GLB to OFF Converter
Convert a GLB 3D model to OFF online. A self-contained gltf binary built for browsers, ar and game engines becomes a minimal academic mesh format holding little more than vertices and faces.

About Converting GLB to OFF
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 OFF solves that. OFF (Object File Format) is a simple, plain-text mesh format that lists a model’s vertices and faces. It is widely used in academia, geometry-processing research and tools such as MeshLab and CGAL, where a minimal, easy-to-parse mesh format is preferred. In practice you gain human-readable plain text and trivial to parse and generate. PrivConvert runs the whole GLB-to-OFF conversion in server memory and deletes your file the instant the OFF is ready — nothing is stored, logged or reused.
When this conversion helps
- You need human-readable plain text
- You need trivial to parse and generate
- You need standard in research and geometry-processing tools
- Sharing a GLB 3D model with someone whose software expects OFF
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 OFF Online
Turning a GLB file into OFF is straightforward here — upload, convert, download. What you gain with OFF: human-readable plain text.
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 OFF 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.
Why convert GLB to OFF with PrivConvert?
PrivConvert turns your GLB into OFF without ever storing, logging or sharing it. Here is what that looks like in practice:
Convert instantly with no sign-up, no email and no profiling cookies. We never build a profile around you or the files you convert.
Runs in any modern browser on Windows, macOS, Linux, Android and iOS — no install, plugin or desktop software needed.
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 OFF is delivered, both the original and the result are gone — there is nothing left to leak or misuse.
