A ‘pixel’ (short for ‘picture element’) is a tiny square of colour. Lots of these pixels together can form a digital image.

The more pixels there are, the higher the image’s resolution. To improve a picture’s resolution, increase its size, then make sure it has the optimal pixel density. The result is a larger image, but it may look less sharp than the original picture.
