Common 3D Conversion Use Cases
Convert OBJ or STL files to GLB/GLTF for web-based 3D viewers and AR experiences. GLB format is optimized for web delivery with smaller file sizes.
Convert GLB, GLTF, or OBJ files to STL format for 3D printing. STL is the industry standard format supported by all 3D printers.
Convert between formats for compatibility with different 3D modeling software. OBJ format provides universal compatibility across tools.
Convert 3D assets to GLB or GLTF for game engines like Unity and Unreal. These formats support animations, materials, and efficient loading.
Convert VOX files from MagicaVoxel to other formats, or convert standard 3D models to VOX for voxel-based editing and styling.
Convert PLY files from 3D scanners to other formats for editing and visualization. PLY format preserves color and point cloud data.
