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

About Converting OFF to GLB
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. When you need to move away from OFF, the usual reason is simple: no colour, texture or material data.
Converting your OFF 3D model to GLB solves that. 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. In practice you gain single self-contained file with textures and materials and designed for web, ar and real-time engines. PrivConvert runs the whole OFF-to-GLB conversion in server memory and deletes your file the instant the GLB is ready — nothing is stored, logged or reused.
When this conversion helps
- You need single self-contained file with textures and materials
- You need designed for web, AR and real-time engines
- You need compact and fast to load
- Sharing a OFF 3D model with someone whose software expects GLB
Tips for best results
- Files up to 250 MB are supported, and you can batch-convert several OFF files at once; each is processed privately and deleted immediately.
How to Convert OFF to GLB Online
Turning a OFF file into GLB is straightforward here — upload, convert, download. What you gain with GLB: single self-contained file with textures and materials.
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 OFF to GLB 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 choose PrivConvert?
Converting OFF to GLB should not mean handing a stranger a permanent copy of your data. PrivConvert processes everything in memory and forgets it instantly.
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.
Files are processed in volatile memory (RAM) and purged the instant your download is ready — nothing is ever written to disk, cached or backed up.
Every upload and download is protected with TLS 1.3, so your 3D model cannot be intercepted on the way to the server or back to you.
