How to Create an X3D File Online

01
Open the viewer
Head to the home page - it works in any modern desktop or mobile browser.
02
Load your STL model
Drag and drop the file into the viewer, use the Open button, or load it from a URL, then inspect it in 3D.
03
Export as X3D
Use the export button and choose X3D. The web-ready file downloads straight from your browser.

Private

Rendering happens locally with WebGL. Nothing is uploaded to a server.

Instant

No plugins, downloads, or accounts — the viewer runs entirely in your browser.

About the Extensible 3D (X3D) Format

X3D (Extensible 3D) is the ISO-standard, XML-based format for representing interactive 3D scenes, developed by the Web3D Consortium as the successor to VRML. Because it is XML, an X3D file is human-readable and can describe not just geometry but complete scenes: materials, lights, viewpoints, and animation.

X3D is used in scientific and medical visualization, CAD data exchange, and web-embedded 3D. Historically it required browser plugins or specialized frameworks to view - a WebGL-based viewer like this one displays X3D geometry with no setup at all.

X3D Viewer FAQ

How is X3D different from VRML?

X3D is the modern successor to VRML (Virtual Reality Modeling Language). It keeps VRML's scene-graph concepts but uses XML encoding, adds new components, and is maintained as an ISO standard by the Web3D Consortium.

Do I need a plugin to view X3D files?

Not anymore. Older X3D workflows relied on browser plugins, but modern web frameworks like X3DOM render X3D with WebGL, which is built into every browser. Desktop tools like Blender and view3dscene also open X3D files directly.

Can I create an X3D file from an STL model?

Yes. Load an STL file into our viewer, preview it in 3D, and export it as X3D - the conversion runs locally in your browser, so the model is never uploaded.
