}This tool allows users to overlay a personal photo onto a template designed to resemble a California driver’s license. It automatically populates the template with customizable information such as name, date of birth, and address, while applying various graphical elements like watermarks, security patterns, and signature styles. This tool can be used for creative projects, role-playing games, or as a placeholder for digital identity mockups in design prototypes.
