Having images that are sized specifically for use on the web can help make your website’s appearance much better and also load faster than unoptimized images. Some things to take into consideration are the compression and format used on images as well as the size. Images should be exported to be the smallest size possible without any noticeable quality loss. The PNG (portable network graphics) format provides high quality resolution at lower file sizes. Images optimized for web will load quicker and have color palettes that are optimized for your browser. Also, many websites will have versions of images at double the resolution for use with Retina displays. Provide your web developer or designer with the images you want to use on your website to make sure that they are optimized for web use and will give your website visitors the best experience possible.
