7 Best Free Online STL to OBJ Converter Websites

Here is a list of the best free online STL to OBJ converter websites. STL is short for Standard Triangle Language or Standard Tessellation Language. It stands for STereoLithography, a native file format of CAD software commonly used in 3D printing. On the other hand, OBJ stands for Object File Format. This format is widely supported in various 3D design and modeling software. Converting STL files to OBJ can allow for better compatibility for 3D modeling and printing.

This post covers 7 free websites where you can convert STL to OBJ online. Each website either offers an STL to OBJ converter or lets you configure a converter for the same. All you have to do is upload your STL file and perform the conversion. Once done, you can save the converted OBJ files. I briefly covered each converter with conversion steps. I also highlighted their features and limitations. You can go through the post to explore those in detail.
