What is the standard DPI resolution for images intended for web use?

The standard DPI resolution for images intended for web use is commonly recognized as 72 dpi. This resolution is based on historical conventions, where 72 dpi was chosen because it roughly corresponded to the pixel density of screens at the time. Although modern displays have varying pixel densities, 72 dpi remains a widely accepted standard for web images to ensure that they load quickly and display appropriately across various devices.

Images with 72 dpi are optimized for online viewing, allowing for faster loading times without significant loss of visual quality for the purposes of digital viewing. This resolution provides a good balance between file size and image clarity on screens, which is critical for maintaining user experience on websites and social media platforms.

While other resolutions like 150 dpi and 300 dpi are suitable for print media, they result in larger file sizes that can hinder performance when used on the web. This makes them less practical for online use, where speed and accessibility are paramount. Therefore, choosing 72 dpi for web images supports efficient web performance while still delivering satisfactory quality for digital consumption.
