Some metadata may not survive
Your GLB file may contain glTF extras, extensions metadata. OBJ has limited or no support for these metadata types. Location data (GPS), camera settings, and color profiles may be stripped during conversion.
日頃より3Dモデル制作に携わる皆様、あるいはこれから足を踏み入れようとされている皆様、こんにちは。GLBファイルは、その手軽さからウェブ上での共有やAR/VRコンテンツに広く利用されていますが、既存の多くの3DソフトウェアではOBJ形式が依然として標準的な交換フォーマットとして重宝されています。特に、長年培われてきた制作ワークフローを大切にする日本のクリエイターの皆様にとって、使い慣れた環境で細部までこだわり抜いたモデルを編集できることは、作品の質を左右する重要な要素でしょう。このページでは、お手持ちのGLBファイルを、より汎用性の高いOBJ形式へスムーズに変換する方法をご紹介します。複雑な設定は不要で、直感的な操作で高品質な変換が可能です。皆様の創造性を最大限に引き出すお手伝いができれば幸いです。
- ゲーム開発での互換性確保
- 建築ビジュアライゼーションでの利用

日本の多くの3Dアニメーションスタジオでは、長年の制作資産としてOBJ形式が深く根付いており、GLBからの変換は既存パイプラインへの統合において重要な工程となることがあります。
About GLB to OBJ Conversion
Whether you're one of the many professionals working with 3d model files who work with GLB files daily, there comes a time when you need OBJ instead. GLB is the binary version of glTF — the "JPEG of 3D" used in web, AR, and game engines.
Here's a typical scenario: you receive a .glb file but your project, platform, or client requires .obj. OBJ is a simple 3D geometry format supporting vertices, faces, and texture coordinates. Rather than searching for desktop software or wrestling with command-line tools, you can convert GLB to OBJ online in seconds with CocoConvert.
This conversion is ideal when you When you specifically need a OBJ file for your workflow. The conversion helps you convert between formats quickly.
Converting GLB to OBJ maintains high quality with CocoConvert's optimised encoder settings.
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.
