What cache and cookies actually do
Cache is a folder on your computer where your browser stores copies of images, videos, and code from websites you visit. When you go back to that site, your browser loads the cached copy instead of downloading it again — the page loads faster because it does not have to fetch everything from the internet.
Cookies are small text files that websites save on your device. They remember things about you: your login status, items in your shopping cart, your language preference, or what you searched for last time. When you return to the site, it reads the cookie and knows who you are without asking you to log in again.
Both exist to make browsing faster and more convenient. But they also take up storage space on your device, and cookies can track your activity across websites. Clearing them periodically is a normal maintenance task — it does not break anything, and your browser will rebuild the cache as you browse normally.
Key Takeaways
- Cache stores website images and code to make pages load faster; clearing it frees up storage but does not affect your passwords or saved information.
- Cookies remember your login status and preferences; clearing them logs you out of websites and removes tracking data.
- The steps to clear both are built into your browser settings and take less than a minute.
- You can set your browser to clear cache and cookies automatically when you close it, or clear them manually whenever you want.
How to clear cache and cookies in Chrome
Open Chrome and click the three vertical dots in the top right corner. Select Settings from the menu. On the left side, click Privacy and security, then click Clear browsing data.
A window will pop up. At the top, make sure the time range is set to All time if you want to clear everything, or choose a specific range like Last hour or Last 7 days. Check the boxes next to Cookies and other site data and Cached images and files. Leave other options unchecked unless you have a specific reason to clear them. Click Clear data.
Chrome will clear the selected items and close the window. You are done. The next time you visit a website, Chrome will start building a new cache.
How to clear cache and cookies in Firefox
Open Firefox and click the three horizontal lines in the top right corner. Select Settings. On the left, click Privacy & Security. Under the Cookies and Site Data section, click Clear Data.
A window will appear with two checkboxes. Make sure both Cookies and Site Data and Cached Web Content are checked. Click Clear. Firefox will remove both items when ready.
Alternatively, you can use the keyboard shortcut Ctrl+Shift+Delete (Windows) or Command+Shift+Delete (Mac) to open the clear data window directly.
How to clear cache and cookies in Safari
Open Safari and click Safari in the menu bar at the top of your screen. Select Clear History. A dropdown menu will appear asking how far back you want to clear — choose All history to remove everything, or pick a specific time range.
Click Clear History. Safari will clear your browsing history, cache, and cookies in one action. Unlike Chrome and Firefox, Safari does not let you clear cache and cookies separately — clearing history removes all three together.
How to clear cache and cookies in Edge
Open Microsoft Edge and click the three dots in the top right corner. Select Settings. On the left, click Privacy, search, and services. Under Clear browsing data, click Choose what to clear.
A window will open. Set the time range to All time or your preferred range. Check the boxes for Cookies and other site data and Cached images and files. Click Clear now. Edge will remove both items and confirm when it is finished.
Set your browser to clear automatically
Instead of clearing manually each time, you can tell your browser to clear cache and cookies automatically whenever you close it. This happens in the background without you having to do anything.
In Chrome: Go to Settings, click Privacy and security, then turn on Clear cookies and site data when you quit Chrome. In Firefox: Go to Settings, click Privacy & Security, scroll to Cookies and Site Data, and check Delete cookies and site data when Firefox is closed. In Safari: Click Safari in the menu bar, select Settings, click the Privacy tab, and check Remove history items, then choose after one day or your preferred timeframe. In Edge: Go to Settings, click Privacy, search, and services, and turn on Clear browsing data under Clear browsing data.
Once enabled, your browser will handle the clearing automatically. You will be logged out of websites when you close and reopen your browser, but your passwords and saved information will remain intact.
What clearing cache and cookies does and does not do
Clearing cache and cookies does not delete your saved passwords, autofill information, or bookmarks — those are stored separately. It does not affect your browser extensions or settings. It does not remove your browsing history unless you specifically clear that too. And it does not make you anonymous online or stop websites from tracking you in the future.
What it does do: frees up storage space on your device, logs you out of websites, removes cookies that track your activity, and forces your browser to read fresh copies of website files the next time you visit. If a website is loading slowly or acting strangely, clearing cache and cookies is often the first troubleshooting step.
Frequently Asked Questions
Will clearing cache and cookies delete my passwords?
No. Passwords are stored separately from cache and cookies. When you clear cache and cookies, you will be logged out of websites, but your saved passwords remain in your browser. The next time you visit a site, you can log back in and your password will autofill.
Why do I get logged out after clearing cookies?
Websites use cookies to remember that you are logged in. When you clear cookies, that memory is erased, so the website no longer knows who you are. You will need to log in again, but this is normal and expected.
How often should I clear my cache and cookies?
There is no set rule. If you browse heavily or are concerned about tracking, clearing weekly or monthly is reasonable. If storage space is tight on your device, clearing more often helps. Many people set it to clear automatically when they close their browser and never think about it again.
Does clearing cache make websites load slower?
Temporarily, yes — the first time you visit a site after clearing cache, your browser has to read all the images and code again instead of using cached copies. But this usually takes only a few extra seconds, and the cache rebuilds as you browse. The performance difference is rarely noticeable.
Can I clear cache and cookies for just one website?
Yes. In Chrome, Firefox, and Edge, you can right-click on any website and select an option like Delete or Remove to clear data for just that site. This is useful if one site is misbehaving but you want to keep cache and cookies from everywhere else.
