Free GLB to PLY converter

Why convert GLB to PLY?

People convert GLB to PLY because a GLB packs an entire scene into one binary file that cannot be opened and edited as text, while PLY carries per-vertex colour, which suits scanned and point-cloud data.

How to convert GLB to PLY

1. Choose your GLB file. Drop it on the box above, or tap to browse. You can pick several files at once.
2. Confirm the target is .ply. It is preselected when your browser can encode it; otherwise the closest available target is chosen. Adjust quality, size or the other options if you want to.
3. Convert and download. Press Convert, then Download. Your file stays on your device the whole time.

What is a .glb file?

GLB is the single-file binary form of glTF, and the format the augmented-reality world has standardised on — Android's Scene Viewer, web viewers, Unity and three.js all take one directly. Geometry, materials and animation travel in one file that loads fast.

What is a .ply file?

PLY was designed at Stanford for scanned 3D data and remains the common format for point clouds and photogrammetry output. It can carry per-vertex colour and arbitrary custom properties, which is why research tooling favours it.

What to expect from this conversion

Geometry is converted exactly, with node transforms applied so the model keeps its pose. Materials, textures and animation are not carried across. Check the scale in your viewer: STL files carry no units, so a model exported in millimetres can appear a thousand times too large.

Is it private?

Yes, by design. Every conversion happens inside your own browser using your device’s processor — there is no server that receives your GLB file, so there is nothing for anyone to store, scan or leak. You can confirm it yourself: open your browser’s developer tools, watch the Network tab while you convert, and you will see no upload.

Questions about GLB to PLY

Is this GLB to PLY converter free?

Yes, completely. There is no account, no daily limit, no watermark and no premium tier.

Is my GLB file uploaded to a server?

No. The conversion runs inside your own browser using your device's processor. The file is read from your disk, converted in memory and saved back to your disk — nothing is transmitted, so there is nothing for anyone to store.

Can I convert GLB to PLY online without downloading software?

Yes. This is an online GLB to PLY converter that runs in your browser, so there is nothing to install and no app to trust with your files. It works the same on a phone.

What happens to the quality?

Geometry is converted exactly, with node transforms applied so the model keeps its pose. Materials, textures and animation are not carried across. Check the scale in your viewer: STL files carry no units, so a model exported in millimetres can appear a thousand times too large.

Can I convert several GLB files at once?

Yes. Select as many files as you like and they are converted one after another in a single tap, with a download for each and a zip of all of them.

Can I convert GLB to PLY without Blender or a script?

Yes — that is what this page is for. Blender does the same job well if you already have it set up and thousands of files to process; for one file, or a handful, the browser is faster than installing anything.

Should I keep the original GLB file?

Yes — keep it, converting never touches it. The reason to make a copy in another format is that a GLB packs an entire scene into one binary file that cannot be opened and edited as text.
