How to convert a 3D model in compatibility?

To convert a 3D model for compatibility, use a tool (like Blender or online services) to change its file format to one supported by your target software or hardware. Different tools (e.g., 3D printers, animation software) need specific formats—STL for printing, FBX for animation, glTF for web. Universal formats like OBJ help with basic compatibility. If unsure the target format, check the software’s documentation first; online tools are fast for simple models, while Blender offers more control for complex ones with textures or rigs.
