Convert OBJ to WRL (Free)

Drop a .obj file, click Export, download the .wrl. The format color 3-D printing bureaus and older analysis tools still ask for.

Also converts STL, GLB, PLY, USDZ, 3MF, STEP from the same file.

Runs in your browser. No upload, no signup, nothing to install.

Also from Innerscene: Circadian Lab, a free lighting calculator for room illuminance, melanopic EML, and glare.

Your OBJ file is read and converted on your own machine. It is never uploaded.

How to convert OBJ to WRL

1
Open your .obj file
Drag it onto the viewer above, or click "Open an OBJ File". Files up to 200 MB open directly; the parse runs in a worker so the page stays responsive.
2
Pick VRML97 in the Export menu
Click Export in the toolbar, then WRL (.wrl).
3
Download
The .wrl is written in the browser and saved straight to your downloads folder. No queue, no email, no watermark.

What survives the conversion

A file conversion is a translation, and formats do not carry the same things. Here is exactly what moves from OBJ into WRL, and what does not.

Geometry	Kept	Both formats store triangle meshes, so the shape transfers directly.
Colors and materials	Reduced	OBJ can hold material colors and WRL holds per-vertex color, so materials are flattened to that.
Textures	Dropped	WRL does not carry texture images, so a textured model arrives in flat material colors.
Layers and structure	Reduced	WRL has named objects but no layers, so each layer becomes a named part instead.
Units and scale	Kept	WRL stores an explicit unit. OBJ does not, so the size is taken from how the viewer read the file. Check the scale once on import.

What the WRL writer emits: VRML97 with an IndexedFaceSet per mesh, IndexedLineSet for linework and PointSet for clouds, classic Material nodes, and per-vertex color where the scene has it. Meters, Y-up, written verbatim.

The source: Wavefront OBJ (.obj)

Triangle and quad geometry, UVs and normals, with material colors from the companion .mtl file.

The target: VRML97 (.wrl)

The format color 3-D printing bureaus and older analysis tools still ask for.

Opens in: Shapeways and other color print bureaus, MeshLab, Blender, legacy simulation tools.

Your file never leaves your computer

Both the OBJ parser and the WRL writer are JavaScript and WebAssembly running in your own browser tab. There is no upload step, no server-side conversion queue, and no copy of your file anywhere but your machine. That matters for drawings under NDA, for client work, and for anything you would not email to a stranger.

Frequently asked questions

▶Is this OBJ to WRL converter free?

Yes. No signup, no watermark, no per-file limit and no paid tier. Innerscene.

▶Is my OBJ file uploaded anywhere?

No. The file is read with the browser file API and converted in the same tab. Nothing is sent to a server unless you explicitly click Share, which is a separate, opt-in feature.

▶Will my colors and materials survive the WRL export?

OBJ can hold material colors and WRL holds per-vertex color, so materials are flattened to that.

▶Do layers and named parts carry into the WRL file?

WRL has named objects but no layers, so each layer becomes a named part instead.

▶Will the WRL open at the right size?

WRL stores an explicit unit. OBJ does not, so the size is taken from how the viewer read the file. Check the scale once on import.

▶How large an OBJ file can I convert?

Up to 200 MB, and the ceiling adapts to how much memory your device reports. The conversion runs on your own hardware, so a desktop with plenty of RAM will handle more than a phone.

▶Can I convert WRL back to OBJ?

Yes, the other direction works too. Bear in mind that anything the first conversion dropped is not restored by converting back. WRL → OBJ

▶Which browsers does it work in?

Chrome, Edge, Firefox and Safari, on Windows, macOS, Linux, iOS and Android. No plugin and no extension.
