What typically happens to the quality of an image when its DPI decreases?

When the DPI (dots per inch) of an image decreases, the quality of the image generally decreases and can appear pixelated. DPI is a measure of the resolution of an image, indicating how many dots of ink or pixels are present in a one-inch square. A lower DPI means there are fewer dots or pixels available to represent the image, leading to a loss of detail and clarity.

As you reduce the DPI, the image becomes less capable of displaying fine details, resulting in a more blocky or blurry appearance. This phenomenon occurs because the image is now made up of larger visible pixels, which can cause it to 'pixelate,' appearing uneven or distorted when viewed at the same size as a higher DPI image. Therefore, decreasing the DPI directly correlates with a reduction in image quality.
