X3DV Converter
FileFlip converts X3DV files into 14 other formats entirely inside your browser, using Assimp compiled to WebAssembly. The X3DV 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 X3DV file?#
- Drop your X3DV 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 X3DV files online?#
Yes, because nothing is uploaded. FileFlip converts X3DV 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 X3DV file?#
An X3DV file holds an X3D scene written in ISO's ClassicVRML encoding, the VRML97-style plain-text syntax used in place of X3D's XML form.
Use X3DV when a tool inherited from the VRML era only knows how to emit VRML-style syntax but the scene still needs X3D's features.
Convert X3DV to X3D XML for anything expecting the more widely supported encoding.
The X3DV file format reference covers the specification, the programs that open one, and what each conversion keeps or drops.
X3DV questions people ask#
What is the difference between X3D and X3DV?
X3D and X3DV hold the same kind of scene, but X3D under the .x3d extension is written as XML, while X3DV under .x3dv uses ISO's ClassicVRML text encoding instead, styled after VRML97's original syntax.
Is X3DV the same as VRML?
X3DV looks like VRML97 syntax and is built on it, but it's an X3D encoding, so it carries X3D's full feature set rather than being limited to what VRML97 itself supported.
What opens an X3DV file?
FreeWRL, the open-source VRML and X3D browser, reads X3DV directly on Windows, macOS and Linux.
