What clearing your iPad cache does

Your iPad stores temporary files called cache whenever you use apps and browse the web. These files help apps load faster the next time you open them. Over time, cache builds up and takes storage space — sometimes gigabytes of it — without giving you anything you need to keep. Clearing cache removes these temporary files and frees that space without deleting your photos, documents, or app data.

Cache is different from app data. When you clear cache, your apps still work normally and remember your passwords and settings. You are only removing the temporary copies of images, web pages, and other files that apps downloaded to speed things up. Think of it like clearing out a junk drawer — you keep the important things, but throw away the stuff you do not need anymore.

Key Takeaways

  • Clearing Safari cache removes temporary web files but keeps your bookmarks, history, and saved passwords intact.
  • Most apps do not have a built-in cache-clearing option, so you delete and reinstall them to clear their cache completely.
  • Offloading an app removes it temporarily while keeping your data, and reinstalling it clears cache without losing anything.
  • Clearing cache typically frees between 500 MB and several gigabytes, depending on how long since you last cleared it.
  • You can also clear cache by going to Settings and selecting individual apps to offload, which is faster than deleting them.

Clear Safari cache through Settings

Safari is the easiest app to clear cache from because it has a built-in option. Open Settings on your iPad, scroll down and tap Safari, then scroll to the bottom of that screen. You will see a section called "Clear History and Website Data." Tap it, and a popup will ask you to confirm — tap "Clear History and Data" again.

This removes temporary files from websites you visited, but keeps your bookmarks, saved passwords, and autofill information. If you want to keep your browsing history but still clear cache, you have a second option: go back to Settings > Safari and turn off "Privacy Preserving Ad Measurement" and "Privacy Preserving Ad Attribution," then turn them back on. This is slower and less complete, so the first method is usually better.

Offload apps to clear their cache without losing data

Most apps store cache that you cannot clear directly from within the app. The fastest way to clear it without deleting the app is to offload it. Offloading removes the app temporarily but keeps all your data — your saved games, login information, documents, everything. When you reinstall it, the app works exactly as before, but the cache is gone.

Go to Settings, tap General, then tap iPad Storage. Scroll through the list until you find the app you want to clear cache from, tap it, and select "Offload App." A popup will warn you that the app will be removed but your data will be kept — tap "Offload" to confirm. The app icon will stay on your home screen but appear faded. Tap it again to reinstall the app, which takes a few seconds to a few minutes depending on the app size and your internet speed.

Delete and reinstall apps for a complete cache clear

If you want to completely remove an app and start fresh, you can delete it and reinstall it from the App Store. This clears cache and all app data, so use this only if you do not mind losing saved games, documents, or login information. For most apps, offloading is the better choice because it keeps your data.

To delete an app, press and hold its icon on your home screen, tap "Remove App," then tap "Delete App" and confirm. Go to the App Store, search for the app by name, and tap the cloud icon with a down arrow to reinstall it. Your iPad will read the app fresh, with no cache from before.

Check your iPad storage to see how much cache you have

Before you start clearing cache, you can see roughly how much storage each app is using. Go to Settings, tap General, then tap iPad Storage. The list shows each app with a size number next to it. Apps with large sizes often have large caches — Mail, Photos, Safari, and streaming apps like Netflix or YouTube typically use the most space.

The number shown is the total size of the app plus its cache and data combined, so you cannot see exactly how much is cache versus data. But if an app shows 2 GB and you know you only have a few photos in it, most of that is probably cache. Offloading that app will free most of that space.

Clear cache from Mail and Photos apps

Mail and Photos both build large caches over time. For Mail, go to Settings, scroll down and tap Mail, then tap Accounts. Tap the account you want to clear cache from, then tap the account name again. Scroll down and tap "Advanced," then tap "Mailbox Behavior." You cannot clear cache directly here, but offloading the Mail app (using the method in the earlier section) will clear its cache completely.

For Photos, the cache is harder to separate from your actual library. If you have synced photos from iCloud, you can go to Settings > [Your Name] > iCloud > Photos and turn off "iCloud Photos," wait a few minutes, then turn it back on. This forces your iPad to re-read the photo library fresh. Do this only if you have a strong internet connection, because it can take a long time.

Restart your iPad after clearing cache

After you clear cache or offload apps, restart your iPad to make sure the changes take effect and to free up any remaining temporary files. Press and hold the top button and either volume button until the power-off slider appears, then drag it to turn off your iPad. Wait 10 seconds, then press and hold the top button again until the Apple logo appears.

Restarting is not always necessary, but it helps your iPad run more smoothly after you have cleared a lot of cache. If you notice your iPad is slower or apps are crashing, a restart often fixes it.

Frequently Asked Questions

Will clearing cache delete my photos or documents?

No. Cache is temporary files only. Your photos, documents, emails, and app data stay on your iPad. Clearing cache removes things like thumbnail previews, temporary web pages, and downloaded images that apps use to speed up loading — not the files you created or saved.

How often should I clear my iPad cache?

There is no set schedule. Clear cache when your iPad storage is running low, when apps are running slowly, or when you notice an app is taking up more space than it should. Many people clear cache once every few months, but it depends on how much you use your iPad and which apps you use most.

What is the difference between clearing cache and clearing data?

Cache is temporary files apps read to speed up loading. Data is information you created or saved — passwords, settings, documents, game progress. Clearing cache removes temporary files only. Clearing data removes everything, including your settings and saved information. Offloading an app clears cache but keeps data.

Can I clear cache from all apps at once?

Not directly. You have to offload or delete apps one at a time. The fastest way to clear cache from multiple apps is to go to Settings > General > iPad Storage, then offload the apps using the most space. Start with the largest ones, like Mail, Safari, or streaming apps.

Will my apps work slower after I clear cache?

No. Apps may take a few extra seconds to load the first time after you clear cache, because they have to read temporary files again. After that first load, they work normally. The temporary slowdown is worth the storage space you free up.
