No quality loss of course?

SmallJoker commented 6 years ago

There is no quality loss in the textures, but a loss of metadata information due to -strip all. Since the textures are documented and licensed as WTFPL anyway, this metadata is superfluous. In some cases stripping this information reduced the file size by 20% since they are only a few hundred bytes big.
