A stocked computer cache may be convenient for logging into and out of go-to sites in seconds flat, but a major buildup of these tracking codes could significantly impact your PC’s performance. If you’ve noticed that your PC has been running rather slow of late, or you’re using a new browser and don’t know how to clear its cache, we’ve got you covered with the following guide.

What You Need

  • A PC

  • A web browser (such as Google Chrome, Opera, Safari, Firefox, or Microsoft Edge)

Why you might want to clear your cache

Clearing your browser’s cache can prove fruitful for several reasons. First off, purging the stored data in your cache forces your browser to seek and retrieve the most recent webpage elements instead of recycling the same old components, whether they’re up to date with the developer’s standards or not.

Furthermore, resetting your cache will potentially help in the event of 404, 502, and other errors that may result from a corrupt cache. You can also clear any private data you have stored in the form of login IDs, passwords, and additional sensitive info you’d prefer not to save on your machine. It’s also a simple trick you can employ to shed any unnecessary data, which could slow down your browser.

How to clear cache in Google Chrome

Step 1: Launch Google Chrome and select the Chrome Menu icon represented by three vertical dots in the upper-right corner of the browser window, and then choose Settings near the bottom of the resulting drop-down menu. (You may need to select the Down arrow first to access the Settings option).

Step 2: Then, select Privacy and security in the left sidebar. You’ll then want to look for the Clear browsing data option. Select it, and make sure the box for Cached images and files is checked. You can uncheck the other boxes for Browsing history, Download history, Cookies and other site data, and so on … unless you also want to delete these at the same time for privacy reasons.

Step 3: When ready, select Clear data to begin the process. If it’s been a while since you cleaned Chrome out, this step could take a long time, so schedule accordingly.

What’s the difference between a cache and cookies?

Another popular term that comes up when researching cache-clearing is “cookies.” While both your PC’s cache and its cookies are similar, they’re also a little different.

Cookies are bite-sized pieces of info that your browser stores to save things like passwords and page settings. A web cache is information that is stored about the sites you visit. This could be things like HTML coding and page images.

What happens after I clear my cache?

Clearing your cache is one of the best things you can do for the overall performance of your computer. If you’ve noticed that your PC has been running slow, there’s a good chance that clearing your cache will improve your speed. When you clear your cache, you may even notice websites you regularly visit start to load faster. Certain formatting problems you were having on sites may also be gone.

When you clear your cache, you may also wipe saved login info on certain websites. So before you go ahead and clear things, make sure you’ve written down any important usernames or passwords you may need.

How often should I clear my cache?

For optimal computer performance, it’s a good idea to clear your cache at least once or twice per month.

How to transfer photos from an iPhone to a computer
The Apple iPhone 15 Plus's gallery app.

As the old saying goes, the best camera is the one you always have with you. If you're like most iPhone users, that means you've likely amassed a sizeable collection of photos on your device. However, while Apple's Photos app is a great way to manage and view your photo library, it's never a good idea to keep all your eggs in one basket. After all, suffering a lost or broken iPhone is painful enough without also losing all your precious digital memories in the process.

Even if you're backing up your iPhone to iCloud or your computer, it's a good idea to keep your photos backed up separately. After all, opening a folder or a photo management app is a much easier way to get at your photos than trying to extract them from an iCloud or iTunes/Finder backup, which requires either restoring them to another iPhone or relying on special software tools.
