What clearing cache does and why you might want to

Cache is temporary data your tablet stores to make apps and websites load faster the next time you use them. Over time, this cache builds up and can slow your tablet down, use storage space, or cause an app to behave oddly. Clearing it is safe—you won't lose photos, messages, or files—but websites and apps will take a moment longer to load the first time after you clear it.

Most people clear cache when an app is freezing, when storage is running low, or as routine maintenance. The process takes a few minutes and works the same way whether you use an iPad, Samsung tablet, or Android device.

Key Takeaways

  • Cache is temporary data apps and websites store to load faster; clearing it frees storage but won't delete your photos, messages, or files.
  • On iPad, go to Settings > General > iPad Storage, tap an app, and select Offload App or delete and reinstall it to clear its cache.
  • On Android tablets, go to Settings > Apps, select an app, tap Storage, and choose Clear Cache (or Clear Data for a deeper clean).
  • Clearing your browser cache works differently: in Safari or Chrome, find the history or privacy settings and select the time range you want to clear.
  • If an app still misbehaves after clearing cache, restarting your tablet or reinstalling the app usually solves the problem.

Clearing cache on an iPad

On iPad, the easiest way to clear an app's cache is through Settings. Open Settings, tap General, then tap iPad Storage. Scroll through the list and find the app you want to clear. Tap it, and you'll see two options: Offload App and Delete App.

Tap Offload App. This removes the app but keeps your data—photos, messages, saved games—intact. Your home screen will show the app icon grayed out. When you tap it again, iPad will reinstall it automatically, and the cache will be gone. If you want a complete fresh start, tap Delete App instead, then reinstall it from the App Store.

To clear cache for all apps at once, go to Settings > General > iPad Storage and look at the list. Apps using the most storage appear at the top. You can offload multiple apps this way, though it takes longer than clearing one at a time.

Clearing cache on an Android tablet

On Android tablets, open Settings and look for Apps or process Manager (the exact name varies by manufacturer—Samsung calls it Apps, while others may say process Manager). Tap it, then find the app whose cache you want to clear.

Tap the app name, then tap Storage. You'll see two buttons: Clear Cache and Clear Data. Tap Clear Cache to remove temporary files without losing your saved data, login information, or settings. If the app is still misbehaving, tap Clear Data instead—this removes everything, so you'll need to log back in and reset preferences.

To clear cache for multiple apps, repeat this process for each one. Some Android tablets also have a built-in storage cleaner in Settings > Storage or Settings > Device Care that can clear cache for all apps at once, though this varies by manufacturer.

Clearing your browser cache on Safari or Chrome

Browser cache works differently from app cache. On iPad using Safari, open Settings, scroll down and tap Safari, then tap Clear History and Website Data. Choose the time range—Last Hour, Today, Last Day, Last Week, Last Month, or All Time—and tap Clear History and Data. This removes cached web pages, cookies, and browsing history.

On Android tablets using Chrome, open the Chrome app, tap the three-dot menu in the top right, and select Settings. Tap Privacy and Security, then Clear Browsing Data. Choose the time range from the dropdown at the top, make sure Cached Images and Files is checked, and tap Clear Data.

If you use Firefox or another browser, the steps are similar: look for Settings or Privacy, find the option to clear cache or browsing data, and select the time range you want to clear.

When to clear cache versus when to restart your tablet

If only one app is slow or freezing, clearing that app's cache is the right move. If your whole tablet feels sluggish, restart it first—hold the power button, slide to power off, wait 10 seconds, then turn it back on. A restart clears temporary memory and often fixes slowness without deleting anything.

If restarting doesn't help and storage is low, clearing cache is your next step. Check your tablet's storage first: on iPad, go to Settings > General > iPad Storage; on Android, go to Settings > Storage. If you're using more than 80 percent of available space, clearing cache and offloading unused apps will help.

What to do if clearing cache doesn't fix the problem

If an app still crashes or freezes after you clear its cache, try offloading or uninstalling it and reinstalling it fresh from the App Store or Google Play. This is more thorough than clearing cache alone and fixes most app problems.

If your whole tablet is slow even after clearing cache and restarting, the issue may be a full storage drive, too many background apps, or an outdated operating system. Check for system updates: on iPad, go to Settings > General > Software Update; on Android, go to Settings > About Device > Software Update. Install any available updates and restart.

If problems continue, contact the app's support team or the tablet manufacturer. Persistent slowness can sometimes indicate a hardware issue that clearing cache won't solve.

Frequently Asked Questions

Will clearing cache delete my photos or messages?

No. Cache is only temporary data apps use to load faster. Your photos, messages, files, and login information stay on your tablet. The only exception is if you choose Clear Data instead of Clear Cache on Android, which removes everything for that app—but you'll still have your photos and messages in other apps.

How often should I clear my tablet's cache?

There's no set schedule. Clear cache when an app misbehaves, when storage is running low, or every few months as maintenance. Most people don't need to clear it more often than that unless they use their tablet heavily.

Can I clear cache for all apps at once?

On iPad, you can offload multiple apps from Settings > General > iPad Storage, but you do them one at a time. On Android, some tablets have a storage cleaner in Settings that clears all app cache at once, though this varies by manufacturer. Otherwise, you'll clear them individually.

Why is my tablet still slow after clearing cache?

Cache is usually not the main cause of slowness. Restart your tablet first, then check if storage is nearly full—if it is, delete unused apps or files. If slowness continues, check for system updates or contact the manufacturer, as the issue may be something else.

Is it safe to clear cache?

Yes, it's completely safe. Cache is meant to be temporary and can be rebuilt. The only minor inconvenience is that apps and websites will load slightly slower the first time you use them after clearing cache.
