How to Clear Cache on iPhone: Step-by-Step Guide

Learning how to clear cache on iPhone is one of the simplest ways to free up storage space and fix a phone that feels slower than it used to. Cached files — the temporary data your browser and apps save to load things faster — build up quietly over time, and on a phone with limited storage, they can start causing real problems: sluggish apps, websites that refuse to load, and the dreaded “Storage Almost Full” warning.

The good news is that clearing the cache on an iPhone takes just a few minutes, and you do not need any special apps or technical skills. In this guide, we will walk through how to clear the cache in Safari, how to clear it in Chrome, and what to do about app caches, since iOS handles those a little differently than Android.

What Is Cache, and Why Should You Clear It?

Cache is temporary data stored on your device so that apps and websites can load more quickly the next time you visit. For example, when you open a website in Safari, your iPhone saves images, scripts, and other files from that site. The next time you visit, the page loads faster because some of it is already on your phone.

That sounds helpful — and it is, up to a point. Over weeks and months, cached files can grow into gigabytes of clutter. Old cached data can also cause problems: a website might show you an outdated version of a page, an app might misbehave, or your storage might fill up so much that you cannot install updates or take photos. Clearing the cache gives your iPhone a fresh start without deleting anything important like your photos, messages, or contacts.

How to Clear Cache on iPhone in Safari

Safari is where most iPhone cache lives, so this is the best place to start. The exact menu path depends on your iOS version: on recent versions (iOS 18 and later), Safari’s settings live under Settings > Apps > Safari. On older versions, you will find Safari directly in the main Settings list.

Clear everything: history, cache, and cookies

1. Open the Settings app on your iPhone.
2. Tap Apps, then scroll down and tap Safari. (On older iOS versions, tap Safari directly in Settings.)
3. Scroll down and tap Clear History and Website Data.
4. Choose a time range: Last Hour, Today, Today and Yesterday, or All History. Pick “All History” for a full cleanup.
5. Tap Clear History to confirm.

This removes your browsing history, cookies, and cached files for the selected period. A couple of things to know: you will be signed out of most websites, so make sure you know your important passwords or have them saved in a password manager. Your bookmarks, Reading List, and saved passwords are not affected.

Clear website data but keep your history

If you want to free up space without losing your browsing history, Safari offers a more targeted option:

1. Go to Settings > Apps > Safari.
2. Tap Advanced, then tap Website Data.
3. Wait a moment while Safari lists every site storing data on your phone, along with how much space each one uses.
4. Tap Remove All Website Data at the bottom and confirm — or swipe left on individual sites to remove just one troublemaker.

This is the perfect middle ground: your history stays intact, but the stored files eating your space are gone. Websites will simply download fresh files the next time you visit.

How to Clear Cache on iPhone in Chrome

Chrome keeps its own cache, completely separate from Safari — so clearing Safari does nothing for Chrome users. Here is how to clear the Chrome cache on iPhone:

1. Open the Chrome app.
2. Tap the three dots (More) in the bottom-right corner, then tap Delete Browsing Data.
3. Next to Time Range, choose how far back to go. For a proper cleanup, choose a long range.
4. Make sure Cached Images and Files is selected. Leave cookies unticked if you want to stay signed in to your websites.
5. Tap Delete Browsing Data, then confirm.

How to Clear App Cache on iPhone

Unlike Android, iOS does not give you a universal “clear cache” button for apps. Each app manages its own temporary files. But you have several effective options.

Check what is eating your storage first

Before clearing anything, see where your space is going: go to Settings > General > iPhone Storage. After a moment, your iPhone shows a breakdown of every app and how much space its documents and data take up. If an app’s data is much larger than the app itself — say, a 200 MB app holding 2 GB of data — that app is a prime candidate for a cleanup.

Use the app’s own cache settings

Many apps include their own cache controls. Common places to look:

• TikTok: Profile > Menu > Settings and privacy > Cache & Cellular > Free up space.
• Instagram: Profile > Menu > Settings and privacy — look for storage or data usage options.
• Spotify: Settings > Storage — you can clear the cache and manage downloaded music.
• YouTube: Settings > Data & privacy — clearing watch and search history helps too.

Offload or delete and reinstall bloated apps

For apps with no built-in cache clearing, iOS gives you two tools on the iPhone Storage screen:

• Offload App removes the app itself but keeps your documents and data. Reinstalling it later gives you a fresh, cache-free copy with your data intact.
• Delete App removes everything. Reinstalling from the App Store gives you the cleanest possible start — but you will need to sign in again.

Social media apps like Instagram, TikTok, Facebook, and Reddit are notorious cache hogs and respond especially well to a delete-and-reinstall refresh. Just make sure your account login details are safe before deleting anything.

What About “System Data”?

In iPhone Storage, you may notice a grey chunk labelled System Data that never seems to shrink. This holds logs, Siri voices, fonts, and other system files that iOS manages itself. You cannot delete it manually, and you do not need to — iOS clears it automatically when it needs the room. Focus your efforts on Safari, Chrome, and bloated apps instead.

It is also worth knowing that newer iPhones ship with Apple Intelligence features that need several gigabytes of free space to download and run. If those features are not appearing, a full cache is often the culprit — clearing it out is the fastest fix. AI-powered apps in general tend to store large models and files locally, so if you are experimenting with the latest tools (see our roundup of AI writing tools updates for 2026), keep an eye on your storage.

How Often Should You Clear Your iPhone Cache?

For most people, a quick cache cleanup every month or two is plenty. Do it sooner if you notice websites loading incorrectly, apps crashing or running slowly, or your storage creeping toward full. Think of it as basic maintenance — just as car owners learn how to change a tire before they are stranded, iPhone owners should know how to clear a bloated cache before it causes problems.

A few habits will keep things tidy between cleanups: turn on Offload Unused Apps in iPhone Storage settings, enable Optimize iPhone Storage for Photos, and review your downloaded podcasts, playlists, and offline videos now and then. Small cleanups beat emergency ones every time.

Conclusion

Now you know exactly how to clear cache on iPhone: wipe Safari’s website data through Settings, clear Chrome separately if you use it, and tame bloated apps with their built-in controls or a delete-and-reinstall. The whole process takes less than ten minutes, costs nothing, and can make an older iPhone feel noticeably snappier. Set a monthly reminder, and your storage will never sneak up on you again.
