Dots per inch (DPI) is a measurement of the resolution of an image. It refers to the number of individual dots that make up one inch of an image. The higher the DPI, the higher the resolution and the sharper the image will appear. DPI is an important consideration for both print and digital images.
DPI becomes particularly important when printing images. A higher DPI will result in a sharper, more detailed print. For example, an image with a DPI of 300 will produce a sharper print than an image with a DPI of 72. However, it is important to note that a higher DPI will also result in a larger file size.
