PPI stands for "pixels per inch."

PPI stands for "Pixels Per Inch", which is a measure of the amount of pixels that are packed into one inch of screen space. Essentially, PPI determines the display density of an electronic device like a computer monitor or smartphone screen. Higher PPI means that the display has more pixels per inch, therefore leading to a sharper and clearer image. PPI is an important consideration for anyone looking to purchase a new device, especially if they plan on working with high-resolution images or videos.
