Many are unaware of the key differences between a print resolution and web resolution. When it comes to the resolution of an image, it refers to the density of the pixels (or printed dots) that constitute it. Images with a high resolution are crisp and vividly detailed. However, if the resolution is decreased or the image is enlarged too much, it will lose the detail and you will notice blocky squares of the pixels.
There are distinct differences between screen resolution and print resolution. Screen resolution is measured in pixels per inch (PPI) and print resolution is measured in dots per inch (DPI). For web safe images, you want to have a resolution of 72-100 PPI. For images in print, you must have a resolution of 300 DPI.
You do not want to have a high resolution image for the web for numerous of reasons. The main reason is, it will slow down your website significantly. Depending on how fast the internet is for the visitor of your website, they may not want to stay on your website for long if the website takes too long to load.
