Used with
3D printing slicers (Cura, PrusaSlicer, Bambu Studio), CAD tools, rapid prototyping workflows.
Wavefront OBJ

Used with
Blender, Maya, Cinema 4D, 3ds Max, ZBrush, and virtually any 3D application.
When to Convert STL to OBJ
Convert STL to OBJ for maximum compatibility with 3D software. OBJ is supported by virtually every 3D application including Blender, Maya, Cinema 4D, and ZBrush. It is a simple text format that stores geometry and basic material references.
