What clearing your cache does and why you might need to

Cache is temporary storage your browser keeps on your computer — copies of images, scripts, and other page elements from websites you visit. The next time you return to that site, your browser loads these copies from your hard drive instead of downloading them again, which makes pages load faster.

Over time, cache builds up and takes up disk space. More importantly, cached versions can become outdated. If a website changed its design or fixed a bug, you might still see the old version because your browser is showing you what it stored weeks ago. Clearing cache forces your browser to read fresh copies of everything the next time you visit, which solves display problems, speeds up a sluggish browser, and frees up storage space on your device.

You do not need to clear cache constantly — once every month or two is normal for most people. But if a website looks broken, loads slowly, or behaves strangely, clearing cache is one of the first things to try.

Key Takeaways

  • Cache is a copy of website files stored on your computer that makes pages load faster, but outdated cache can cause display problems.
  • Clearing cache removes these stored files and forces your browser to read fresh versions next time you visit a site.
  • The steps to clear cache differ between browsers — Chrome, Firefox, Safari, and Edge each have their own menu path.
  • You can choose to clear cache from just today, the last week, the last month, or all time, depending on how far back you want to go.
  • Clearing cache will log you out of most websites, so have your passwords ready or use a password manager before you start.

Clear cache in Chrome

Open Chrome and look at the top right corner. Click the three vertical dots (called the menu button) and select Settings. On the left side, click Privacy and security, then click Clear browsing data.

A window will pop up. At the top, you will see a dropdown that says Time range. Click it and choose how far back you want to clear — All time removes everything, while Last 24 hours removes only today's cache. Make sure the box next to Cached images and files is checked. You can leave the other boxes unchecked unless you also want to remove cookies or browsing history. Click Clear data and wait a few seconds for it to finish.

Clear cache in Firefox

Open Firefox and click the menu button (three horizontal lines) in the top right corner. Select Settings, then click Privacy & Security on the left side. Scroll down to the section labeled Cookies and Site Data. Click the button that says Clear Data.

A small window appears. Make sure Cached Web Content is checked and Cookies and Site Data is unchecked (unless you want to remove those too). Click Clear. Firefox will clear the cache when ready and close the window.

Clear cache in Safari

Open Safari and click Safari in the menu bar at the very top of your screen (not inside the browser window). Click Settings, then click the Privacy tab. Look for the button labeled Manage Website Data and click it.

A list of websites appears. Click Remove All at the bottom right to clear cache from all sites at once. If you want to remove cache from only specific websites, click each one in the list and then click Remove. Click Done when finished.

Clear cache in Microsoft Edge

Open Edge and click the three dots in the top right corner. Select Settings, then click Privacy, search, and services on the left. Under the section Clear browsing data, click the button that says Choose what to clear.

A window opens with a Time range dropdown at the top. Select how far back you want to clear. Check the box next to Cached images and files and uncheck the others unless you want to remove those too. Click Clear now and wait for the process to finish.

What to expect after clearing cache

The first time you visit a website after clearing cache, it will load slightly slower than usual because your browser has to read all the files fresh. This is normal and only happens once per site. After that first visit, cache rebuilds and pages load at normal speed again.

You will also be logged out of most websites. When you visit a site you normally log into, you will see the login screen instead of your account. This happens because login information is often stored in cookies, which are separate from cache but are cleared at the same time in most browsers. Have your passwords ready, or if you use a password manager like Bitwarden or 1Password, it will fill them in automatically.

When to clear cache versus when not to

Clear cache if a website looks wrong, buttons do not work, pages load slowly, or you see an error message that persists even after refreshing. It is also worth clearing if your browser feels sluggish or if you are running low on storage space.

You do not need to clear cache before every browsing session or every time you close your browser. Clearing cache too often actually makes browsing slower because your browser has to re-read files more frequently. Once a month is a reasonable schedule for most people. If you want cache cleared automatically when you close your browser, you can turn that on in your browser settings — look for an option like "Clear cache on exit" or "Clear browsing data on close."

Frequently Asked Questions

Will clearing cache delete my passwords or saved information?

Cache and cookies are different things. Clearing cache removes only temporary copies of images and page files. Passwords and saved form information are usually stored in cookies, which are cleared separately. If you want to keep passwords but clear cache, uncheck the "Cookies" box before clicking clear.

What is the difference between cache and cookies?

Cache stores copies of images, scripts, and other files to make pages load faster. Cookies store small pieces of information like login details, preferences, and tracking data. Both are temporary storage, but they serve different purposes. You can clear one without clearing the other in most browsers.

Can I clear cache for just one website instead of all websites?

Most browsers do not have a built-in way to clear cache for a single site. Safari is the exception — you can select individual websites in the "Manage Website Data" window and remove them one at a time. For other browsers, you would need to clear all cache or use a browser extension designed for this purpose.

Why does a website still look wrong after I cleared cache?

If clearing cache does not fix the problem, the issue is likely not with your browser's storage. Try refreshing the page by pressing Ctrl+R (or Cmd+R on Mac), or try the website in a different browser to see if the problem is specific to one browser. If the site still looks wrong everywhere, the problem is on the website's end, not yours.

Does clearing cache make my browser faster?

Clearing cache frees up storage space and can make your browser run faster if it was struggling with a very large cache. However, it also means your browser has to re-read files the next time you visit sites, which temporarily makes those sites load slower. For most people, the speed benefit is small unless your cache had grown very large.
