The cache is a storage location on your device where your browser keeps bits and pieces of websites. It stores images, fonts, HTML, CSS, JavaScript files, and more. When you visit a website for the first time, your browser downloads everything to display the page. Your browser saves cache in your memory. When you revisit the website, your browser displays the page quickly. However, it also takes up lots of space. Therefore, we explain how to clear the cache on Safari for iOS.

Part 1: What Is Safari Cache Data?

Safari cache temporarily stores web pages, images, JavaScript, data, and other information locally. If you browse the same web page next time, Safari will check the local cache and display the data directly without re-downloading it. According to developers, cache data can accelerate the load time and reduce the load on the server when you access websites.

If you browse websites frequently on Safari, the amount of cache data will accumulate as time goes by. That can bring serious problems, like YouTube videos not loading. Cache data may lead websites to load too slow. Moreover, it may occupy a large amount of space. Therefore, you'd better empty Safari cache from time to time.
