How to Clear Cache on iPhone, Android, Windows and Mac

Every time you visit a website, your device stashes copies of images and scripts to make loading faster later — but that cached data can quietly balloon into hundreds of megabytes and cause pages to misbehave. This cross-platform guide covers how to clear cache on iPhone, Android, Windows 10, and Mac, and when it actually makes sense to do it.

Average browser cache size (mobile &desktop): 200–500 MB ·
Storage freed by clearing cache (typical): 100–300 MB per browser ·
Page load speed improvement after clearing cache: 10–30% (Google support) ·
Chrome cache can exceed: 1 GB on heavy-use computers

The table below rounds up the core facts about browser cache and clearing it — drawn from official platform documentation.

How do I clear the cache on my iPhone?

iPhone cache lives mainly inside Safari and individual apps. Unlike Android, there isn’t a one‑tap “clear all cache” button. Here’s how to handle each type.

Clearing Safari cache on iPhone

• Go to Settings > Safari > Clear History and Website Data. This erases cached files along with browsing history and cookies (Apple Support).
• If you use Safari profiles, you can clear history for only one profile or all profiles at once (Apple Support).

Clearing app cache on iPhone

• Apple offers no system‑wide “clear app cache” button. For most apps, the only option is to offload or delete the app (Capterra).
• Offload an app: Settings > General > iPhone Storage > tap the app > Offload App. This removes the app but keeps its documents and data.
• Delete an app: Tap Delete App — this removes the app and all its cached files. Reinstalling will not restore saved data unless it’s synced via iCloud or another service (Capterra).

Using iPhone Storage settings

• Settings > General > iPhone Storage shows a list of apps and their data usage. Tap an app to see options for offloading or deleting.
• For third‑party browsers like Chrome or Firefox, clear their cache from within the browser settings (Trend Micro Help Center).

The implication: iPhone users must accept that system-level cache management doesn’t exist — each app or browser needs individual attention.

How to clear cache on Android?

Android gives you more granular control — you can clear cache per app, per browser, or even wipe the system cache partition.

Clearing cache on Samsung devices

• Open Settings > Device Care > Storage > Clean Now. This removes temporary files including app caches (Android).
• For older Samsung models: Settings > Device maintenance > Storage > Clean.

Clearing cache on Google Chrome for Android

• Open Chrome, tap the three‑dot menu > History > Clear browsing data.
• Choose a time range (e.g., Last hour, All time), check Cached images and files and optionally Cookies and site data, then tap Clear data (Android).

Clearing app cache on Android (general)

• Per‑app cache: Settings > Apps > select the app > Storage > Clear Cache. This removes temporary files but leaves personal data untouched (Android).
• On older Android versions: Settings > Storage > Cached data > OK.
• Advanced: Booting into recovery mode and wiping the cache partition clears system‑level cached data on some devices (Android).

What this means: Android gives you power but also requires you to remember multiple clearing paths — per-app and per-browser — to fully reclaim space.

How do I clear cache on Windows 10?

Windows stores caches at both the browser and system levels. The fastest path is usually inside the browser.

Clear cache in Microsoft Edge

• Click the three‑dot menu > Settings > Privacy, search, and services > Choose what to clear under “Clear browsing data.” Select Cached images and files and click Clear now (Microsoft Support).
• Keyboard shortcut: Ctrl+Shift+Delete opens the clearing dialog directly.

Clear cache in Chrome on Windows

• Three‑dot menu > More tools > Clear browsing data — or use Ctrl+Shift+Delete. Check “Cached images and files” and hit Clear data (Google Chrome Help).

Clear temporary files via Disk Cleanup

• Type Disk Cleanup in the Start menu, select the drive (usually C:), then check Temporary Internet Files and other cache‑related categories before clicking OK.
• Windows 11 follows the same pattern: Settings > System > Storage > Temporary files (Microsoft Support).

The pattern: Windows offers both browser-level and system-level cache removal — using Disk Cleanup catches what browsers sometimes miss.

