What is an STL File? (STereoLithography Format Explained)
The STL file format (short for STereoLithography) was developed by 3D Systems, a pioneer in the 3D printing industry, to simplify rapid prototyping and manufacturing processes. Today, STL files are one of the most common file types used in computer-aided design (CAD), digital fabrication, and additive manufacturing workflows. STL models exclusively represent 3D geometry as a triangular mesh, offering high compatibility and fast processing across various 3D printers and modeling software.
Key Features of the STL Format
- Lightweight and Simple: An STL file contains only the coordinates of vertices and normal vectors of triangles, making it extremely easy for 3D software and printers to interpret.
- No Textures or Materials: STL models do not store color, texture, transparency, or material information, resulting in pure geometric representations without extra attributes.
- Two Storage Methods: STL files are available in two distinct formats:
- Binary STL: The most popular choice due to its small file size, ideal for faster saving, sharing, and printing.
- ASCII STL: A human-readable text format that explicitly describes each triangle but produces significantly larger files.
- No Fixed Units: The STL format does not define units (millimeters, inches, etc.). Most programs assume millimeters by default. Our STL Files Converter can automatically handle unit adjustments during file conversion if needed.

GLTF and GLB 3D File Format
The GLTF (GL Transmission Format) and GLB file types are modern open standards developed by the Khronos Group for efficient storage, transmission, and rendering of 3D models. Designed for the web, gaming, VR/AR, and real-time applications, these formats enable compact, high-performance 3D asset workflows across platforms.
Key Features of GLTF and GLB Files
- GLTF Versions:
- GLTF 1.0: Supports basic geometry, textures, simple materials, and skeletal animations with joint hierarchies.
- GLTF 2.0: Adds advanced features like PBR (Physically Based Rendering) materials, Draco compression, morph targets, skinning, and enhanced animation capabilities.
- ASCII vs Binary: GLTF files are human-readable (JSON format), while GLB files combine 3D data, textures, and materials into a compact, binary format for faster loading and easier distribution.
- Embedded Textures: Both GLTF and GLB can embed textures directly, creating self-contained 3D assets ideal for web and mobile applications.
Convert GLTF and GLB Files
With Autoconverter and Automesher Application, you can easily import, export, and convert GLTF and GLB files to formats like OBJ, FBX, STL, and more. Our software supports Draco compression, enabling significantly smaller file sizes while preserving the quality and performance of your 3D assets.
