What is a Raster Image?

A Raster Image is a type of digital image made up of a grid of individual pixels.

Each pixel in the grid has its own specific color or shade, which collectively forms the complete image. Raster images are ideal for rich, detailed graphics such as photographs. They are resolution-dependent, meaning their clarity depends on their pixel density; thus, resizing can affect their quality. When it comes to advertising, brands often use high-resolution raster images to ensure that visual ads maintain quality across various platforms and devices.
