If a webpage loads blank, shows outdated content, or your browser freezes mid-scroll, a bloated cache is often the culprit. Every browser stores temporary files — images, scripts, and cookies — to speed up repeat visits, but over time those files pile up and start causing more problems than they prevent.
Clearing browser cache and cookies takes under two minutes and resolves a surprisingly long list of issues: login loops, broken page layouts, videos that won’t play, and general sluggishness. This guide covers Chrome, Firefox, Safari, and Edge on desktop and mobile.
Quick Answer
Press Ctrl+Shift+Delete (Windows) or Cmd+Shift+Delete (Mac) in Chrome, Firefox, or Edge to open the clear-data dialog. Choose All time, check Cached images and files plus Cookies, then click Clear data. In Safari on Mac, go to Safari > Clear History > All History. On iPhone, go to Settings > Safari > Clear History and Website Data.
What Cache and Cookies Actually Do
Your browser uses cache to store copies of pages you’ve visited so the next load is faster. Cookies are small text files websites use to remember your login session, shopping cart, or preferences.
Both are helpful until they aren’t. A cached version of a page can be weeks old. An expired or corrupted cookie can lock you out of a site entirely. Clearing both forces your browser to start fresh with current data from the server.
Pro tip: You don’t need a weekly cleaning schedule. Clear cache when a site behaves oddly, shows content that looks outdated, or after a major site redesign.
Clear Cache and Cookies in Google Chrome
- Open Chrome and press Ctrl+Shift+Delete (Windows) or Cmd+Shift+Delete (Mac).
- Set the time range to All time.
- Check Cookies and other site data and Cached images and files. Leave browsing history unchecked if you want to keep it.
- Click Clear data.
Chrome clears the cache in seconds. You’ll need to log back into most sites afterward — that’s expected behavior, not an error.
On Android: Tap the three-dot menu > Settings > Privacy and security > Clear browsing data, then follow the same steps above.
Clear Cache and Cookies in Mozilla Firefox
- Click the hamburger menu (☰) > Settings > Privacy & Security.
- Scroll to Cookies and Site Data and click Clear Data.
- Check both Cookies and Site Data and Cached Web Content.
- Click Clear.
You can also press Ctrl+Shift+Delete for a quicker dialog with a time-range selector. Mozilla’s official Firefox cache guide has additional screenshots if needed.
Troubleshooting tip: If Firefox still misbehaves after clearing cache, go to Help > More troubleshooting information > Refresh Firefox. It resets settings without deleting bookmarks or passwords.
Clear Cache and Cookies in Safari (Mac and iPhone)
- On Mac, open Safari and click Safari in the menu bar > Clear History.
- Set the range to All History and click Clear History.
Safari clears history and cookies in one step. For cache only — without wiping history — enable the Develop menu under Safari > Settings > Advanced > Show Develop menu, then click Develop > Empty Caches.
On iPhone: Go to Settings > Safari > Clear History and Website Data. If Safari still won’t load pages after clearing, see our guide to Safari not loading on iPhone for deeper fixes.
Clear Cache and Cookies in Microsoft Edge
- Press Ctrl+Shift+Delete or go to Settings > Privacy, search, and services > Choose what to clear.
- Set the time range to All time.
- Check Cookies and other site data and Cached images and files.
- Click Clear now.
Edge is built on Chromium, so the process is nearly identical to Chrome and the same keyboard shortcut works on both.
Browser Comparison at a Glance
| Browser | Keyboard Shortcut | Clears Cookies Separately | Mobile Clear Path |
|---|---|---|---|
| Chrome | Ctrl+Shift+Delete / Cmd+Shift+Delete | Yes | Menu > Settings > Privacy > Clear browsing data |
| Firefox | Ctrl+Shift+Delete / Cmd+Shift+Delete | Yes | Menu > Settings > Data Management |
| Safari | No shortcut (use Develop menu for cache only) | Via Develop > Empty Caches | Settings > Safari > Clear History |
| Edge | Ctrl+Shift+Delete / Cmd+Shift+Delete | Yes | Menu > Settings > Privacy > Clear browsing data |
Common Mistakes to Avoid
- Choosing a short time range. Selecting “Last hour” or “Last 7 days” won’t remove a file cached weeks ago. Always pick All time when troubleshooting a stubborn problem. Fix: change the time range before clicking Clear.
- Clearing cache but skipping cookies. Login loops are caused by corrupted or expired cookies, not cached page files. Fix: always check both boxes together.
- Expecting a dramatic speed boost. Clearing cache helps with stale data and glitchy pages, not sluggish RAM. If your browser is genuinely slow, extensions and memory are the real culprits — see our breakdown of Chrome’s memory usage for steps that apply to most Chromium browsers. Fix: audit your extensions and enable Memory Saver.
- Not restarting the browser afterward. Some cached data doesn’t fully flush until all browser windows close. Fix: quit the browser completely and reopen it.
- Using a third-party “cache cleaner.” Every major browser has built-in tools — no extra app is needed. Fix: use the native dialog described above; skip any app that promises to “speed up your browser.”
Frequently Asked Questions
Will clearing cache delete my saved passwords?
No. Passwords are stored in the browser’s built-in password manager, which is separate from cache and cookies. Clearing browsing data won’t affect them.
How often should I clear my browser cache?
Most users don’t need a fixed schedule. Clear it when a site looks broken, shows outdated information, or after a major redesign of a site you use every day.
Why do I get logged out after clearing cookies?
Cookies store your active login session. Once deleted, the website no longer recognizes you — logging back in creates a fresh cookie and restores access.
Does clearing cache speed up my browser?
It can, if slowness is caused by an oversized or corrupted cache. For persistent sluggishness, managing extensions and RAM use is a bigger lever — our Chrome memory guide covers the steps.
Can I clear cache in Chrome and Firefox on iPhone?
Yes. In Chrome for iOS, tap the three-dot menu > Clear Browsing Data. In Firefox for iOS, tap the menu > Settings > Data Management > Clear Private Data.
Does “Clear History” in Safari also delete cookies?
Yes — Safari’s Clear History removes browsing history, cookies, and cached data in one go. To clear only the cache, use Develop > Empty Caches instead.
Conclusion
Clearing browser cache and cookies is the fastest first step when any site breaks — it costs nothing and takes under two minutes on any device. Use Ctrl+Shift+Delete on Chrome, Firefox, or Edge; work through the Safari menu on Mac or iPhone; and always clear cookies alongside cache to fix login problems, not just stale pages.
