ply to gltf conversion describes export of polygon graphics (PLY format) to GLTF format, typically for the purpose of sharing / exchange of 3D model.
Blender is probably the most convenient choice for this, considering that it supports both formats, it's free and you can find tons of guides, tutorials and other materials that can help you with it on the Internet. But of course, the same should be also doable in other similar 3D modeling tools that can import PLY files. Last option would be to use one of the GLTF converters for this task.
