GLB to PLY Converter
Convert a GLB 3D model to PLY online. A self-contained gltf binary built for browsers, ar and game engines becomes a scanning and research format that can store per-vertex colour and custom properties.

About Converting GLB to PLY
GLB is the binary form of glTF, the "JPEG of 3D" — a modern, compact format that packs geometry, materials, textures and scene data into one self-contained file. It is the standard for the web, AR/VR and real-time 3D viewers. When you need to move away from GLB, the usual reason is simple: not a 3d-printing format.
Converting your GLB 3D model to PLY solves that. PLY (the Stanford Triangle Format) stores a polygon mesh and can carry per-vertex colour, normals and custom properties. It is the standard output of 3D scanners and photogrammetry pipelines, available in both ASCII and binary variants. In practice you gain per-vertex colour and custom attributes and standard for 3d scans and photogrammetry. PrivConvert runs the whole GLB-to-PLY conversion in server memory and deletes your file the instant the PLY is ready — nothing is stored, logged or reused.
When this conversion helps
- You need per-vertex colour and custom attributes
- You need standard for 3D scans and photogrammetry
- You need aSCII and compact binary variants
- Sharing a GLB 3D model with someone whose software expects PLY
Tips for best results
- Files up to 250 MB are supported, and you can batch-convert several GLB files at once; each is processed privately and deleted immediately.
How to Convert GLB to PLY Online
You can convert GLB to PLY right in your browser in under a minute. What you gain with PLY: per-vertex colour and custom attributes.
Drag and drop your file into the upload area, click to browse your device, or paste a URL to a file hosted online. You can upload files up to 250 MB and batch convert up to 20 files at once.
Once uploaded, the conversion from GLB to PLY starts automatically. The process runs entirely in an isolated environment - your data never leaves the secure pipeline.
Your converted file is ready instantly. Click the download button to save it to your device. The file is deleted from memory immediately after download.
Private by design, not as an afterthought
Most online converters upload your files to a server, keep them for days, and may mine them for AI training or resale. PrivConvert was built the opposite way — around your privacy.
Each job runs in an isolated in-memory sandbox, so most conversions finish in seconds instead of waiting in a queue.
We never keep a copy. Once your PLY is delivered, both the original and the result are gone — there is nothing left to leak or misuse.
Every conversion runs in its own locked-down process with no network access, so files can never leak or interfere with one another.
Your files are handled entirely by automated code. No staff, partner or AI model ever reads, stores or trains on your data.
