Common questions about using this tool — answered.
DPI (dots per inch) determines print quality. 300 DPI is the standard for high-quality photo prints — required by passport authorities and official document processors. A 300 DPI photo looks sharp when printed. Most digital devices capture photos at 72 DPI by default, which can appear blurry when printed.
