Why Use Our 3D Model Converter?
Our 3D model converter is the essential tool for 3D artists, game developers, and makers. Whether you need to convert OBJ to STL for 3D printing, transform FBX to GLTF for web deployment, or pack GLTF as GLB for distribution, our online 3D converter handles it all with professional-grade accuracy. Support for all major 3D formats including OBJ, STL, GLTF, GLB, FBX, DAE, and PLY.
Why Convert 3D Model Formats?
3D format conversion is essential across many industries and workflows. With our 3D model converter, you can prepare models for 3D printing by converting to STL, optimize assets for games and web by converting to GLTF/GLB, import CAD designs into 3D software by converting FBX or DAE, share models across different platforms with universal formats, and reduce file sizes while maintaining quality. Our free online 3D converter bridges the gap between different software ecosystems.
3D Formats Explained
OBJ (Wavefront)
One of the oldest and most universal 3D formats. Stores geometry, texture coordinates, and normals. Widely supported but lacks animation and modern PBR materials. Great for static models and interoperability.
STL (Stereolithography)
The standard format for 3D printing. Contains only geometry as triangular meshes. No color, texture, or material data. Convert to STL when preparing models for 3D printers.
GLTF/GLB
The "JPEG of 3D" - modern format designed for efficient web delivery. GLTF is JSON with separate files; GLB is binary all-in-one. Supports PBR materials, animations, and skins. Convert FBX to GLTF for web use.
FBX (Filmbox)
Autodesk's proprietary format widely used in game development and film. Supports geometry, materials, animations, cameras, and lights. Common in Unity, Unreal Engine, and professional 3D software.
DAE (Collada)
XML-based interchange format for 3D applications. Supports geometry, materials, animations, and physics. Open standard but can produce large files. Good for CAD to game engine workflows.
PLY (Polygon File)
Format designed for 3D scanning data. Stores vertex colors and can include point cloud data. Used in photogrammetry and 3D scanning workflows. Convert to OBJ or STL for broader compatibility.

How to Use Our Online 3D Converter
Using our 3D model converter is straightforward. Upload your 3D model file (OBJ, STL, GLTF, FBX, or any supported format), select your desired output format, and click convert. Our online 3D converter processes your model server-side, converting geometry and preserving as much data as the target format supports. Download your converted model and use it in your target application.
Popular 3D Conversion Use Cases
- OBJ to STL:Prepare models for 3D printing and slicing software
- FBX to GLTF:Convert game assets for web and AR/VR deployment
- GLTF to GLB:Package GLTF as single binary for easy distribution
- STL to OBJ:Convert 3D printed models for editing and texturing
- DAE to FBX:Import Collada files into Unity or Unreal Engine
- PLY to OBJ:Convert 3D scan data for standard 3D software
3D Printing Workflow
Whether you're using a FDM, SLA, or SLS printer, our 3D converter helps prepare your models. Most slicing software (Cura, PrusaSlicer, Simplify3D) require STL files. Convert OBJ to STL or any other format to get your models 3D-print ready. Our converter ensures manifold meshes and proper geometry for successful prints.

Frequently Asked Questions
What 3D model formats can I convert?
Our 3D converter supports OBJ, STL, GLTF, GLB, FBX, DAE (Collada), PLY, OFF, and 3DS formats. Convert between any of these formats for 3D printing, game development, AR/VR, or CAD workflows.
Which format is best for 3D printing?
STL (Stereolithography) is the industry standard for 3D printing. Most 3D printers and slicing software accept STL files. Our OBJ to STL converter is perfect for preparing models for 3D printing.
What is the difference between GLTF and GLB?
GLTF is a JSON-based format with separate texture files, while GLB is a binary version that packages everything into a single file. GLB is more convenient for distribution, while GLTF is easier to edit.
Is the 3D model converter free to use?
Yes! Basic 3D model conversion is completely free. Free users can convert files up to 250MB with 10 conversions per day. Premium plans offer larger file sizes up to 10GB and unlimited conversions for complex 3D models.
Will converting preserve textures and materials?
Texture preservation depends on format compatibility. Conversions between GLTF/GLB/FBX preserve textures well. STL and OBJ are geometry-only formats, so texture information may be lost when converting to these formats.
Can I convert FBX files for web use?
Yes! Convert FBX to GLTF or GLB for web-optimized 3D content. GLTF is the standard format for WebGL and Three.js applications, AR/VR experiences, and 3D viewers on the web.
