Some metadata may not survive
Your GLTF 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，GLTF与OBJ是两种常见的格式，各有千秋。GLTF（GL Transmission Format）作为一种为高效传输和加载而生的现代格式，特别适合在网页和移动应用中展示，它能将模型、材质、动画等信息打包在一起，非常便捷。而OBJ（Object File）则是一种历史悠久、兼容性极强的通用格式，它以其简洁的结构被广泛支持，尤其在模型编辑和不同软件间交换时表现出色。当您需要将一个为网络优化或实时渲染设计的GLTF模型，转换为更便于传统三维软件编辑、雕刻或进行复杂渲染的OBJ格式时，我们的工具就能派上用场。无论您是专业的设计师、游戏开发者，还是三维爱好者，我们都能帮助您轻松完成转换，让您的三维资产在不同平台间自由流转，发挥最大价值。
- 微信小程序3D展示模型导入传统建模软件精修
- 手游角色模型转换为影视动画渲染素材
- 在线展厅模型下载至本地进行二次创作
考虑到中国大陆、台湾及新加坡地区用户常使用微信生态进行内容分享，GLTF在移动端展示上有优势。但若需导入3ds Max, Maya等主流桌面建模软件进行深度编辑，转换为OBJ能提供更顺畅的工作流，避免兼容性问题。
About GLTF to OBJ Conversion
Short answer: yes, you can convert GLTF to OBJ online for free, and quality is well preserved with the right settings. Just upload your .gltf file to CocoConvert, pick OBJ as the output, and click Convert. The whole process takes seconds.
Now for the details. glTF is an open 3D scene format designed for efficient web and real-time delivery. OBJ is a simple 3D geometry format supporting vertices, faces, and texture coordinates. Converting between these two formats lets you convert between formats quickly.
Full Name: GLTF uses GL Transmission Format, while OBJ uses Wavefront OBJ. Compression: GLTF uses Lossless, while OBJ uses None (uncompressed). Typical File Size: GLTF uses 100 KB–50 MB (JSON + separate binary), while OBJ uses 1–500 MB (text-based, large for complex models).
Your GLTF file is decoded and re-encoded as OBJ. Converting GLTF to OBJ maintains high quality with CocoConvert's optimised encoder settings.
CocoConvert runs entirely online — no software to install, no account to create. Your files are encrypted during upload (TLS), processed on isolated servers in Germany, and permanently deleted after 24 hours. It works in Chrome, Safari, Firefox, Edge, and all mobile browsers.
Need to convert more than one file? Free users can do 5 per hour. Pro gets 100 per hour with files up to 5 GB each.

Frequently Asked Questions
Is GLTF to OBJ conversion free?
Yes. CocoConvert offers free GLTF to OBJ conversion with generous daily limits — 25 minutes of processing time and up to 5 files per hour (250 MB each). Pro plans remove these limits.
How fast is GLTF to OBJ conversion?
Most files convert in 2–10 seconds depending on size. Large 3d model files may take 30 seconds. Batch jobs process in parallel for maximum speed.
What happens to my files after conversion?
Your uploaded GLTF file and the converted OBJ file are both automatically deleted from our servers within 24 hours. They are never shared, sold, or analysed.
Does converting GLTF to OBJ lose quality?
Converting GLTF to OBJ maintains high quality with CocoConvert's optimised encoder settings.
Can I convert OBJ back to GLTF?
Yes, CocoConvert supports OBJ to GLTF conversion as well. However, if the original conversion involved lossy compression, converting back won't recover the lost data.
