Firstly, mockups provide a realistic and tangible preview of how your design will look in its intended context, allowing you to make informed decisions and visualize the final result before production. They enable you to experiment with various color schemes, layouts, and design elements without committing to costly physical prototypes.

Mockups also aid in communication and collaboration, as they serve as visual references for clients and stakeholders, ensuring everyone is aligned on the design direction. Additionally, mockups save time and resources by streamlining the design iteration process and reducing the need for extensive revisions. Ultimately, mockups enhance efficiency, creativity, and accuracy in design, leading to exceptional end products.
