What clearing YouTube cache does and why you might need to

Clearing your YouTube cache removes temporary files that the app or website stores on your device to load videos faster. Over time, these files pile up and can slow down YouTube, cause videos to buffer, or make the app crash. Clearing the cache does not delete your watch history, subscriptions, or saved playlists — it only removes the temporary data YouTube uses behind the scenes.

You might notice YouTube running slowly after weeks of watching, or the app might freeze when you try to play a video. These are signs the cache has grown too large. Clearing it is one of the first things to try before uninstalling and reinstalling the app, which takes much longer.

Key Takeaways

  • Clearing YouTube cache removes temporary files but keeps your watch history, subscriptions, and playlists intact.
  • On Android phones, go to Settings > Apps > YouTube, tap Storage, then select Clear Cache.
  • On iPhones, you must delete and reinstall the YouTube app, since iOS does not let you clear cache for individual apps.
  • On a computer, clearing your browser cache will also clear YouTube cache if you watch through a web browser.
  • After clearing cache, YouTube may take a few seconds longer to load videos the first time, then speed up again.

Clearing cache on an Android phone

Open your phone's Settings app and scroll down to find Apps or Application Manager — the exact name depends on your phone brand. Tap it, then search for or scroll to YouTube. Tap YouTube to open its details page.

Look for a button or option labeled Storage or Storage and Cache. Tap it. You will see two options: Clear Cache and Clear Data. Tap Clear Cache only. Do not tap Clear Data, which would delete your login information and settings. After you tap Clear Cache, the app will confirm the action is complete. Close Settings and open YouTube again — it will work normally, but may load slightly slower the first time as it rebuilds the cache.

Clearing cache on an iPhone

iPhones do not have a built-in way to clear cache for individual apps. Instead, you must delete the YouTube app and reinstall it. Press and hold the YouTube app icon on your home screen until a menu appears, then tap Remove App. Choose Remove from Home Screen if you want to keep it in your app library, or Delete App if you want to remove it completely. Confirm by tapping Delete.

Open the App Store, search for YouTube, and tap Get, then Install. Sign in with your Google account when prompted. Your watch history and subscriptions will reappear because they are stored on Google's servers, not on your phone. This process takes a few minutes but is the only way to clear YouTube cache on iOS.

Clearing cache in a web browser on Windows or Mac

If you watch YouTube through a web browser like Chrome, Firefox, or Safari, clearing your browser cache will also clear YouTube cache. The steps differ by browser, but the idea is the same: open your browser settings, find the option to clear browsing data, and select the cache option.

In Chrome, press Ctrl+Shift+Delete on Windows or Command+Shift+Delete on Mac. A window will open. Make sure the time range is set to All Time, check the box next to Cookies and Other Site Data and Cached Images and Files, then click Clear Data. In Firefox, press Ctrl+Shift+Delete or Command+Shift+Delete, check Cache, and click Clear Now. In Safari on Mac, go to History > Clear History, choose All History, and click Clear History. After clearing, YouTube will load normally the next time you visit.

What to expect after clearing cache

The first time you open YouTube after clearing cache, it may take a few extra seconds to load videos or show your recommendations. This is normal — YouTube is rebuilding the cache from scratch. After the first video or two, everything should return to normal speed. If YouTube continues to run slowly or crash after clearing cache, the problem may be something else, like a poor internet connection or an outdated app version.

Check that your YouTube app is up to date by opening your phone's app store and searching for YouTube. If an Update button appears, tap it. If you are on a computer, make sure your browser is current by checking its settings or help menu. Restarting your device can also help if clearing cache alone does not solve the problem.

When to clear cache versus when to clear data

Clearing cache is safe and removes only temporary files. Clearing data is a stronger action that removes your login information, settings, and watch history from your device — though your history will still exist on Google's servers if you sign back in. You should only clear data if YouTube is seriously broken and clearing cache did not help.

If you clear data by accident, simply sign back into your Google account in the YouTube app or on the YouTube website. Your subscriptions, playlists, and watch history will reappear within a few minutes because they are stored online, not on your device.

Frequently Asked Questions

Will clearing cache delete my YouTube watch history?

No. Your watch history is stored on Google's servers, not in the cache. Clearing cache only removes temporary files. Your history will still be there when you sign back in. If you want to delete your watch history, you must do that separately through YouTube's settings.

How much space will I free up by clearing cache?

The amount varies depending on how long you have used YouTube without clearing cache. Most users free up between 100 MB and 500 MB. Check your phone's storage settings before and after to see the exact amount on your device.

Do I need to clear YouTube cache regularly?

Not necessarily. Most people only need to clear cache when YouTube starts running slowly or crashing. If YouTube works fine, there is no reason to clear it. Some people clear cache once a month as routine maintenance, but it is not required.

Can I clear cache without uninstalling the YouTube app on iPhone?

No. iOS does not provide a way to clear cache for individual apps without deleting and reinstalling them. This is a limitation of Apple's operating system, not YouTube. Deleting and reinstalling takes about five minutes and is the only option.

What if clearing cache does not fix YouTube problems?

Try restarting your device, checking that your app or browser is up to date, and testing your internet connection. If problems continue, try clearing data instead of just cache, though this will remove your login information and you will need to sign in again.
