered with the same lighting model as the web.
- Scene parts list: each mesh with its name and colour — isolate one, read its dimensions, volume and mass, or view the whole scene with X-ray shading.
- Correct size: FBX units (centimetres by default, or the file’s own unit scale factor) are converted to millimetres automatically, with a one-click override.
- Point-to-point distance, angles and hole diameters with vertex snapping, plus cross-sections on any axis.
- Export any mesh as GLB for the web or STL for printing, download the parts CSV, or save a screenshot — or convert the whole file with FBX to GLB.
- 100% private — nothing is uploaded, no Autodesk account, no install, no watermark.
Process
How it works
- Drop the FBXDrag a .fbx file onto the viewer. Binary and ASCII variants are parsed locally, embedded textures included.
- Inspect the sceneBrowse meshes in the parts list, isolate one and read its dimensions and mass; switch to X-ray to see hidden geometry.
- Measure and exportMeasure features, cut a section, then export a mesh as GLB or STL — or convert the whole FBX to GLB for the web.
No Autodesk software
How to open an FBX file without 3ds Max, Maya or Unity
FBX is the exchange format of the game and animation world, but viewing one used to mean installing Autodesk’s FBX Review or a full DCC tool. Drop the file here instead: it is parsed in the browser, meshes and embedded textures appear in seconds, and the parts list lets you isolate a character, prop or building piece to check its size. Export a mesh as GLB to use it on the web, or as STL to 3D-print a game asset. For a complete conversion with materials, use FBX to GLB.
Scale
FBX units — why models import 100× off in Unity or Blender
FBX stores a unit scale factor, and the default unit is centimetres, while glTF and most web engines use metres and 3D printing uses millimetres. That mismatch is why an FBX character arrives 100× too big in one tool and 0.01× in another. This viewer reads the file’s unit scale factor and converts to millimetres, so the dimensions in the panel are the real-world size; if the exporter wrote the wrong unit, switch File units and the numbers update instantly.
Notes
Good to know
- Animations are not played; rigged characters are shown in their bind pose (static).
- Textures must be embedded in the FBX — references to external image files cannot be loaded from a single-file drop.
- FBX versions older than 7.0 (pre-2011) are not supported by the in-browser parser; re-export from the source tool.
- Units are converted from the file’s unit scale factor; files that omit it are read as centimetres.
FAQ
Questions, answered
How do I open an FBX file without Autodesk software?
Drop it here. The viewer parses binary and ASCII FBX in your browser and renders the meshes with their embedded textures — no FBX Review, 3ds Max, Maya, Blender or account required.
Is my FBX file uploaded to a server?
No. The file is parsed and rendered on your own device with WebGL — it is never uploaded, there is no account and no watermark. Close the tab and nothing is left behind.
Why are the textures missing?
The viewer loads textures embedded in the FBX. If your file references external images, re-export with “embed media” enabled, or convert the set to GLB.
Does it play animations?
No — the viewer shows the static bind pose. Use the turntable tools for animated previews, or convert to GLB and open it in the full editor.
How do I convert FBX to GLB?
Export a single mesh as GLB from the viewer, or use the FBX to GLB converter for the whole scene with materials.
What is the maximum file size?
Up to 300 MB. Very large meshes (millions of triangles) load on a desktop browser but can exceed the memory of a phone; the closed-mesh check is skipped above 1.5 million triangles to keep things responsive.
