FBX Viewer
Open an FBX model, rotate it and inspect its geometry. Viewing local files happens in your browser. Switch to Optimize, Convert or Animations without importing the model again.
See what is actually in the file.
The scene graph, every material and texture, their estimated RGBA8 texture memory, the draw calls, the skeleton and every clip. Draco, Meshopt and KTX2 files open too, and nothing is uploaded.
Exported by Khronos glTF Blender I/O v4.3
Open your model
Drop the .fbx file together with any external texture images. You can also provide a ZIP containing the model and its companion files. Embedded textures travel inside the FBX.
What to check
Inspect the scene, materials and skeleton. When the file contains supported animation clips, open Clips in file to preview them; the Animations tool is for working with a rigged character.
FBX exporters differ. Missing texture files, unsupported materials or animation features can change the result. Compare the browser preview with your source application before converting.
Keep working on the same model
Inspect first, then use the tool buttons above to optimize geometry, check export readiness or work with animations. The current model stays open. AI operations may require an account and credits; opening and inspecting the file is free.
