OGEX Converter
FileFlip converts OGEX files into 14 other formats entirely inside your browser, using Assimp compiled to WebAssembly. The OGEX file is never uploaded to a server: it is read off your disk, converted on your own machine, and saved back by the browser. There is no file-size limit and no account to create.
How do I convert an OGEX file?#
- Drop your OGEX file onto the converter at the top of this page, or click it to pick one from your computer.
- Choose the format you want out of it. FileFlip downloads the engine that conversion needs, once, and your browser caches it.
- Conversion starts the moment you pick the format, and the result is yours to download. The work happens in this tab, so nothing is uploaded and nothing is queued.
Is it safe to convert OGEX files online?#
Yes, because nothing is uploaded. FileFlip converts OGEX files inside the browser tab you already have open, using WebAssembly builds of the same engines a desktop converter would install. Your file is read from your own disk into the page's memory, and no request carrying it is ever made.
You do not have to take that on trust. Open your browser's network panel, run a conversion, and you will see the engine come down and your file go nowhere. There is no upload, no server-side copy, no retention window, and no account tied to what you converted.
How FileFlip works lists every engine, its version and its download size, and shows how to check for yourself that nothing leaves your machine.

What is an OGEX file?#
An OGEX file is a text document in the OpenGEX format Eric Lengyel's Terathon Software published in 2013, built on the OpenDDL structured-data syntax to lay out a scene's nodes, geometry, materials, skeletons and keyframed animation with a grammar strict enough that a parser doesn't have to guess at intent.
Use OpenGEX when a scene needs a strictly specified, game-engine-oriented interchange format with predictable exporter behaviour.
Convert OGEX to glTF or FBX when the scene needs to move into an engine or DCC tool without native OpenGEX support, which covers most of them.
The OGEX file format reference covers the specification, the programs that open one, and what each conversion keeps or drops.
OGEX questions people ask#
What is an OGEX file?
An OGEX file is a scene in the OpenGEX format, a text-based interchange format built specifically for game engines, storing nodes, geometry, materials, skeletons and animation with a strict, well-defined grammar. Eric Lengyel of Terathon Software published it in 2013.
Why was OpenGEX created?
OpenGEX was created as a more reliably interoperable alternative to COLLADA, whose loose specification let different exporters interpret the same schema in incompatible ways. OpenGEX's stricter grammar was meant to leave less room for that kind of divergence.
What software supports OGEX files?
Terathon's own C4 Engine is OpenGEX's native target, and official export plugins exist for 3ds Max and Maya. Support outside that toolchain is limited, and glTF has become the more widely adopted choice for the same kind of game-engine interchange.
