Commons:Donate to the public domain
From Wikimedia Commons, the free media repository
If you want to give up control over your work completely, you can donate it to the public domain. Unlike publishing it under a copyleft license, this does not ensure that derivative work remains free, and it does not require that you are credited. In fact, you lose all rights regarding your work (that is the meaning of "public domain").
You can donate your work to the public domain only if if does not contain, use or cite works by others, unless those works are in the public domain, too. See Commons:Licensing for details. To effectively put your work into the public domain, please tag it with {{PD-self}}, which will look like this:
Note that in some jurisdictions (like most of the European Union) it is not possible to truly donate to the public domain—that is what the second sentence in this template is for. To grant an unlimited license without the PD dedication, you may alternatively state clearly that you are the author and tag it with {{self|CopyrightedFreeUse}} (or short, {{self|CFU}}):
|
Of course, it is always possible to use a copyleft license that will ensure that all derivative work will also be free, and that you are credited as the author. There are several copyleft licenses acceptable on the Commons, see Commons:Copyright tags. The recommended way to license your work is a dual license of GFDL and CC-by-sa-2.0. To do this, use the tag {{self2|GFDL|cc-by-sa-2.0}}, which will look like this:
