Royalty-free
Royalty-free means that after the initial purchase or license, the work can be used without paying recurring fees per use.
Royalty-free describes a licensing model where you pay once (or nothing) and may then use the asset repeatedly without owing additional royalties for each use. It does not mean free of cost — it means free of per-use fees.
Royalty-free is common for stock images, music, and 3D models. It still comes with conditions set by the license, such as limits on redistribution, so it is not the same as public domain.
License
A license is the legal permission a creator grants a buyer specifying how a digital product may and may not be used.
Commercial license
A commercial license grants the buyer the right to use a digital product in for-profit work, such as client projects or products sold for money.
Public domain
Public domain refers to creative work that is not protected by intellectual property rights and may be used freely by anyone for any purpose.
