I made a cool online tool using _Castle Game Engine_:

[Convert your 3D models to X3D!](https://castle-engine.io/convert.php)

It allows to

- Convert from [any format supported by Castle Game Engine](https://castle-engine.io/creating_data_model_formats.php) (glTF, X3D, VRML, Wavefront OBJ, STL, Collada, 3DS, MD3, Spine JSON…).
- … into [X3D](https://castle-engine.io/vrml_x3d.php), in XML or Classic (VRML) encoding.

Underneath, it uses [tovrmlx3d (command-line application distributed  
together with view3dscene)](https://castle-engine.io/view3dscene.php#section_converting).

It’s free to use for everyone. It’s of course open-source, both the [tovrmlx3d and view3dscene](https://castle-engine.io/view3dscene.php#section_converting), and a set of scripts ([PHP, Docker and shell scripts](https://github.com/castle-engine/cge-www/tree/master/convert-to-x3d)) to make it work as an online tool in a secure and reliable way.

More information on the [tool page](https://castle-engine.io/convert.php). Give it a shot, test your models on it! 🙂
