OFF to GLB for 3D Model Workflows
Fast, instant OFF to GLB conversion. No signup required. Just drop your .off file and get .glb in seconds.
Batch Settings
3Dモデルの作成や共有において、OFF形式はその簡潔さから学術分野などで用いられてきました。しかし、ウェブ上でのインタラクティブな表現や、より幅広いアプリケーションでの利用を考えた場合、GLB形式への変換が不可欠となります。GLBは、モデルデータだけでなくテクスチャやアニメーションも単一ファイルにまとめられるため、特に日本のデジタルコンテンツ業界、例えばゲーム開発やバーチャル展示会、あるいはVTuberのアバター制作といった場面で、その利便性が高く評価されています。このページでは、お手持ちのOFFファイルを、現代のデジタル環境に最適化されたGLB形式へとスムーズに変換するお手伝いをいたします。複雑な設定は不要、どなたでも簡単にご利用いただけます。

日本のアニメ・マンガ文化では、3Dモデルの表情や細部のテクスチャ表現が非常に重視されるため、GLB形式の効率的なデータ統合は、クリエイターにとって大きなメリットとなります。
About OFF to GLB Conversion
Whether you're one of the many professionals working with 3d model files who work with OFF files daily, there comes a time when you need GLB instead. OFF (Object File Format) is a simple geometry format for describing 3D polyhedra.
Here's a typical scenario: you receive a .off file but your project, platform, or client requires .glb. GLB is the binary version of glTF — the "JPEG of 3D" used in web, AR, and game engines. Rather than searching for desktop software or wrestling with command-line tools, you can convert OFF to GLB online in seconds with CocoConvert.
This conversion is ideal when you Your OFF file won't open on a recipient's device or in an application, or when you A website, service, or platform only accepts GLB uploads. The conversion helps you improve file compatibility across devices.
Converting OFF to GLB maintains high quality with CocoConvert's optimised encoder settings. Common misconception: ""GLB will be smaller than my OFF file"" — in reality, glb uses lossless compression, so the output file is often larger than a lossy off. if you need a small file, glb may not be the right choice.
Behind the scenes, CocoConvert uses industry-standard tools — FFmpeg for audio and video, Sharp for images, qpdf for documents. Your file is uploaded securely (TLS encryption), processed on isolated servers in Germany, and auto-deleted within 24 hours. No account, no watermark, no hidden fees.
Power users can batch convert up to 100 files simultaneously with a Pro subscription, making it practical for production workflows.
