Free Online 3D Model Format Converter in 2026
The 3D world is fragmented by formats — STL for 3D printing, OBJ as the legacy universal format, GLB for the web, USDZ for Apple's AR ecosystem, and FBX for games and film. Different workflows and platforms demand different formats, making format conversion one of the most common needs for 3D professionals.
MeTool's online 3D model format converter accepts STL, OBJ, GLB, GLTF, PLY, FBX, and DAE (Collada) as input, and can export to GLB, USDZ, STL, OBJ, and PLY. The entire conversion process happens locally in your browser — your design files are never uploaded to any server, ensuring intellectual property protection.
In 2026, cross-platform 3D content publishing is the norm. Whether you're converting FBX animation assets to web-ready GLB, or turning OBJ models into printable STL files, MeTool handles it quickly and securely.
Which 3D Format Conversions Are Supported?
Input Formats
MeTool accepts the following input formats: STL (3D printing standard), OBJ (universal mesh format), GLB/GLTF (web 3D standard), PLY (point clouds and scan data), FBX (Autodesk animation format), and DAE (Collada open format).
Output Formats
Export to GLB (recommended for web and game engines), USDZ (Apple AR ecosystem), STL (3D printing), OBJ (universal interchange), and PLY (research and scanning).
