Convert VRML to GLB
Convert VRML to GLB in your browser. The conversion runs on this page and the file never leaves your computer.
Result
Before you convert: what this keeps and what it destroys
Preserved
- The geometry, triangle for triangle
- Overall dimensions and proportions
- Watertightness, where the input is watertight
- Colour
- Separate parts and their positions
Destroyed
- A recorded unit: GLB stores none
Why people convert VRML to GLB
The modern replacement, doing the job VRML was invented for. VRML was the 1990s attempt at 3D on the web and glTF is what actually succeeded at it, so this conversion is a thirty-year update in one step.
Colour survives, which is the point. Material colours become glTF base colours, and VRML's nested Transform nodes become a real node hierarchy, so a structured scene stays structured.
Both formats treat the metre as their unit, so in principle nothing is rescaled here. In practice VRML files written by CAD exporters often hold millimetre-magnitude numbers regardless of what the specification says, and if that is your file the GLB will be a thousand times too large. Look at the reported dimensions before you publish it.
What you get
You get a binary GLB file containing the same triangles the VRML file described. No geometry is added, removed or approximated: mesh-to-mesh conversion is a change of container, and this site's tests check that the triangle count comes out identical.
The output uses metres, as required by the glTF specification.
Carried across: supported base or vertex colour, the supported part structure.
The conversion runs in your browser. Your file stays on your computer and is not uploaded.
What to check afterwards
- VRML carries no unit. The numbers in the file are just numbers, so the conversion assumes metres. Check the overall dimensions of the result before you commit to machining or printing it. A file exported from a package set to inches will be 25.4 times out.
- Coordinates are stored as 32-bit floats. For a part measured in millimetres that's far finer than any machine tolerance. For a model spanning hundreds of thousands of units it isn't.
If you need something this conversion cannot give you
This pair loses very little. GLB carries what VRML carries, so the main reason to choose a different target is what the receiving software accepts.
Going the other way
This site reads VRML but does not write it. For the reverse conversion, use an application that can export VRML.
How we know this conversion works
This pair was checked against 2 files from the test corpus on 2026-09-04. Each run parses its own output back in and compares the bounding box, the triangle count and, for closed solids, the volume against the input.
A pair that fails those checks doesn't get a page. That's why this site lists 120 conversions and not the several hundred a format-times-format grid would suggest.
