Mockups are digital or physical prototypes or representations of a design concept, typically used in the fields of graphic design, web design, and product design. They are created to provide a realistic preview or simulation of how a final design will look when implemented.

Mockups serve as visual aids that help designers and clients visualize the overall design, layout, and composition of a project. They can be used to present ideas, gather feedback, and make informed decisions before moving forward with the actual production or development process.

In graphic design, mockups often involve placing a design onto a digital or physical template, such as a business card, brochure, or packaging. This allows designers to see how the design will appear in its intended context, including factors like scale, proportions, and visual impact.

Product designers utilize mockups to visualize how a physical product will look and feel in real life. This can include creating 3D models or digital renderings that showcase different angles, materials, textures, and lighting conditions.

Mockups are valuable tools throughout the design process. They enable designers to iterate, refine, and improve their designs based on feedback and user testing. They also aid in effective communication between designers, clients, and stakeholders, ensuring that everyone has a clear understanding of the design concept before moving forward.
