How to Clear Cache on iPhone (iOS)

Remove cached data to fix loading errors and reclaim disk space.

Last verified: February 21, 2026

iOS doesn't give users direct access to app cache folders the way desktop OSes do — instead, you clear cache either through the individual app's own settings or by offloading and reinstalling the app entirely. Safari is the exception: Settings > Safari > Clear History and Website Data removes both browsing history and the full website cache in one step. For other apps, Settings > General > iPhone Storage lists each app's Document & Data size, and tapping Offload App removes the cache and app binary while preserving your personal data and account.

Quick Steps

Follow in order for the fastest result.

  1. 1For Safari: Settings > Safari > Clear History and Website Data. For other apps: Settings > General > iPhone Storage > [App] > Offload App.
  2. 2Restart the app or browser after clearing.
  3. 3For system-level cache on Windows, search Disk Cleanup from Start, check Temporary files, and run cleanup.

Frequently Asked Questions

What does clearing cache do on iPhone (iOS)?
Clearing cache removes temporary files that apps and browsers store locally to load faster. This can fix loading errors, blank pages, login issues, and outdated content. It does not delete your personal data, passwords, or files — only performance-related temporary data.
Will clearing cache on iPhone (iOS) delete my passwords or data?
Clearing cache only removes temporary files. Your saved passwords are stored separately and are not affected. If you also clear Cookies or Storage/Data (a separate option), you will be logged out of websites and apps, but no personal files are deleted.
How often should I clear my cache on iPhone (iOS)?
There is no set schedule — clear cache when you notice specific problems: pages not loading correctly, apps showing outdated content, or login loops. Clearing cache too frequently provides no benefit, as it forces everything to reload from scratch each time.
Does clearing cache on iPhone (iOS) speed up the device?
It can provide a brief improvement if the cache has become corrupt or very large, but in normal use, cache exists to speed things up. Clearing it makes the first load of each app or website slower while it rebuilds. For general device speed, focus on freeing up storage and disabling unused startup programs instead.
