The PNG format is *not* lossy.  From

      http://www.w3.org/Graphics/PNG/

  """PNG is an extensible file format for the lossless, portable,
  well-compressed storage of raster images. PNG provides a patent-free
  replacement for GIF and can also replace many common uses of
  TIFF. Indexed-color, grayscale, and truecolor images are supported,
  plus an optional alpha channel for transparency. Sample depths range
  from 1 to 16 bits."""
