How to Increase Resolution of an Image?

Image resolution refers to how many pixels are displayed per inch of an image. The higher the resolution is, the more pixels per inch the image will contain, which makes it a high-quality image.

However, there are some users that are trying to increase the resolution of the image to get a better look at the details of the image. In this article, we will show you some methods that may help you in increasing the resolution.
