What is DPI?
DPI is an important concept in image resolution
DPI (Dots Per Inch) refers to the number of dots or pixels per inch, which is a unit of measurement for image resolution. It represents the fineness of an image when printed or displayed.
DPI and Image Quality
The higher the DPI value, the more details the image contains, and the better the quality of the printed image. For example, a 300 DPI image will display more details when printed than a 72 DPI image.
Difference between DPI and PPI
DPI (Dots Per Inch) is typically used to describe the output resolution of a printer, while PPI (Pixels Per Inch) is used to describe the pixel density of a digital image. In everyday use, these two terms are often used interchangeably.
