Resolution 72 dpi

 72 dpi 

72 dpi is a low resolution used for printing and any other files. On 72 dpi the text on the image might appear fuzzy and the image pixelated. 72 is not good good for printing but is good for a website image. Resizing the image wont change the dimensions or size but it will change the printer outcome. A 300PPI image will be printed at a smaller size compared to the same image on 72PPI. 

DPI is dots per inch 

is commonly used in printers to spit out tiny dots and create images
