This is a common and reasonable question. The short answer is: it depends on how you use the image. Here's what you need to know.
Who owns Gemini-generated images?
Under Google's Terms of Service, you retain rights to the images you generate with Gemini, subject to those terms. Google grants you a license to use, reproduce, and share your outputs.
Is watermark removal itself illegal?
In most jurisdictions, removing a watermark from content you legally own or have rights to is not illegal. The concern arises when watermark removal is used to misrepresent ownership of content you don't have rights to.
