About Converting OFF to OBJ
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 OBJ solves that. OBJ is a widely supported 3D geometry format that stores vertices, faces, texture coordinates and normals as plain text. It is a common interchange format between modelling, rendering and CAD applications, optionally pairing with an .mtl file for materials. In practice you gain human-readable text and supports texture coordinates and normals. PrivConvert runs the whole OFF-to-OBJ conversion in server memory and deletes your file the instant the OBJ is ready — nothing is stored, logged or reused.
When this conversion helps
- You need human-readable text
- You need supports texture coordinates and normals
- You need read by almost every 3D application
- Sharing a OFF 3D model with someone whose software expects OBJ
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 OBJ Online
You can convert OFF to OBJ right in your browser in under a minute. What you gain with OBJ: human-readable 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 OFF to OBJ 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.
A more private way to convert OFF files
Plenty of sites convert OFF files. Very few promise never to keep them — PrivConvert does, and backs it up with how the service is built.
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.
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.
