Your converted GLTF files will appear in the destination folder as soon as processing completes.
Before you convert PNG to GLTF
PNG is made of pixels and GLTF is a geometry format, so the two describe images in fundamentally different ways. Check the result before sending it downstream: what matters is whether the output contains editable geometry or a picture placed inside a GLTF container, and that determines whether a CAD or design tool can work with it.
