Convert WRL to AMF (Free)
Also converts STL, OBJ, GLB, PLY, USDZ, 3MF 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.
How to convert WRL to AMF
- 1
Open your .wrl file
Drag it onto the viewer above, or click "Open a WRL File". Files up to 200 MB open directly; the parse runs in a worker so the page stays responsive.
- 2
Pick Additive Manufacturing File Format in the Export menu
Click Export in the toolbar, then AMF (.amf).
- 3
Download
The .amf 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 WRL into AMF, and what does not.
| Geometry | Kept | Both formats store triangle meshes, so the shape transfers directly. |
|---|---|---|
| Colors and materials | Reduced | WRL can hold per-vertex color and AMF holds one color per object, so materials are flattened to that. |
| Textures | Dropped | AMF does not carry texture images, so a textured model arrives in flat material colors. |
| Layers and structure | Dropped | AMF is a single flat body with no layers or named parts. Everything merges into one object. If you need the structure, export to GLB, OBJ, DXF instead. |
| Units and scale | Kept | AMF stores an explicit unit, so the model opens at true size without rescaling. |
| Lines and points | Dropped | AMF geometry is manifold mesh only, like 3MF, so line work and point clouds are skipped. |
What the AMF writer emits: AMF 1.1 XML in millimeters, Z-up, with one <object> per mesh and a <material> per distinct color referenced from its <volume>.
The source: VRML (.wrl, .vrml, .wrz)
VRML 2.0 and VRML 1.0: IndexedFaceSet, IndexedLineSet and PointSet shapes with their materials, including PROTO definitions, Switch and LOD nodes, and gzipped .wrz files.
The target: Additive Manufacturing File Format (.amf)
The XML print format 3MF was built to replace, still read by some slicers and print services.
Opens in: Cura, some slicers and 3-D printing services.
Your file never leaves your computer
Both the WRL parser and the AMF 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.
Free to Use, No Signup
There are no accounts and no watermarks on this converter. If it saved you time, the one thing we ask is a mention: a post, a link from your blog or course page, or a reply to someone asking how to open a file.

Frequently asked questions
▶Is this WRL to AMF converter free?
Yes. No signup, no watermark, no per-file limit and no paid tier. Innerscene.
▶Is my WRL 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 AMF export?
WRL can hold per-vertex color and AMF holds one color per object, so materials are flattened to that.
▶Do layers and named parts carry into the AMF file?
AMF is a single flat body with no layers or named parts. Everything merges into one object. If you need the structure, export to GLB, OBJ, DXF instead.
▶Will the AMF open at the right size?
AMF stores an explicit unit, so the model opens at true size without rescaling.
▶How large a WRL 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 AMF back to WRL?
Not here. We read WRL and write AMF, but not the reverse. the universal 3D viewer
▶Which browsers does it work in?
Chrome, Edge, Firefox and Safari, on Windows, macOS, Linux, iOS and Android. No plugin and no extension.
Convert WRL to something else
Save VRML as an older version
Older software cannot open files saved by newer versions. These save a copy in the version the other side needs.
Convert something else to AMF
Or start from the universal 3D viewer.
