FBX Viewer — Open FBX Files Online
View, inspect and convert FBX models right in your browser. Meshes, materials, textures and animation, with nothing to install and nothing uploaded.
Your FBX file is read and rendered entirely by your own browser. It is never uploaded to A23D, never stored, and never seen by anyone but you.
How to open a FBX file
No account, no plugin, no upload. Three steps and your model is on screen.
Drop in your file
Drag the .fbx onto the viewer, or click to browse. If the model references separate material or texture files, drop the whole folder or a .zip so everything resolves.
Inspect the scene
Orbit, pan and zoom to look around. The inspector lists every mesh in the hierarchy with its triangle count, and reports the bounding box so you can sanity-check scale.
Convert or capture
Save a PNG of the viewport, or download the model converted to GLB, OBJ, STL, PLY or USDZ — all without the file leaving your browser.
What is an FBX file?
FBX (Filmbox) is an interchange format owned by Autodesk. It began life at Kaydara in 1996 as the native format of a motion-capture application, passed to Alias, and has been Autodesk property since 2006. Its purpose is moving complete scenes between applications that share no common file format — which is why it turns up everywhere from Maya and 3ds Max to Unity, Unreal Engine and Blender.
Unlike a geometry-only format such as STL or OBJ, an FBX file carries a whole scene graph. A single .fbx can hold meshes, a node hierarchy, materials, texture references, cameras, lights, skeletal rigs, skinning weights, blend shapes and multiple animation takes. That richness is exactly why it became the default hand-off format for games and VFX pipelines.
FBX comes in two encodings. Binary FBX is compact and by far the most common. ASCII FBX is a readable text variant, easier to diff and debug but substantially larger. Both use the same .fbx extension, so you often cannot tell which you have without opening it — this viewer reads both.
The format is versioned, and the version matters more than most people expect. FBX 7.x (2011 onward) is what modern software reads and writes. Files written in the older 6.x structure use a fundamentally different layout that current parsers — including this one, Blender's importer and Unity's — cannot open. If a file refuses to load anywhere, its age is the first thing to check.
Textures are FBX's most common source of confusion. The format supports embedded media, where images are packed into the file itself, and referenced media, where the file merely stores paths to images sitting beside it. Referenced textures are the default in most exporters, which is why an FBX so often arrives grey: the maps were never in the file to begin with.

FBX viewer FAQs
The questions we get asked most about opening FBX files.
Is my FBX file uploaded to a server?
No. The file is read by your browser and rendered on your own graphics card. It is never transmitted to A23D or anywhere else, which also means there is no file size cap imposed by an upload and nothing to delete afterwards.
Why does my FBX model appear grey with no textures?
Most FBX exporters reference textures as separate image files rather than embedding them, so a lone .fbx contains only paths to maps that are not there. Drop the entire folder, or a .zip of it, so the images are available alongside the model. Alternatively, re-export from your 3D application with the embed media option enabled.
Can this viewer play FBX animations?
Yes. If the file contains animation takes, a timeline appears below the model with a clip selector, play and pause, scrubbing and playback speed. Skeletal animation and blend shapes both play back.
My FBX will not open. What is wrong?
The most common cause is an old file. FBX changed structure at version 7.0 in 2011, and files written before that cannot be read by modern parsers, including Blender and Unity. Open it in the application that produced it and re-export as FBX 2013 or newer. A truncated or partially downloaded file will also fail.
Can I convert FBX to GLB or OBJ here?
Yes. Once the model is loaded, use Convert to and pick GLB, OBJ, STL, PLY or USDZ. The conversion happens in your browser, so the file still never leaves your machine. GLB is the best choice for web and AR because it packs geometry and textures into one file.
Why is my model enormous or microscopic?
FBX does not reliably record its units, and exporters disagree: FBX usually means centimetres, glTF means metres. The camera auto-frames whatever it finds so the model always fills the view, and the inspector lets you say what one unit represents to read real-world dimensions.
Does it work on a phone or tablet?
Yes, on any modern browser with WebGL. Rendering uses the device GPU, so very heavy scenes will run better on a desktop machine. Large FBX files may also strain a phone memory limit.
