What is Image Resolution?

In the world of digital images, image resolution is a way of measuring the number of details present in an image. While there are different ways of measuring the image resolution, the most important factor for quantifying this resolution is PPI. PPI refers to the number of pixels per inch of an image. For example, 800 PPI means there are 800 pixels in one inch of the image. More pixels mean a better image.

Why Do I Need to Increase Resolution of Image?

You need to increase the resolution of an image to improve image quality. Higher resolution images are sharper and crisper images. If an image has a higher resolution, you can enlarge different parts of the image and observe finer details within it. Lower resolution images tend to be blurry and of poor quality.
