免费 3D 格式转换器
在浏览器本地转换 GLB、OBJ、STL 等常见模型格式,适合 3D 交付流程。
先在本地转换常见 3D 模型格式,不上传文件。
关于这个工具:免费 3D 格式转换器
Convert GLB, OBJ, and STL model files locally in the browser for common 3D handoff workflows. 无需上传——全部处理都在你的浏览器本地完成,兼顾隐私与速度。
常见用法
- 转换在浏览器本地运行,不需要上传模型。
- STL 输出只保留几何,这是格式本身的限制。
- 生产交付前,建议在目标 DCC、引擎或切片软件里再打开确认。
在 3D 格式之间转换
每种 3D 格式都是一次取舍:GLB 保外观,STL 只保几何,OBJ 保兼容。先确定去向,再从你手里信息最全的文件往下转,让损失只发生一次、发生在最后。
怎么转才不叠加损失
- 1
先定去向,再选格式
打印就是 STL,老编辑器就是 OBJ,网页或引擎就是 GLB。是去向决定格式,不是反过来。
- 2
永远从母版转
从原始 GLB 转。STL 转 OBJ 再转 GLB 会把损失叠两次,而第一次丢掉的永远回不来。
- 3
转完验一遍
用查看器打开结果,确认面数和包围盒都还在。
3D 转换常见问题
- 这里能做哪些转换?
- GLB 转 OBJ、GLB 转 STL、OBJ 转 GLB、STL 转 OBJ —— 3D 交接真正需要的四组。
- 转换要花钱吗?
- 不用。转换在浏览器本地运行,不消耗任何积分,也不需要账号。
- 转换能把丢失的贴图找回来吗?
- 不能。只有原始文件里有;转换可以丢数据,但造不出数据。
小提示
- 转换在浏览器本地运行,不需要上传模型。
- STL 输出只保留几何,这是格式本身的限制。
- 生产交付前,建议在目标 DCC、引擎或切片软件里再打开确认。
