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

Destroyed

  • A recorded unit: GLB stores none

Why people convert PLY to GLB

Putting a scan on the web with its colour, which is the natural home for photogrammetry output.

glTF supports per-vertex colour directly, so this is one of the few conversions where PLY's colour survives without being flattened into a single material. A scanned object keeps its surface variation and looks like itself in a browser viewer.

The scale changes. PLY carries no unit, so the numbers are read as millimetres and divided by 1000 into glTF's metres. Scan data usually is millimetres and the result usually lands correctly, but nothing in the source file confirms it, so glance at the reported dimensions before publishing.

What you get

You get a binary GLB file containing the same triangles the PLY 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 conversion runs in your browser. Your file stays on your computer and is not uploaded.

What to check afterwards

  • PLY carries no unit. The numbers in the file are just numbers, so the conversion assumes millimetres. 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.
  • The numbers change. GLB is read in metres and PLY in millimetres, so every coordinate is rescaled. The result is the same physical size, but the numbers in the file are different numbers.
  • 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 PLY carries, so the main reason to choose a different target is what the receiving software accepts.

Going the other way

Convert GLB back to PLY. The reverse conversion also works with mesh geometry. It does not reconstruct exact CAD surfaces. Material data and part structure lost in either direction cannot be restored by converting back. Keep the original file for later edits.

How we know this conversion works

This pair was checked against 4 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.
