How to clear Instagram cache on Android and iPhone without losing your account
Clear Instagram cache on Android in Settings > Apps > Instagram > Storage and cache. On iPhone, delete and reinstall the app.
A bloated Instagram cache can eat several gigabytes of phone storage and leave the app slow or glitchy. Clearing it is safe, but the method is very different on Android and iPhone, and one of the two options people reach for doesn't clear anything.
To clear Instagram cache on Android, open Settings > Apps > Instagram > Storage and cache and tap Clear cache. On iPhone, delete the app in Settings > General > iPhone Storage > Instagram, then reinstall it.Clearing the cache removes temporary files and doesn't log you out or delete your posts.iPhone has no cache button for third-party apps, so deleting and reinstalling is the equivalent.Offload App on iPhone keeps the app's data, so it won't clear the cache.
The full steps, what each option removes, and when a cache clear actually fixes a problem are below.
What the Instagram cache is, and why it grows
Instagram saves copies of what you've seen so it can show it again quickly. Photos, video segments, profile pictures and stickers get stored on your phone, so scrolling back up doesn't mean downloading everything twice.
That's useful for speed. The problem is that the cache keeps growing as you watch more reels and stories, and it isn't always trimmed as fast as it fills.
After a few months of heavy use, the cache can take up a surprising share of your phone's storage.
It can also hold on to broken or outdated files, which is one reason the app sometimes shows old content or behaves oddly until the cache is cleared.
Nothing you've posted lives in the cache. Your posts, messages, followers and settings are stored on Instagram's servers and tied to your account, so clearing local files doesn't touch them.
How to clear Instagram cache on Android
Android lets you clear an app's cache directly, without deleting the app. Instagram's own page on Android settings for Instagram points to the phone's app settings, where you can clear the cache and data.
- Open your phone's Settings app.
- Tap Apps, then scroll down and tap Instagram.
- Tap Storage and cache.
- Tap Clear cache.
The cache figure on that screen drops to zero or close to it. Open Instagram again, and you'll still be logged in with everything in place.
Menu names vary a little between phone makers. On some phones, Apps is called Applications or App management, and Storage and cache may be labeled Storage.
Google's Android help notes that settings can vary by phone, so if a label differs, look for the storage section inside Instagram's app info page.
Clear cache versus clear storage on Android
The same Android screen has a second button, and it does something very different. Google's page on freeing up storage on Android spells out the difference:
- Clear cache deletes temporary data. Some apps may be slow the next time you open them.
- Clear storage (or Clear data) permanently deletes all of the app's data on the phone.
For Instagram, Clear storage resets the app on your phone as if you'd just installed it. You'll be logged out and have to sign in again, and any drafts saved only on the device can be lost.
Your account itself survives either way, because it lives on Instagram's servers.
But drafts and local settings don't, so start with Clear cache and only use Clear storage if the problem continues.
Clear cache is the everyday fix. Clear storage is the reset button.
How to clear Instagram cache on iPhone
Apple doesn't give iPhone users a cache button for individual third-party apps. To remove Instagram's cached files, you delete the app and install it again.
- Open Settings and tap General.
- Tap iPhone Storage, then wait for the list of apps to load.
- Tap Instagram. You'll see how much space the app and its documents and data take.
- Tap Delete App, and confirm.
- Reinstall Instagram from the App Store and log back in.
The Documents & Data figure on that screen is mostly cache. After reinstalling, the app starts fresh and that number is back near zero, which is how people reclaim gigabytes of storage.
Before you delete, make sure you know your password or have access to your login email or phone number, since you'll need to log in again.
Why Offload App doesn't clear the cache
The same iPhone Storage screen offers Offload App, and many people tap it expecting a cache clear. It doesn't do that.

Apple's guide to managing storage on iPhone explains the difference:
- Offload App frees the storage used by the app itself but keeps its documents and data.
- Delete App removes the app and its related data.
For Instagram, the documents and data are the cache. Offloading removes the small app file and leaves the large cached files behind, so you save very little space.
That's the most common mistake people make when trying to clear Instagram on iPhone. If the goal is to get rid of cached files, Delete App is the option that does it.
What clearing the cache does and doesn't remove
Clearing the cache is low-risk, but it's worth knowing exactly what goes.
Removed:
- Temporary photos, video segments and thumbnails from content you've viewed.
- Cached profile pictures and stickers.
- Other temporary files the app keeps to load faster.
Not removed:
- Your posts, reels, stories and highlights.
- Your messages, followers, following and saved collections.
- Your account settings, which are stored with your account.
On Android, Clear cache also keeps you logged in. On iPhone, deleting the app means logging in again, but everything tied to your account is still there when you do.
Clearing Instagram's in-app browser data
There's a second, smaller cache inside Instagram that phone settings don't touch: the one for websites you open from links in the app.
Instagram's page on in-app browser settings explains how to clear it:
- Tap any link inside Instagram to open the in-app browser.
- Tap the options in the top right, then tap Browser settings.
- Tap Clear cookies and cache, then tap Clear browsing data to confirm.
This clears cookies, cache and storage data from the websites you've visited through Instagram.
It's useful when a shop or form opened from a link keeps loading incorrectly, and it's available in the Android, iPhone and iPad apps.
When clearing the cache fixes a problem, and when it doesn't
A cache clear helps with a specific set of issues. It's the right first step when:
- Instagram takes up far more storage than you expect.
- Old content keeps appearing after it should have updated.
- Images or reels load partially, freeze, or show as grey boxes.
- The app became slow after a long period of heavy use.
It usually won't help with account-level problems. If you can't post because of a restriction, can't log in, or see an error tied to your account, the cause sits on Instagram's side, and clearing local files changes nothing.
For frequent crashes, a cache clear is one step in a longer list. This guide to troubleshooting Instagram crashes on Android and iOS covers the other checks, from app updates to phone storage.
How to keep the cache from growing back so fast
The cache will build up again as you use the app. A couple of habits slow it down.
Keep the app updated, since newer versions often handle storage better.
And if you use mobile data a lot, Instagram's data-saving setting stops videos from preloading over cellular connections: open the menu on your profile, tap Media quality and switch on Use less cellular data.
That setting is designed to save data rather than storage, but fewer preloaded videos also means fewer files saved in the background.
For most people, clearing the cache every few months, or whenever the app starts to feel slow, is enough.
Your quick checklist for a clean Instagram app
Run through these in order:
- On Android, clear the cache in Settings > Apps > Instagram > Storage and cache.
- On iPhone, use Delete App (not Offload App) in iPhone Storage, then reinstall.
- Clear the in-app browser data if links from Instagram misbehave.
- Update the app after reinstalling or clearing.
- Only use Clear storage on Android if a cache clear didn't solve the problem.
Five minutes is usually enough to get back gigabytes of space and a faster app.
Instagram cache FAQ
Will clearing the Instagram cache delete my messages?
No. Messages are stored with your account on Instagram's servers. Clearing the cache on Android, or deleting and reinstalling on iPhone, leaves your chats intact.
Does clearing the cache log me out of Instagram?
On Android, Clear cache keeps you logged in; Clear storage logs you out. On iPhone, deleting the app logs you out, so you'll sign in again after reinstalling.
Why can't I post even after clearing the cache?
A cache clear only fixes problems caused by files on your phone. If posting fails because of your connection, an outdated app or a restriction on your account, clearing the cache won't change it.
Check your connection, update the app and look at your account status.
