You're browsing the web on youriPhone, reading about where you can preorder the iPhone 16afterApple's Glowtime eventwhen you notice that things look a little off. Images are misshapen, some information is missing. You might be wondering what's going on.
Instead, you should be asking: When was the last time you cleared your cache?
Your browser cache stores website data for faster retrieval, which can keep things a little snappier when everything matches up. Over time page elements might change -- the site might add new images, change layouts, etc. -- and that's when problems can pop up.
You can think of your browser cache as a mini fridge. It's a place where you can store items for the convenience of easier retrieval -- you don't need to trek all the way back to the kitchen for every item. That mini fridge gets cluttered over time, to the point where it might be difficult to find what you want or the items in the fridge have gone bad. That's why it's good to clear out your cache (and your actual fridge) every so often.
Whether you useChrome, Safari or other browsers on your iPhone, your cache builds up that digital clutter over time. Clearing your cache gives the browser a new start, which can speed up your web surfing, even oniOS 17or the upcoming iOS 18. (If you're trying to get your phone to run faster, trymanaging your iPhone's storage.)
Website cookies are similar, except they store information about user data, rather than data on the website itself. Clearing your cookies gives you a chance to reset those preferences, which could improve your browsing experience. Note that clearing your cache and cookies will log you out of sites, which means you'll have to log into them again and reset any preferences. The up-front investment of that time can lead to a smoother experience down the road, and it can be a useful fix if you've recently changed settings that aren't being applied properly.
Here are step-by-step guides on how to clear your cache on your iPhone based onthe browser you use.

What happens when you clear the cache?
Clearing your cache removes the website data your phone stored locally to prevent having to download that data upon each new visit. The data in your cache builds over time and can end up slowing things down if it becomes too bulky or out of date. (My phone had about 150MB of data stored in Chrome when I checked.) Clearing that data gives sites a fresh start, which may fix some loading errors and speed up your browser. Clearing your cache also signs you out of pages, so be prepared to sign in to everything again.
How often do I need to clear my cache?
Most people only need to clear their caches once every month or two. That's generally the point when your browser will build up a cache large enough to start slowing things down. If you frequent a large number of sites, you should err on the side of clearing your cache more often.
