A raster image conveys digital data. There is a grid of pixels. Each pixel specifies the colour and location of a point.
This format is capable of displaying intricate details. It is compatible with most web browsers. Such images can be viewed on a screen. Or they can be printed on paper.
Raster images can depict complex realism. Examples are photography and painting.
However, enlarging raster images poses challenges. Pixelation leads to a blocky, jagged look.
Moreover, high-resolution raster files tend to be large. Thus requiring substantial storage capacity.
