Are my files uploaded to a server?

No. This conversion runs entirely inside your browser using your own device’s processing power. The file never leaves your computer or phone, which is why it also works when your connection drops.

What happens to the animation?

It is not carried into the OBJ, because OBJ stores one still shape. Convert to GLB instead if you need the animation to survive.

Does it read binary FBX as well as ASCII?

Yes, both. Most FBX files written in the last decade are binary and are handled without you having to know which you have.

Convert FBX to OBJ

Runs on your device · Your file never leaves your device.

FBX is what game engines and animation packages pass between each other, and it is awkward to open anywhere else. This turns one into an OBJ — a plain, ancient, universally readable mesh that almost any program will take.

An FBX often holds rigging and animation as well as shape. OBJ holds a single still pose and nothing else, so the animation does not come with it; if that is what you need, convert to GLB instead, which keeps the clips. The geometry and the material names come across either way.

The conversion runs on your own machine, which for a 3D file is the whole point: a model is usually a client’s product, a scanned property or something not yet announced. Nothing is sent to a server, so there is nothing to delete afterwards and nothing to take anyone’s word for.

How to convert FBX to OBJ

Drop the FBX file — and its companion files if it has any.
Check that OBJ is selected.
Press Convert.
Download the OBJ file.

Supported formats and limits

Input: FBX
Output: OBJ
Companion files: MTL and texture images are used when you add them
Keeps animation: No — the format cannot store it
Where it runs: In your browser; the model is never uploaded

Not for: Writing FBX — this reads FBX but cannot produce it. There is no browser-side FBX writer that would give you a file worth trusting.
