PNG is the format almost anything will open, and it keeps transparent areas the way WEBP does. The picture comes across at the same width and height with nothing further discarded, which is also why the PNG usually ends up larger than the WEBP it came from. Both sizes are printed when the conversion finishes.

Nothing further is lost. The PNG holds the pixels as your browser decoded them, at the same size. Detail the WEBP itself already threw away cannot come back, though. A lossy WEBP stays as lossy as it was.
Because PNG keeps every pixel, while most WEBP files got small by discarding detail. The page prints both sizes when it finishes, so you can see what the difference is on your own file rather than guess.
Yes. Nothing is painted behind the picture, so transparent pixels stay transparent. That is the difference between this and converting to JPG, where those areas come out white.
Only one frame comes through. The picture is drawn onto a canvas once rather than stepped through, and a PNG file holds a single image.