Is it good to clear your cache?

The short answer is yes — but not all the time. Here’s when it helps and when you might want to hold off.

Benefits of clearing cache

• Frees storage space: Clearing the browser cache can recover 100–300 MB per browser (Google Chrome Help).
• Resolves website loading issues: Outdated cached files can cause layout breaks, missing images, or error messages. A fresh cache load fixes these (Mozilla Support).
• Improves privacy: Clearing cache removes locally stored browsing data that could be accessed by others who use your device (Hexnode).

Potential downsides

• You may be logged out of websites because clearing cache often includes cookies.
• The first visit to a site after clearing will take longer as the browser downloads fresh assets.
• Frequent clearing (daily) offers little benefit and just wastes time — the cache rebuilds almost immediately.

When should you clear cache?

• When a website looks broken or behaves strangely.
• Before selling or handing over your device.
• Every few months just to keep storage tidy.

The catch: There is no universal “right” frequency — your usage patterns and the specific problems you encounter should dictate when you clear.

Where can I find the cache in settings?

Cache lives in different places depending on whether you’re looking at browser settings, OS system storage, or individual app preferences.

Finding cache in browser settings (Chrome, Edge, Firefox)

• Chrome: Menu > More tools > Clear browsing data > check “Cached images and files” (Google Chrome Help).
• Edge: Menu > Settings > Privacy, search, and services > Choose what to clear (Microsoft Support).
• Firefox: Menu > Preferences > Privacy & Security > Cookies and Site Data > Clear Data, then check “Cached Web Content” (Mozilla Support).

Finding cache in system settings (Windows, Mac)

• Windows: Settings > System > Storage > Temporary files — select “Temporary Internet Files” and others (Microsoft Support).
• Mac: Open Finder, press Cmd+Shift+G, type ~/Library/Caches and delete individual app cache folders. No system‑wide button exists (Apple Support).

Finding cache in app settings (Android, iOS)

• Android: Settings > Apps > select app > Storage > Clear Cache (Android).
• iOS: Settings > General > iPhone Storage > tap app > Offload or Delete. No per‑app clear cache button exists natively (Capterra).

The pattern: Browser cache lives in the browser’s privacy settings; system cache lives in the storage settings; app cache is managed per‑app.

Step-by-Step Cache Clearing Guide

These are the fastest paths for each major platform — ideal to bookmark or share with someone troubleshooting a website issue.

1. iPhone (Safari): Settings > Safari > Clear History and Website Data. (Apple Support)
2. Android (Chrome): Chrome menu > History > Clear browsing data > Cached images and files > Clear data. (Android)
3. Windows (any browser): Press Ctrl+Shift+Delete, select “Cached images and files,” click Clear. (Microsoft Support)
4. Mac (Safari): Enable Develop menu (Safari > Preferences > Advanced), then Develop > Empty Caches. (Apple Support)
5. Disk Cleanup (Windows): Start > type “Disk Cleanup” > select drive > check “Temporary Internet Files” > OK.

What this means: The trade-off is clear — you gain storage and fix glitches but pay with one slower page load and possible logouts.

What we know — and what’s still unclear

Based on the available documentation and expert guidance, here’s the evidence sorted into confirmed facts and open questions.

“Clearing your browsing data can help resolve problems with loading websites.”

— Apple Support (official iOS guide)

“You can delete the cache for a specific app or for all apps at once.”

— Android official help

“Clearing your cache will remove the files that are stored on your computer to speed up page loading.”

— Microsoft Support

Cache is a useful tool — but it’s not magic. Knowing when and how to clear it across your devices keeps both storage and browsing experience healthy. For Windows users, deciding when to clear cache means accepting slightly slower initial loads to gain storage and fix display glitches.

For anyone managing multiple devices — a phone, a laptop, a work computer — the takeaway is consistent: cache clearing is a safe, low‑effort maintenance step that can solve a surprising number of everyday browsing hiccups. The trick is knowing exactly where each platform hides the option.
