It is possible to fix a pixelated image through the use of a photo editing program installed in a computer or available online. The essence of fixing such an image is to boost its quality so that viewers can benefit from it. Pixelation occurs when an image is expanded too much or compressed then expanded.
The process of fixing the pixelated image is also referred to as smoothing the image. This can be done through the use of a blur filter, which can help get rid of the harsh or jagged edges that are a result of pixelation. The filter will take the blurred image and then, by averaging the colors, smooth out any harsh edges. A sharpen filter can be used in order to fix the excessive blurriness, which comes as a result of blur filters.
