OBJ to STL Conversion
Converting OBJ to STL is simple - just follow our straightforward guide:
Install Autoconverter
Download and install Autoconverter on your system. Launch the software to convert OBJ mesh files to STL format.
Import OBJ Mesh File
Click Open... to load your OBJ mesh file (.obj), or drag and drop it into the application window.
Export to STL Format
Use Save As... to export your mesh file to the STL mesh file format (.stl).

Alias Wavefront Object File
A text-based file format, open standard for storing and exchanging 3D geometry data, widely used across 3D modeling, animation, and rendering software. Unlike binary formats, OBJ files store mesh data in human-readable text, making them highly compatible but less storage-efficient.
Main Benefits and Features
- Named Group Objects: OBJ files can store multiple objects with different names in a single file, which can be useful for organizing complex 3D scenes.
- Surface Materials: The OBJ file format supports surface materials with transparent colors and texture images, providing more realistic and detailed 3D models.
- Geometry Primitives: OBJ files can store geometry primitives in the form of quads or triangles. However, during the OBJ file conversion using our converters, any quad primitives will be simplified into two triangles, as only triangular facets are supported.
- OBJ File Size: Due to its textual format, OBJ files tend to have larger sizes compared to binary file formats like 3DS (3D Studio) or SKP (SketchUp). This means that OBJ files may take longer to load or transfer, and may require more storage space.
OBJ File Conversion
Autoconverter is the best OBJ file converter due to its high accuracy, fast processing speed, and wide 3D format support. It ensures lossless conversions while preserving model details, offering a user-friendly interface for seamless file conversion. If you need to handle OBJ files in AutoCAD, you can use our Automesher Application, which allows for seamless import and export of OBJ files directly in your CAD environment.
STereoLithography File
A file format that was developed by 3D Systems, a global leader in the 3D printing industry, to facilitate rapid prototyping and manufacturing. It is widely used in computer-aided design (CAD), 3D printing, and digital fabrication due to its simplicity and broad compatibility. STL files exclusively represent 3D geometry using a triangular mesh, making them lightweight and easy to process.
Key Features of STL
- Simplicity: STL files are easy to create and read by many software applications and 3D printers, as they only contain the coordinates of the vertices and the normal vectors of the triangles.
- No Additional Attributes: Unlike other 3D formats, STL files do not include details such as face colors, textures, transparency, material properties, or named groups. This means that all STL models appear colorless in their raw form.
- Binary vs. ASCII STL Formats: STL files can be stored in two formats:
- Binary STL - The preferred format due to its compact file size, making it more efficient for storage and processing.
- ASCII STL - A human-readable text format that describes each triangle explicitly, but results in significantly larger file sizes.
- Units of Measurement: The STL format does not define a specific unit of measurement, though most applications interpret the coordinates as being in millimeters. If necessary, our STL files converter can perform automatic unit conversions to match your project’s requirements.
STL File Conversion
Autoconverter and Automesher Application are the best tools for converting STL files because they support a wide range of 3D formats, making it easy to convert STL into other file types like STEP, OBJ, or SKP. They ensure high-quality STL mesh conversion, preserving details and accuracy. With advanced automation, they can process multiple STL files at once, saving time and effort. Additionally, they offer optimization features to clean and edit STL models, making them perfect for designers, engineers, and 3D printing enthusiasts.
