It depends on your business needs and goals. Selling digital art that is license-free can make it easier for customers to use and distribute your products, but it also means you may have less control over how your content is used.
On the other hand, choosing to sell clip art with a license can give you more control over how it’s used and potentially generate more revenue for your business. Consider your priorities and do some research on the pros and cons of each option to make the best decision for your business.
