Compression ratio seems 95%, but there is a lot of white space in the
picture. I wonder what kind of compression PNG use?

The most complicated compression probably has JPEG, but it was
originally designed by photographers for photographers. Also it may
come as odd to to see zipped JPEG, as JPEG is already compressed
format.
