Creative Commons (CC) licenses are a way for creators to release rights to others.
Without these licenses, copyright assumes "all rights reserved." CC licenses, in comparison, might be considered "some rights reserved." Which rights are reserved depends on the type of CC license applied.
All CC licenses require a detailed attribution.

This element is part of every CC license. It requires that any use of the material gives credit to the creator.
This element disallows commercial uses of a work.
This element requires that adaptations are shared under the same terms.

These licenses are legally binding agreements. Failing to respect the terms of a license is a copyright violation and may have serious consequences.
Note: The most current version of these licenses is 4.0. You may encounter previous versions. These are still applicable and enforceable but not recommended for new works.

This page focuses on the human-readable layer of CC licenses. The icons and common deeds help everyday people easily communicate usage permissions.
There are two other important layers that make these licenses work.
The legal code fully explains each license and also makes them enforceable. It also helps bridge gaps to make these licenses internationally applicable. For example, check out the detailed legal code behind CC BY 4.0.
The machine-readable version of the license makes it possible to search and filter for openly licensed material. This can be accomplished using CC Rights Expression Language (CC REL). Many online platforms have incorporated this into their coding, making it easy for users to select the appropriate license and automatically apply a machine-readable license, but if you are publishing CC licensed material on your own website consider how you can incorporate this layer to improve findability.

Creative Commons also offers two other tools to facilitate openly sharing materials. These are not licenses.
CC Zero is a tool for creators to dedicate their work to the public domain, renouncing any copyright claim. CC0 enables others to distribute, remix, and adapt a work with no conditions. This is a "no rights reserved" approach, in contrast with the "some rights reserved" approach of the CC licenses listed above.
CC0 legal code has a license that enacts if renouncing rights is not valid in a certain country. It also has a promise that the creator will not pursue any legal action in conflict with their intention to release rights. This thoughtfulness makes it very protective for all involved no matter where they may be in the world.
This icon asserts a work has no copyright restrictions in any jurisdiction and is in the public domain. It does not release any rights, should they still exist.
CC licenses work with copyright, allowing rights holders to share their works on their own terms. That also means that all exceptions and limitations to copyright apply. For example, a small portion of CC BY-NC material can be used for commercial purposes under a Fair Use exception. When the copyright term expires on a CC licensed work, it enters the public domain just like any other work and no longer requires attribution or any other licensing elements.
