What clearing Facebook cache does
Clearing your Facebook cache removes temporary files that Facebook stores on your device — things like images you've already viewed, login information, and parts of pages you've visited. This frees up storage space and can sometimes fix problems like the app freezing, loading slowly, or showing outdated information.
Cache is not the same as your actual Facebook data. Clearing it will not delete your messages, photos, posts, or account information. The next time you open Facebook, it will download those files again, so the app will work normally.
How much space you free up depends on how long you've been using Facebook without clearing the cache. Some people recover a few hundred megabytes; others recover several gigabytes if they haven't cleared it in years.
Key Takeaways
- Clearing Facebook cache removes temporary files stored on your device but does not delete your messages, photos, or account data.
- The steps are different depending on whether you use the Facebook app, a web browser, or a computer — each has its own cache location.
- On iPhone, you clear cache through the Settings app under Facebook; on Android, you use the Apps settings; on a computer, you clear your browser cache.
- If Facebook is running slowly or crashing, clearing the cache often fixes the problem without losing any of your actual account information.
Clear Facebook cache on iPhone
On iPhone, Facebook cache lives in your device settings, not in the app itself. Open Settings, scroll down and tap Facebook, then tap Clear Cache. That's the entire process — you don't need to open the Facebook app at all.
If you don't see a Facebook option in Settings, it means Facebook is not installed or you haven't used it yet. If you see Facebook but no "Clear Cache" option, your iPhone version may be older. In that case, you can uninstall and reinstall the Facebook app instead, which clears all its temporary files.
After clearing cache, open Facebook normally. The app will take a few extra seconds to load the first time as it rebuilds the cache, but it should run faster afterward.
Clear Facebook cache on Android
On Android, open Settings, then go to Apps (sometimes called Application Manager. Find and tap Facebook, then tap Storage, and finally tap Clear Cache. Do not tap "Clear Data" — that removes more than cache and can sign you out of the app.
If you can't find the Facebook app in your Apps list, swipe left or right to find the correct tab — some Android phones separate system apps from downloaded apps. Once you find Facebook, the Storage menu should appear immediately after you tap it.
Some Android phones use slightly different menu names. If you see Storage and Cache as a single option, tap that and then select Clear Cache from the next screen.
Clear Facebook cache in your web browser
If you use Facebook in a web browser rather than the app, you clear cache through the browser itself, not through Facebook. The steps depend on which browser you use.
In Chrome: Click the three-dot menu in the top right, select Settings, click Privacy and security, then Clear browsing data. Make sure Cached images and files is checked, set the time range to All time, and click Clear data.
In Safari: Click Safari in the top menu, select Settings, go to the Privacy tab, and click Manage Website Data. Search for "facebook" in the list, select it, and click Remove.
In Firefox: Click the three-line menu in the top right, select Settings, go to Privacy & Security, scroll to Cookies and Site Data, and click Clear Data. Check Cached Web Content and click Clear.
Clear Facebook cache on Windows or Mac
If you use the Facebook app on a Windows computer or Mac, the steps are similar to mobile. On Windows 10 or 11, open Settings, click Apps, find Facebook in the list, click it, then click Storage and Clear cache.
On Mac, open System Settings, click General, then Storage, find Facebook in the list, and click it. You may see an option to offload or delete the app — offloading removes the app but keeps your data, while deleting removes everything. To clear only cache without removing the app, reinstall it instead.
Most people use Facebook in a web browser on their computer rather than the app. If that's you, follow the browser steps in the previous section instead.
What to do if clearing cache doesn't fix the problem
If Facebook is still slow or crashing after you clear the cache, try closing the app completely and reopening it. On iPhone, swipe up from the bottom of the screen to open the app switcher, find Facebook, and swipe it away. On Android, open your recent apps and swipe Facebook away. On a computer, close the browser tab or app window completely and reopen it.
If the problem continues, try uninstalling and reinstalling the Facebook app. This removes all temporary files and resets the app to its original state. You won't lose your account or messages — they're stored on Facebook's servers, not on your device.
If Facebook works fine in a web browser but crashes in the app, the problem is likely with the app itself rather than your cache. In that case, reinstalling the app is usually faster than troubleshooting further.
Frequently Asked Questions
Will clearing cache delete my messages or photos?
No. Cache is only temporary files that help the app load faster. Your actual messages, photos, posts, and account information are stored on Facebook's servers and are not affected by clearing cache.
How often should I clear Facebook cache?
There's no set schedule. Clear it when your phone is running low on storage, when Facebook is running slowly, or if the app is crashing. Some people do it once a year; others do it every few months depending on how much they use Facebook.
What's the difference between clearing cache and clearing data?
Clearing cache removes temporary files only. Clearing data removes cache plus your login information, preferences, and downloaded content — it will sign you out of the app. Only clear data if you're having serious problems or planning to uninstall the app.
Does clearing cache make Facebook load faster?
Sometimes. If your cache has grown very large or contains corrupted files, clearing it can speed things up. However, the first time you use Facebook after clearing cache, it may load slightly slower as it rebuilds the temporary files.
Can I clear cache for just Facebook, or does it clear cache for all apps?
On phones, you can clear cache for just Facebook through the Settings app. In web browsers, clearing cache removes temporary files from all websites you've visited, not just Facebook. If you want to clear only Facebook's cache in a browser, you can clear cookies and site data for just that domain.
