Free converter

Convert GLB to PLY for analysis.

Drop a .glb below and download the geometry as a binary PLY for MeshLab, CloudCompare, Open3D or any geometry-processing pipeline. Everything runs locally in your browser — nothing is uploaded.

Why this tool

Free, private, in the browser.

Web asset to analysis format

Take an AI-generated or downloaded GLB into the tools built for measuring, decimating and inspecting meshes.

Scene flattened cleanly

Every mesh in the GLB is combined with its transforms applied, so the PLY matches the rendered model.

In-browser, instant, private

Parsed and re-exported with three.js in browser memory — no server round-trip.

How it works

Three steps, no setup.

01
Drop your GLB

Drag the .glb in — it renders a live textured preview.

02
Convert to PLY

The scene's meshes are merged and written as binary PLY, locally.

03
Open in your tool

Load the .ply in MeshLab, CloudCompare or your Open3D / trimesh script.

Why convert GLB to PLY?

GLB is a rendering container; PLY is what the measurement and processing world speaks. Typical reasons to cross over: checking an AI-generated model's mesh quality, decimating a heavy asset, comparing a model against a reference scan in CloudCompare, or feeding geometry into a Python pipeline with Open3D or trimesh. This converter extracts the triangles so those tools can get to work.

What the PLY contains

The merged triangle geometry of every mesh in the scene, with normals, in compact binary PLY. PBR materials and texture images don't transfer — PLY has no material system — but that's irrelevant for the geometric analysis PLY is used for. Keep the GLB as the textured original.

Questions

Answered, plainly.

Is the GLB to PLY converter free?+

Yes — completely free, no signup, no limits.

Is my model uploaded?+

No. The conversion runs client-side; the model never leaves your machine.

Do textures transfer to the PLY?+

No — PLY has no texture or material system. You get the full geometry with normals, which is what analysis tools consume.

My GLB has several parts — what ends up in the PLY?+

All meshes, merged with their scene transforms applied, matching what you saw in the preview.
