What clearing cache means and why you might do it

Cache is temporary data that apps and your web browser store on your iPad to load faster next time. When you visit a website, your browser saves images, text, and code. When you use an app, it stores login information, settings, and pieces of content you've already seen. This speeds things up — but over time, cached data can take up storage space, cause an app to behave oddly, or slow your iPad down.

Clearing cache won't delete your passwords, photos, or documents. It only removes those temporary files. You might clear cache if an app keeps crashing, a website looks broken, you're running low on storage space, or you want to free up memory before a demanding task.

The steps differ depending on whether you're clearing cache from Safari (Apple's browser), a third-party browser like Chrome or Firefox, or individual apps. Each method takes less than five minutes.

Key Takeaways

  • Cache is temporary data apps and browsers store to load faster, and clearing it won't delete your passwords or photos.
  • Safari cache clears through Settings > Safari > Clear History and Website Data, where you choose the time range.
  • Chrome, Firefox, and other browsers have their own cache-clearing menus inside the app itself, not in iPad Settings.
  • Individual apps sometimes let you clear their cache in their own settings, though many apps only clear cache when you uninstall and reinstall them.
  • If an app is crashing or freezing, clearing its cache is often faster than deleting and reinstalling it.

Clearing Safari cache through iPad Settings

Safari is the default browser on iPad. To clear its cache, open the Settings app on your home screen, then scroll down and tap Safari. Near the bottom of the Safari settings page, you'll see Clear History and Website Data. Tap it.

A popup will ask you to choose a time range. Your options are the last hour, today, today and yesterday, or all time. If you want to clear everything Safari has stored, choose all time. Tap Clear History and Website Data again to confirm. Safari will log you out of most websites, so you'll need to sign back in the next time you visit them.

This method clears both your browsing history and cached website data at the same time. If you only want to clear cache and keep your history, you'll need to use Safari's menu instead: open Safari, tap the Tabs button (the overlapping squares icon at the bottom right), then tap History at the bottom, then tap Clear in the bottom right corner. Choose your time range and confirm.

Clearing cache in Chrome, Firefox, and other browsers

If you use Chrome, Firefox, Edge, or another browser on your iPad, the cache-clearing menu is inside the app itself, not in iPad Settings. Open the browser you want to clear, then look for the menu button — usually three horizontal lines or three dots in the top right or bottom right corner.

In Chrome, tap the three dots, scroll down and tap Settings, then tap Privacy, then Clear Browsing Data. Choose your time range and make sure Cached Images and Files is checked. Tap Clear Browsing Data to finish.

In Firefox, tap the menu button (three horizontal lines), scroll down to Settings, tap Privacy, then scroll to Clear Private Data and tap it. Check Cache and tap Clear Private Data.

In Edge, tap the three dots, tap Settings, tap Privacy, then Clear Browsing Data. Choose your time range and tap Clear Now.

Clearing cache for individual apps

Some apps let you clear their cache from within the app's own settings. Open the app, look for a Settings or Preferences menu (often a gear icon), and search for options like Clear Cache, Storage, or Data. Not all apps offer this option — it depends on how the app was built.

If an app doesn't have a built-in cache-clearing option, you can force-clear its cache by uninstalling and reinstalling it. Press and hold the app icon on your home screen, tap Remove App, then Delete App. Go to the App Store, search for the app, and tap Get to reinstall it. This removes all cached data but keeps your account logged in if you've signed in through the app.

Before you uninstall an app, make sure you know your login details. Some apps don't sync passwords across devices, so you may need your username and password to sign back in after reinstalling.

When to clear cache versus when to restart your iPad

If an app is crashing or a website won't load properly, clearing cache is the first thing to try. It's faster than restarting and solves most problems caused by corrupted temporary files.

If clearing cache doesn't fix the problem, restart your iPad. Press and hold the Top button and either Volume Up or Volume Down (depending on your model) until the power-off slider appears. Drag the slider to turn off your iPad, wait 10 seconds, then press and hold the Top button again until the Apple logo appears. A full restart clears memory and resets running processes in ways that clearing cache alone cannot.

How much storage space clearing cache actually frees

The amount of storage you'll free depends on how long you've been using your iPad and which apps you use most. Clearing Safari cache might free anywhere from 100 megabytes to several gigabytes. Clearing cache for a streaming app like Netflix or YouTube could free 500 megabytes to 2 gigabytes. The only way to know for certain is to check your iPad's storage before and after.

To see how much storage each app is using, go to Settings > General > iPad Storage. This list shows the total size of each app, including its cache. After you clear cache, the number next to that app should decrease. If you're running very low on storage and clearing cache doesn't free enough space, deleting apps you don't use regularly or offloading photos to iCloud will have a bigger impact.

Frequently Asked Questions

Will clearing cache delete my passwords?

No. Clearing cache removes only temporary files like images and website code. Saved passwords, autofill information, and login credentials stay on your iPad. You may need to sign back into websites after clearing Safari cache, but that's because the browser forgets which sites you were logged into — your actual password is still saved.

Can I clear cache automatically on a schedule?

Safari doesn't have a built-in automatic cache-clearing schedule on iPad. Some third-party browsers like Firefox offer an option to clear cache every time you close the app — check the browser's settings to see if this feature is available. Otherwise, you'll need to clear cache manually when you notice performance issues or storage is running low.

What's the difference between clearing cache and clearing browsing history?

Browsing history is the list of websites you've visited. Cache is the temporary files those websites stored on your iPad. Clearing history removes the list but leaves the cached files behind. Clearing cache removes the files but doesn't necessarily remove the history. In Safari Settings, the option clears both at once, but in the Safari app menu, you can clear history without touching cache.

Why does an app keep asking me to log in after I clear cache?

Some apps store login tokens in their cache — temporary files that keep you signed in without entering your password every time. Clearing cache removes those tokens, so the app forgets you were logged in. This is normal and not a problem. Just sign back in. If an app keeps logging you out even when you haven't cleared cache, that's a sign the app itself has a bug or your account has a security issue.

Is it safe to clear cache regularly?

Yes. Clearing cache regularly won't harm your iPad or your data. The only minor inconvenience is that websites and apps will load slightly slower the first time you use them after clearing, because they have to download their files again. After that, performance returns to normal as new cache builds up.
