What is a OBJ file?
OBJ is a widely used 3D model format developed by Wavefront Technologies. It stores geometry data such as vertex positions, UV coordinates, normals, and polygonal faces in a plain-text format.
OBJ is supported by virtually every 3D software application and is commonly used for exchanging models between different programs. It may be accompanied by an MTL file containing material definitions.
How to open OBJ files
OBJ files can be opened in nearly any 3D modeling software, including Blender, Maya, 3ds Max, and SketchUp. They are ideal for model exchange across different platforms.
Use AnyConv to convert OBJ files to STL, FBX, or GLTF for compatibility with specific tools or 3D printers.

What is a STL file?
STL (Stereolithography) is one of the most common 3D file formats used for 3D printing. It describes the surface geometry of a 3D object without including color, texture, or other attributes.
STL files are supported by virtually all 3D printers and modeling software. They are lightweight and easy to process, making them the go-to choice for rapid prototyping and additive manufacturing.
How to open STL files
STL files can be opened in most 3D modeling and slicing programs such as Blender, Cura, TinkerCAD, and Fusion 360. They are essential for 3D printing workflows.
Use AnyConv to convert STL files to formats like OBJ or STEP for further editing or integration with CAD systems.
