UnitConDigital Image Resolution
Image resolution describes how densely pixels or print dots are packed. PPI is usually used for digital images and screens, while DPI is more often used for print output, though the terms are often mixed in practice. This converter helps compare image density across screen and print workflows. It is useful for designers, photographers, and publishers.

Frequently asked questions
DPI means dots per inch and is usually associated with print output. It describes how densely a printer places dots on paper.
PPI refers to pixels in a digital image or display, while DPI refers to printed dots. In casual use people often blur the terms, but technically they are different.
High-quality print work commonly targets around 300 DPI at final size. Lower values may work for large-format pieces viewed from farther away.
Web images are primarily controlled by pixel dimensions, not print DPI. For screens, the actual displayed size depends more on CSS and device pixel density.
