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 and edited in most 3D modeling and slicing programs such as Blender, Cura, TinkerCAD, or Fusion 360. They represent the geometry of 3D objects using triangles and are essential for prototyping and 3D printing workflows.
Use AnyConv to convert STL files to formats like OBJ or STEP for further editing, or to generate GCODE directly for 3D printing. It’s a fast and convenient way to prepare your models online without installing extra software.

❓ Frequently Asked Questions
- Why should I convert OBJ to STL?OBJ is a popular 3D model format, but many slicers and 3D printers only accept STL. Converting OBJ to STL makes your model ready for slicing and 3D printing.
- Will my 3D model lose detail after conversion?No. The converter keeps the original geometry and scale of your model. Since both OBJ and STL store mesh data, the visual shape remains identical.
- Can I use my converted STL file for 3D printing?Yes. Once you’ve converted your OBJ model to STL, you can generate G-code for your printer using our STL to G-code tool - it prepares the file for actual printing.
- Does the converter include textures or colors from the OBJ file?STL format doesn’t support materials or colors - it only contains geometry. If your OBJ model includes textures, those will not appear in the STL version.
- Can I batch convert multiple OBJ files to STL?Yes. You can upload several OBJ models at once, and our online converter will create separate STL files for each in a single step.
- Is it safe to convert OBJ to STL online?Absolutely. All 3D models are transferred securely, processed only for conversion, and automatically deleted from our servers shortly after.
