whst is mean by copyright free?

Answer 1

Images in the public domain, such as NASA imagery, would be copyright-free.

People often use "copyright-free" to describe the millions of images on Flickr that carry Creative Commons licenses, but this is technically incorrect. The images are still protected by copyright, they simply have extraordinarily broad licenses that allow many uses without further permission.

Answer 2

Materials that are "copyright free" are in the public domain. They may not have been eligible for copyright (for example, works of the federal government), protection may have expired, or they may have been donated to the public domain by the creators.

Answer 3

It simply means that a particular work is not copyrighted and is thus available to use however you'd like. For a list of copyright free resource sites check the related link.

Answer 4

Copyright free means that something is not protected by a copyright. This means that there are no restrictions on the use of whatever is copyright free.
