Is Your Internet Slowing Down? Why Deleting Cookies and Cache Actually Works
Anyone who uses a computer or smartphone regularly in the US has run into this: websites load slowly, pages fail to display correctly, or certain features just stop working. Whenever you Google a fix, “Clear your cookies and cache” pops up as the top recommendation. But how does this simple trick actually make your device faster, and what’s happening under the hood?
Imagine you’re trying to check out on Amazon and the payment page won’t load, or you’re reading the news on The New York Times and images are missing. These are common situations in which excess cookies and cache can cause trouble. In fact, support pages from Google, Microsoft, and Apple all list this as a first troubleshooting step.
This article breaks down why clearing cookies and cache can noticeably speed up your browsing experience—using real-life examples and plain English, tailored for US readers.
What Are Cookies and Cache, Really?
Cookies: The Web’s Memory for Your Preferences
Cookies are small text files saved by websites in your browser. They store things like login info, user settings, and what you added to your shopping cart, making your next visit smoother and more personalized.
Cache: Storing Temporary Data for Faster Loading
The cache is where your browser keeps images, code, fonts, and other elements from sites you visit often. This speeds up future visits, but when outdated or too much cache builds up, it can backfire and slow things down instead.
Why Do Cookies and Cache Cause Problems?
1. Slower Website Loading Over Time
Excess cookies and cache force your browser to sift through unnecessary data each time you load a page, slowing down the process. For people who open lots of tabs or haven’t cleared data in months, this effect is even more pronounced.
2. Pages Display Incorrectly or Features Don’t Work
Outdated cache files can cause site layouts to break or prevent buttons and payment systems from working. For example, major US banks and e-commerce platforms like Walmart often advise clearing cache when users report technical issues.
3. Increased Security and Privacy Risks
Cookies can contain sensitive data—like your login sessions or autofill information. If left for too long, these files can create vulnerabilities, especially on shared or public devices. US cybersecurity organizations recommend regular cookie management as a best practice.
4. Wasted Storage Space
If cookies and cache accumulate, they take up valuable disk space—which matters most on older laptops or budget smartphones where storage is limited. This can cause system slowdowns, not just in your browser but across the device.
How Much Faster Will My Computer Get?
Real-World Results and Expert Opinion
According to guidance from Microsoft and Google, clearing cookies and cache can significantly speed up browser performance. For instance, users who haven’t cleared cache in over a year have reported websites loading up to 30% faster after a cleanup.
Cybersecurity experts from the National Institute of Standards and Technology (NIST) also note that “regularly deleting cookies and cache not only prevents technical issues, but also reduces security risks for average users.”
What to Know Before You Delete
You’ll Lose Auto-Login and Site Preferences
When you clear cookies, you’ll need to re-enter your passwords, reset saved carts, and set preferences again on sites like Netflix or Amazon. Using a password manager app (like LastPass or 1Password) can help keep things seamless.
You Can Choose What to Delete
Most US browsers—Google Chrome, Safari, Edge, and Firefox—let you delete all data or target specific sites. This means you can keep your bank login info while clearing problem data from a buggy site.
Step-by-Step: How to Clear Cookies and Cache (Chrome Example)
- Click the three-dot menu in the top-right of Chrome
- Go to ‘Settings’ → ‘Privacy and security’
- Click ‘Clear browsing data’ and check ‘Cookies and other site data’ and ‘Cached images and files’
- Hit ‘Clear data’ to finish
Safari, Edge, and Firefox all have similar options under their privacy settings—look for “Clear Data” or “History.”
