How to Clear Cache on iPhone

Clear cache on iPhone by removing Safari history and website data, deleting website data only, checking app storage, and offloading apps only when needed.

An iPhone-like device sits on a light gray desk, displaying a generic home screen with various rounded app icons. A soft blue focus ring highlights the gear-shaped Settings icon, which has 'Settings' labeled below it. A blurred notebook and a small plant are in the background.
To begin clearing cache, tap the Settings app on your iPhone-like device's home screen.
Quick answer:

To clear cache on iPhone, open Settings, go to Apps, choose Safari, then tap Clear History and Website Data. To keep Safari history, use Advanced в†’ Website Data в†’ Remove All Website Data instead. For other apps, check the app settings or use iPhone Storage.

Before you start

Clearing cache can make Safari or an app load fresh data again, but it is not the same as resetting your iPhone. It mainly removes temporary website files, cookies, browsing history, or app-specific stored data.

Important:

Clearing Safari history and website data can sign you out of websites and remove saved site preferences. Read the confirmation screen before you continue.

Step-by-step guide

  1. Open iPhone Settings

    Unlock your iPhone and open the Settings app. On newer iOS versions, Apple places Safari under Apps, so do not worry if Safari is not visible immediately on the first Settings screen.

    Open the iPhone Settings app before clearing cache
    Start in the Settings app, where Safari and app storage options are managed.
  2. Open Safari settings

    Scroll to Apps, tap it, then select Safari. If your iPhone uses an older Settings layout, you may see Safari directly in the main Settings list.

    Open Safari settings to clear browsing history, cookies and cached website data.
  3. Clear Safari history and website data

    Tap Clear History and Website Data. Choose the available time range if iOS shows one, then confirm. This is the simplest way to remove Safari cache together with history and cookies.

    This removes Safari history, cookies and cached website data from the selected time range.
  4. Remove website data only if you want to keep history

    To keep browsing history, go to Safari в†’ Advanced в†’ Website Data, then choose Remove All Website Data. If the button is greyed out, there may be no data to remove or Screen Time restrictions may be active.

    Use Website Data when you want to clear cookies and cache without clearing browsing history.
  5. Check app storage for non-Safari apps

    For apps like social networks, messengers or browsers, open the app’s own settings and look for cache, storage or downloads. You can also check Settings → General → iPhone Storage. Use Offload App only when you understand what will stay and what will be removed.

Tip:

If one website behaves strangely, try clearing only that websiteРІР‚в„ўs data first. It is less disruptive than clearing all Safari history and cookies.

FAQ

Does clearing cache delete my photos or contacts?

No. Clearing Safari history, cookies and website data does not delete photos, contacts, messages or installed apps.

Will I be signed out of websites?

Yes, it can happen. Removing cookies and website data may sign you out of websites and remove saved site preferences.

Can I clear cache for every iPhone app at once?

Not usually. iOS does not offer one universal cache button for all apps. Use each app's settings, delete and reinstall the app, or offload apps when appropriate.

What if the clear button is greyed out?

Apple notes that this can happen when there is no website data to clear or when Screen Time web content restrictions are active.
