A loop is a visual shortcut
A refresh icon compresses a sequence into a shape. The arrows travel around a circle, so the eye reads “go through this again”: the browser returns to the page and rebuilds its view. That loop is easy to recognize even when there is no room for a label.
The resemblance to recycling comes from the shared visual idea of circulation, not from the page being recycled. Recycling symbols represent material moving through a reuse cycle; a refresh symbol represents an action repeating. The browser’s arrows are about time and repetition, not what happens to the page’s contents.
What happens when you click
The browser repeats the work of loading the page. It may request the page’s data from the website and retrieve supporting pieces such as images and scripts. Some of those pieces can come from the browser’s temporary storage, called a cache, rather than being downloaded again. The browser then uses the available pieces to display the page anew.
So the icon is an imperfect but useful metaphor: it signals a fresh pass through loading, not a literal return to the exact same starting point. Its circular motion makes that abstract command legible at a glance—while accidentally dressing it in the visual language of recycling.
