GLBKit supports selected 3D model formats depending on the specific tool being used. The format converter reads GLB, glTF, OBJ, FBX, STL, PLY, 3MF and OFF files, and also accepts a ZIP archive containing a model together with its companion files. The viewers additionally open USD, DAE, X3D, VRML, VRM, STEP, PCD, LAS and LAZ files. Support can vary by tool, and the formats listed for each tool page are the ones that tool accepts.
Not every combination is offered. The converter exports to GLB, glTF, OBJ, FBX, STL, PLY, 3MF and OFF, and the targets available to you depend on the source format you select. For example, PLY point-cloud sources convert to a narrower set of targets than mesh sources do. USD, STEP, PCD, LAS and LAZ files are viewer-only and are not offered as conversion targets.
File compatibility may vary depending on the structure of the model, geometry, materials, textures, scenes, metadata, and other characteristics of the uploaded file.
