Yes, you can use Storyblocks content in client projects as long as you follow the terms of your license and have the right licensing coverage. Our licensing requires that our assets must be incorporated into an original project in some way or they must be modified. As long as you meet one of those requirements, you can distribute the final project to clients.
Sharing or selling the unedited, original stock asset files from Storyblocks with a client is not permitted under our license. Each of our licenses outline the terms of use that they cover, including commercial projects and permitted distribution.
If you're still not sure about whether or not you’ll be covered, just ask!
