If you build websites, chances are you have a strong opinion about what type of image format delivers the best possible user experience. You might believe that by loading images progressively, you improve perceived performance by showing the user something while they look at the screen. Or you could believe that watching an image load progressively increases user frustration. We took these assumptions to the neuroscience lab to see if we could definitively answer the question: which image format results in happier users?
There have been countless studies demonstrating the relationship between faster web pages and improvement to a vast array of business metrics. For most websites, images represent a huge untapped area of opportunity for optimizing performance as images comprise more than half of a typical page's weight. To make pages faster, site owners need to take advantage of every available image optimization technique.
