It's hard to understand complex licenses that is why all photos on Pexels are licensed under the Creative Commons Zero (CC0) license. This means you can copy, modify, distribute and perform the photos. The pictures are free for personal and even for commercial use. All without asking for permission or setting a link to the source. So that attribution is not required. All in all the photos are completely free to be used for any legal purpose.
The CC0 license was released by the non-profit organization Creative Commons (CC). Get more information about the license on the official license page.
Identifiable people may not appear in a bad light or in a way that they may find offensive, unless they give their consent.
Currently we cover over 2,000 photos. And every week at least 70 new high resolution photos will be added. All photos are hand-picked from free image sources. We make sure all published pictures are high-quality and licensed under CC0. Only creative commons photos from reliable sources like Unsplash, Gratisography, Little Visuals and many more are added to our photo database.
