GLB to OBJ for 3D Model Workflows
Fast, instant GLB to OBJ conversion. No signup required. Just drop your .glb file and get .obj in seconds.
Batch Settings
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.
在三维模型的世界里，GLB和OBJ是两种非常常见的格式，各自有其擅长的领域。GLB以其一体化的封装特性，在网页展示、AR应用和移动端分享上展现出独特的优势，尤其适合在微信等社交平台快速预览。然而，当您需要对模型进行更深度的编辑、拆分材质，或是在一些传统的专业三维软件中进行精细化操作时，OBJ格式的开放性和广泛兼容性便显得不可或缺。它将几何数据与材质贴图分离存储，为后续的二次创作和跨平台协作提供了极大的便利。无论您是游戏开发者、设计师，还是仅仅想将心仪的模型导入不同工具，了解并掌握这两种格式的转换，都将为您的三维工作流带来质的飞跃。我们的工具旨在提供一个简单、高效的转换方案，助您轻松驾驭这两种主流格式。
- 游戏角色模型导入旧版引擎
- 3D打印模型精修前处理
- AR模型转为传统CG渲染
在大陆及台湾地区，许多老牌三维软件和工业设计流程仍偏好OBJ的开放性。此外，将GLB转换为OBJ，有助于解决部分国产三维软件对GLB支持不完善的问题，尤其在材质和贴图处理上，OBJ能提供更稳定的兼容性。
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.
