GLB to PLY Converter
Processing entirely on your device — large files may take a moment.
GLB is the compact binary form of glTF — "the JPEG of 3D": one file carrying geometry, materials and textures, made for the web, AR and game engines. Scanner exports usually arrive as PLY; converting to STL makes them printable.
Because the whole conversion happens on your device, it is instant, unlimited and genuinely private — no accounts, no watermarks, no files on anyone's server. Multiple files are converted in one go.
How GLB compares to PLY
| GLB | PLY | |
|---|---|---|
| Structure | Scene graph + mesh + animation | Point cloud or mesh |
| Materials | PBR, textures embedded | Vertex colors only |
| Compatibility | Web/AR/game engines native | Scanning/scientific stacks |
| Best for | Web, AR and full 3D scenes | Scans and point clouds |

About the GLB format
GLB is the binary form of glTF 2.0 — the format the Khronos Group designed as “JPEG of 3D”. One self-contained file carries geometry, a full scene hierarchy, PBR materials with textures, skeletal animation and morph targets. It is the native asset format of three.js, Unity, Unreal, Blender and WebXR.
Converting to GLB is usually the upgrade path from OBJ/STL: materials become physically based and embedded, and scenes become portable in a single file. One honest caveat: Draco-compressed GLBs save space but many loaders need explicit decoder setup — plain GLB plays everywhere unconditionally.
+ Strengths
- ✓PBR materials, hierarchy and animation in one file
- ✓The web/AR standard — loads natively in three.js
- ✓Compact binary with texture embedding
! Limitations
- −Mesh-only: no CAD solids or NURBS
- −Older niche tools may not know glTF
About the PLY format
PLY (Stanford Polygon File Format) grew out of the Stanford scanning projects of the 1990s and became the standard output of 3D scanners and photogrammetry. Its superpower is custom vertex properties: beyond x/y/z and faces, a PLY can attach color, normals, confidence and scanner-specific channels to every point — which is why point clouds live in it.
It handles meshes too (binary or ASCII), but rendering ecosystems care little for it — no PBR materials, no hierarchy, no animation. Typical workflow: scan or photogrammetry outputs PLY, you clean it, then convert to GLB/OBJ for visualization or STL for printing.
+ Strengths
- ✓Standard of scanning and photogrammetry
- ✓Custom per-vertex attributes (color, normals, confidence)
- ✓Handles dense point clouds efficiently
! Limitations
- −No materials, hierarchy or animation
- −Sparse support in viewers and engines
Why convert GLB to PLY?
There is a concrete reason this conversion exists: Mesh-only: no CAD solids or NURBS PLY sidesteps that — Standard of scanning and photogrammetry If that is your situation, the tool above settles it in seconds, entirely on your device.
Frequently asked questions
Is this GLB to PLY converter really free?
Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.
Are my files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.
Does it work on Windows, Mac, iPhone and Android?
Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.
Will my model look the same as a GLB?
Geometry, hierarchy and standard materials convert faithfully. Note that Draco-compressed GLB files and exotic extensions are not supported — export those as plain GLB from your original tool first.
Will my PLY model keep its colors and textures?
Only if PLY can store them. Geometry converts faithfully; appearance data survives only when the target format has a place to put it. For full materials, GLB is usually the right target.
How large can the GLB file be?
Everything runs on your device, so memory is the only ceiling. Dense meshes with millions of triangles convert fine on a desktop computer, just over a slightly longer coffee break.
