What is the typical resolution recommended for images used online?

The recommended resolution for images used online is typically lower than that for print, specifically at 72 dpi (dots per inch). This is because screens display images differently than printed media; a resolution of 72 dpi provides a good balance between quality and file size for online use. Images at this resolution tend to load faster, which is essential for providing a good user experience on websites where speed is crucial.

Higher resolutions, such as 150 dpi or 300 dpi, are unnecessary for online images because they result in larger file sizes that can slow down web page loading times without significantly improving the visual quality on most screens. Most digital displays do not require the higher detail that these resolutions provide, making 72 dpi the standard for web images.
