Image resolution refers to the amount of detail and clarity present in a digital image. It indicates how many pixels are contained in the width and height of the image.

In the field of graphic and web design, image resolution is important as it determines the quality and sharpness of an image. A high resolution means that there are more pixels in the image, resulting in a finer representation and more detail. High-resolution images are well suited for printing or for use on high-resolution displays.

On the other hand, too high a resolution can also lead to larger file sizes, which can slow down the loading time of websites. It is therefore important to adjust the image resolution according to the intended use. For web design, lower resolution images are often used to enable faster loading times without losing too much detail.

Choosing the right image resolution is crucial to ensure that images can be displayed in the best possible quality both online and offline.
