No. Everything runs in your browser - your file never leaves your device. How this is verifiable
OBJ (Wavefront) is a common 3D exchange format, while PLY (Polygon File Format / Stanford) is widely used by research tools, point-cloud software and meshing programs such as MeshLab or CloudCompare. This tool reads your OBJ and writes a clean ASCII PLY with a vertex list and a face list.
The output is ASCII PLY: a readable header (element vertex, element face) followed by the vertex coordinates and the faces as index lists. Faces keep their original number of corners. The coordinates are carried over unchanged, so the geometry is preserved exactly.
Everything runs entirely locally in the browser - your possibly confidential model never leaves your device. Honestly framed: pure geometry is transferred. OBJ material (MTL), textures and groups have no counterpart in a plain PLY and are not carried over. An invalid or empty OBJ file is rejected with a clear message.

PLY (Stanford Polygon Format) is widely used by research tools, 3D scanners and meshing software like MeshLab or CloudCompare.
ASCII PLY - a readable header plus a vertex list and a face list, easy to inspect and widely accepted.
No. A plain PLY stores geometry; OBJ material (MTL), textures and groups have no counterpart there.
No, the conversion happens entirely locally in the browser; your model never leaves your device.
