How to delete Safari website data and free up iPhone storage

Clearing Safari's website data removes the cache, cookies and history the browser has built up, which can free up a few hundred megabytes on your iPhone. It suits anyone whose storage is nearly full or who has a site that keeps loading badly. You need an iPhone running iOS 18 or later, though older versions work the same way.

Steps

  1. Open Settings, tap General, then iPhone Storage. Scroll the app list until you find Safari and tap it to see how much space its website data takes.

  2. Go back to Settings and tap Apps, then Safari on iOS 18 or later. On iOS 17 and earlier the Safari menu sits directly on the main Settings screen.

  3. Tap Clear History and Website Data at the bottom of that screen, then confirm. This removes the cache, cookies and browsing history in one go.

  4. To target a single site, tap Advanced, then Website Data and wait for the list of domains to load.

  5. Swipe left on a site and tap Delete, or tap Edit to remove several at once. Repeat for each site that is holding space.

  6. To wipe everything, tap Remove All Website Data at the bottom of the Website Data screen and confirm.

  7. Force close Safari from the app switcher and open it again, then sign back into any sites you use.

Tips and common mistakes

Clearing cookies signs you out of most websites, so keep a note of any passwords you do not have saved.

Bookmarks, Reading List items and saved tabs are not deleted by clearing website data.

The cache refills as you browse, so clear it again in a few months if storage gets tight.

Questions

Will this delete my bookmarks and history?

Bookmarks and Reading List items stay. Choosing Clear History and Website Data also wipes your browsing history, while deleting single sites under Website Data leaves history alone.

How much space will I actually get back?

It varies. Safari's cache often runs to a few hundred megabytes, and heavy browsing can push it higher, but check the iPhone Storage screen before and after to see the real gain.

Will clearing data fix a website that will not load?

Often yes. A stale cache or corrupted cookie is a common cause of blank pages and login loops, so clear that site's data and reload the page.
