We have all dealt with it: a website suddenly stops loading right, a login button refuses to work, or an online video keeps buffering forever. When your browser starts acting up, the most common advice you will hear is to “clear your cache and cookies.”
But what does that actually mean, and why does it fix so many weird internet bugs? More importantly, how do you do it without accidentally wiping out all your saved passwords?
Here is a simple, straightforward guide to cleaning out your Google Chrome browser on both your computer and your phone.
What are Cache and Cookies Anyway?
Every time you visit a webpage, your browser saves tiny bits of information to make your next visit faster.
- The Cache: Think of this as a local copy of a website’s images, fonts, and layout. Instead of downloading a site’s heavy logo every single time you click a page, Chrome just grabs it from your computer’s hard drive to save time.
- Cookies: These are small text files that remember you. They keep you logged into your accounts, remember what items you left in a shopping cart, or save your site preferences (like dark mode).
Why do you need to clear them?
Websites update their code all the time. If a site updates its layout but Chrome is still trying to load the old version stored in your cache, the website will look broken or crash. Clearing them forces Chrome to download a fresh, brand-new copy of the site.
How to Clear Cache and Cookies on a Desktop (Windows or Mac)
The fastest way to get to the cleanup menu on a computer is with a quick keyboard shortcut.
- Open Google Chrome.
- Press Ctrl + Shift + Delete if you are on Windows, or Cmd + Shift + Delete if you are on a Mac.
- A settings tab called Clear browsing data will pop up on your screen.
- Look at the Time range dropdown menu at the top. If you just want to fix a recent bug, choose Last hour or Last 24 hours. If you want a deep clean, choose All time.
- Check the boxes next to Cookies and other site data and Cached images and files.
- Important Tip: Make sure the box next to “Passwords and other sign-in data” is unchecked so you don’t lose your saved logins!
- Click the blue Clear data button.
How to Clear Cache and Cookies on Chrome Mobile (iPhone or Android)
If Chrome is running sluggishly on your smartphone, you can clear out the junk files through the mobile app settings.
- Open the Chrome app on your phone.
- Tap the three dots icon (located in the bottom right corner on an iPhone, or the top right corner on an Android).
- Scroll through the menu and tap Clear Browsing Data.
- Choose your preferred Time Range (like Last 7 Days or All Time).
- Tap the circles next to Cookies, Site Data and Cached Images and Files so they are checked.
- Tap the red Clear Browsing Data button at the bottom of the screen to confirm.
Quick Reference: What Gets Deleted?
| Data Type | Will it log you out of websites? | Does it delete saved passwords? | Does it free up storage space? |
| Browser Cache | No | No | Yes (Often hundreds of megabytes) |
| Cookies | Yes (You will need to sign back in) | No (Unless you check the password box) | No (These are tiny text files) |
| Browsing History | No | No | No |
How Often Should You Do This?
You do not need to clear your cache and cookies every single day. Doing it too often actually slows down your browsing experience because your computer has to re-download every single image and font from scratch.
Instead, only clear them out when a specific website is acting glitchy, or every few months just to keep your device clutter-free.
