FBX Won't Open? Convert to OBJ Instantly
Fast, instant FBX to OBJ conversion. No signup required. Just drop your .fbx file and get .obj in seconds.
Batch Settings
Some metadata may not survive
Your FBX file may contain FBX properties metadata. OBJ has limited or no support for these metadata types. Location data (GPS), camera settings, and color profiles may be stripped during conversion.
做3D项目的人都知道，FBX是动画和骨骼绑定的主力格式，但一旦要跨软件交付或上传到平台，OBJ的兼容性往往更省心。无论是把角色模型交给甲方审核，还是把场景资产导进不同的渲染器，格式不对就是白费功夫。这个工具帮你直接在浏览器里完成转换，不用装软件，不用折腾插件，上传文件、下载结果，整个过程就这么简单。模型的几何结构和UV信息会完整保留，材质贴图路径也会一并导出，方便后续对接。
- Unity/UE项目资产整理后导出给外包团队审阅
- 淘宝、京东3D商品展示模型的格式标准化
- 影视级角色模型转交给Blender用户二次加工
国内不少游戏公司和影视后期团队仍在用Maya 2018至2022版本，这些版本对FBX的某些新特性支持有限，转成OBJ反而能避免版本兼容问题，在跨团队协作时更稳定。

Frequently Asked Questions
Why won't my FBX file open?
FBX files may not open if your device lacks the right codec or application. Converting to OBJ — a more widely supported format — usually resolves this. OBJ is a simple 3D geometry format supporting vertices, faces, and texture coordinates.
Is it safe to convert FBX to OBJ online?
Yes. CocoConvert encrypts your file via TLS, processes it on isolated servers in Germany, and permanently deletes it within 24 hours. Your files are never shared or analysed.
Will I lose quality converting FBX to OBJ?
Converting FBX to OBJ maintains high quality with CocoConvert's optimised encoder settings. CocoConvert uses high-quality encoder defaults to preserve as much fidelity as possible.
