What Is a X3D File?
X3D is the XML-based successor to VRML, ratified by ISO and maintained by the Web3D Consortium. It keeps VRML’s scene-graph model but switches to XML so it can be processed by standard web and enterprise toolchains.
X3D is the format of choice for technical, scientific, and archival 3D — museums, NIH biomedical datasets, NASA visualizations, and academic research routinely publish X3D. For consumer web 3D (games, AR, e-commerce), modern pipelines use GLB / glTF instead.
Who Uses X3D Files?
Web3D Consortium members, museums and cultural-heritage archives, biomedical / NIH researchers (3D Slicer exports), scientific visualization tools, and CAD packages that prefer an XML interchange.
Common Use Cases
- Preview an X3D scene from a scientific or biomedical dataset
- View a museum / cultural heritage 3D archive entry
- Verify an export from 3D Slicer, Blender X3D exporter, or CAD
- Convert X3D to GLB for modern web and AR delivery
- Convert X3D to OBJ or STL for downstream tools
Features
Open Instantly
Drag and drop an .x3d file — the XML scene graph is parsed in your browser.
Scientific Visualization
Designed for X3D exports from biomedical imaging (3D Slicer), NASA / NIH datasets, and museum archives.
Materials + Primitives
Material colors, primitives, and Transform hierarchies all render in three.js.
3D Navigation
Orbit, pan, and zoom with mouse or touch to inspect the model from every angle.
Convert to GLB
Export X3D as GLB — useful for delivering scientific content to AR / VR viewers.
Convert to OBJ
Save as Wavefront OBJ for use in Blender, MeshLab, or modeling tools.
Convert to STL
Export as STL for 3D printing a scientific or anatomical model.
Export as PDF
Generate a snapshot PDF for research papers, archive notes, or grant reports.
No Upload Required
Your .x3d is parsed entirely in your browser. Nothing leaves your device.
Embed on Any Site
Add the X3D viewer to your website with a single iframe embed code.
Compatibility & Format Notes
X3D 3.x scenes parse via three.js’s VRML/X3D loader. Geometry, primitives, materials, and Transform hierarchies load. Sensors, scripts, and routing (the interactive / behavioral layer) are not interpreted — the static scene renders.
Embed on Your Website
Add this viewer to your own site with a single line of HTML. Click Embed in the toolbar to generate an embed code, or use the snippet below with your own file URL.
Your Files Stay on Your Computer
Your X3D files are parsed entirely in your browser. Nothing is uploaded, stored, or shared unless you explicitly click the Share button. Shared files are hosted for 90 days then deleted.
Frequently Asked Questions
▶What is the difference between X3D and VRML?
X3D is the XML version of VRML. Same scene-graph model, modern syntax that’s easier for tools to process. X3D supersedes VRML for new work but VRML files (.wrl) are still common.
▶Should I use X3D or glTF?
For consumer web 3D, AR, games, or e-commerce: use GLB. For scientific / technical / archival visualization where metadata, declarative scene structure, and long-term stability matter: X3D is the right pick.
▶Can I convert X3D to GLB?
Yes — click Export → glTF Binary. Useful for delivering scientific 3D content to modern web and AR viewers.
▶Is this X3D viewer really free?
Yes, completely free. No signup, no watermarks, no file size limits on the viewer (the optional share-link feature has a 30 MB upload cap). Built by Innerscene as a tool for architects, engineers, and designers.
▶Are my files uploaded to a server?
No. All parsing, rendering, and conversion runs in your browser — nothing is uploaded, stored, or transmitted by default. The Share button is the only feature that uploads a file, and only when you explicitly click it.
▶Can I convert to another format?
Yes. Click Export in the toolbar to save as STL (3D printing), OBJ (Wavefront), GLB (glTF binary), or PDF (snapshot of the current view).
▶Can I embed this viewer on my own site?
Yes. Click Embed in the toolbar to generate a one-line <iframe> snippet you can paste into any HTML page. You can choose whether the embed shows the viewer’s toolbar.
