If Safari on your iPhone is suddenly running slowly, displaying outdated information on your favorite websites, or refusing to load pages altogether, the solution is usually right under your nose. Your browser has collected too much “junk” data.
Every time you visit a website, Safari saves tiny files (cache) and tracking tokens (cookies) to make the page load faster next time. Over months of browsing, these files can become corrupted. Here is how to clear Safari cache and cookies on iPhone to get your browser running smoothly again.
The “Nuke” Option: Clear Everything at Once
If you are experiencing severe browsing issues or just want a completely fresh start for privacy reasons, Apple provides a single button to wipe all browsing data simultaneously.
Warning: This will log you out of all websites you are currently signed into, and it will clear your browsing history.
- Open the Settings app on your iPhone.
- Scroll down the long list of apps and tap on Safari.
- Scroll down to the blue text that says Clear History and Website Data and tap it.
- A menu will pop up asking for a timeframe. Choose All history.
- Ensure the Close All Tabs toggle is turned on (this prevents old tabs from immediately reloading the corrupted data).
- Tap the red Clear History button to confirm.
The “Surgical” Option: Clear Data for Specific Websites
What if Safari works perfectly fine, but one specific website (like your bank or a news site) is glitching? You do not need to log yourself out of everything just to fix one site.
You can surgically delete the cookies and cache for a single problematic URL.
- Open the Settings app and tap Safari.
- Scroll to the very bottom of the Safari menu and tap Advanced.
- Tap Website Data at the top of the screen. (Wait a few seconds for the list to populate; it may contain hundreds of sites).
- You can either scroll through the list or use the Search bar at the top to find the broken website.
- Once you find it, swipe left on the website’s name.
- Tap the red Delete button that appears.
Now, go back to the Safari app and reload that specific webpage. It will pull fresh, clean data from the server, which almost always resolves formatting glitches and login errors.
How to Block Cookies Permanently
If you are tired of websites tracking your behavior to serve you targeted ads, you can tell Safari to reject all future cookies. However, be aware that many websites (especially online stores) require cookies to keep items in your shopping cart.
To do this, go to Settings > Safari > Advanced, and toggle the switch for Block All Cookies to the “On” position. If you find that too many websites break, you can always return to this menu and turn it back off.
