Clearing Safari Cache on iPhone and iPad: Detailed Guide

Introduction / Why This Is Needed

Safari's cache (cache memory) is a storage for temporary files (images, CSS styles, scripts) that the browser downloads from websites to render them faster on subsequent visits. Over time, this cache can:

• Take up space on your device (sometimes hundreds of megabytes).
• Become outdated, leading to incorrect website display (broken styles, new elements not loading).
• Cause authorization errors if a site's security system updates but old cookies remain in the cache.
• Slow down Safari due to conflicts between outdated and new resources.

Clearing the cache is a safe and quick procedure that often solves most problems related to "broken" webpage displays on iPhone or iPad.

Requirements / Preparation

Before you begin, ensure:

1. You have a device running iOS 16.0 or later (the interface may differ slightly on older versions).
2. You have access to the device (not locked by password/biometrics).
3. You are prepared for frequently visited sites to load slightly slower the first time after the procedure (the browser will need to re-download all resources).

Step-by-Step Guide

Step 1: Open the 'Settings' App

Find the 'Settings' icon (gray gear) on your home screen and tap it.

Step 2: Go to the Safari Section

In the long list of settings, scroll down and select 'Safari'.

Step 3: Clear History and Website Data (Primary Method)

This is the simplest and most comprehensive method. It removes everything: browsing history, cookies (authorization files), and web cache.

1. In the Safari section, find the 'Privacy & Security' block.
2. Tap the 'Clear History and Website Data' option.
3. A warning will appear stating you will be logged out of all accounts. Tap 'Clear History and Data' to confirm.

⚠️ Important: After this, you will be automatically logged out of all websites (Google, social networks, banks, etc.). Be prepared to re-enter your login and password.

Step 4: (Alternative) Clear Only the Cache via Advanced Settings

If you need to clear only the cache, preserving history and cookies (e.g., to avoid logging out of accounts), use this method.

1. Return to the main 'Safari' settings page (tap '< Safari' in the top-left corner).
2. Scroll to the very bottom and select 'Advanced'.
3. Enable the 'Web Developer' toggle (if it was off). This grants access to the needed menu item.
4. Return to the main Safari settings page (again, tap '< Safari').
5. Now a new 'Advanced' section will appear at the bottom of the list. Tap it.
6. Select the 'Website Data' option.
7. Tap 'Remove All Website Data' and confirm the action.

This method will delete only the cache and website data, leaving your logins and browsing history untouched.

Verifying the Result

1. Open Safari.
2. Navigate to a site that previously displayed incorrectly (e.g., with "broken" styles).
3. The page should reload with fresh, up-to-date resources. If the issue was cache-related, it will be resolved.
4. To confirm space was freed, go to Settings → General → iPhone Storage. The 'Safari' section will show a reduced data volume.

Potential Issues

• Issue: Websites load very slowly after clearing the cache.
  • Solution: This is normal behavior on the first launch. The browser re-downloads all resources. After a few visits, sites will speed up again thanks to a new, "clean" cache.
• Issue: Cannot find the 'Website Data' option in 'Advanced'.
  • Solution: Ensure you have enabled the 'Web Developer' toggle in Settings → Safari → Advanced. Without this, the menu item will not appear.
• Issue: Error when attempting to clear ('Action Could Not Be Completed').
  • Solution: Try performing a soft restart of the device (quickly press and release the volume up button, then the volume down button, then hold the power button until the power-off slider appears). After turning it back on, repeat the procedure. If the problem persists, check if parental controls are enabled (Settings → Screen Time → Content & Privacy Restrictions).
