As a creator you can also explicitly dedicate a piece of work to the public domain, thus relinquishing any copy right to it. That’s what licenses like CC0, WTFPL, and The Unlicense do.
However, even being in the public domain does not in itself mean you can do everything. For example, in France you still have to respect the “moral rights” of the author, meaning you have to include their name and original title.
The "moral rights" in France and Germany, or the "Urheberrecht" in Germany and Austria and others in Europe prohibit even the creator to put things in the "public domain" to the full extend. There are pro and con debates about this, of course.
