The LinkedIn app caches feed images, videos, and profile data that can grow to a gigabyte or more over time. On Android you clear it in system Settings; on iPhone you offload or reinstall the app. Your account and posts are never affected.
Short answer:
- Android: Settings > Apps > LinkedIn > Storage > Clear cache (safe, temporary files only).
- iPhone: there's no in-app cache button, so offload or delete and reinstall LinkedIn to dump the cache.
- Avoid Clear data / Clear storage on Android, which signs you out; your posts and connections live on LinkedIn's servers and are safe either way.
Why the LinkedIn App Uses So Much Storage
LinkedIn constantly downloads and caches feed posts, images, autoplay videos, profile photos, and thumbnails so your feed scrolls smoothly. The more you scroll, watch video, and browse profiles, the more it caches. Over weeks this can swell to several hundred megabytes or more.
The good news: almost none of it is essential. Your profile, posts, messages, and connections all live on LinkedIn's servers, not in the local cache. Clearing the cache only removes temporary files the app re-downloads when needed.
To check the size on Android, go to Settings > Apps > LinkedIn > Storage and look at the Cache figure. On iPhone, see Settings > General > iPhone Storage > LinkedIn and check Documents & Data.
Clear LinkedIn's Cache on Android
This is the safe, recommended method and it keeps you logged in.
- Open Settings > Apps (or Apps & notifications > See all apps).
- Tap LinkedIn.
- Tap Storage (or Storage & cache).
- Tap Clear cache.
That's it, the cache is gone and LinkedIn keeps working normally. Clear cache removes only temporary files and is completely safe.
Avoid the Clear data / Clear storage button right next to it: that resets the app to a fresh install and signs you out, so you'll need to log back in. It still won't delete anything from your account, but it's an unnecessary hassle for routine cleanup. For the full distinction, see clear cache vs clear data on Android, and for the safe routine across apps, how to clear app cache on Android safely.
Clear LinkedIn's Cache on iPhone
iOS apps, including LinkedIn, don't expose a simple "clear cache" button, and LinkedIn has no in-app option either. You have two reliable routes.
- Offload the app: Go to Settings > General > iPhone Storage > LinkedIn > Offload App. This removes the app and its cache but keeps no local documents to lose, then reinstall it with one tap. Because everything is server-side, you simply log back in.
- Delete and reinstall: Delete LinkedIn, then reinstall it from the App Store. This dumps all cached data and gives you a clean install. Log back in and your feed, profile, and messages are all there.
Both methods are safe because your LinkedIn data lives in the cloud, not on your iPhone.
Reduce LinkedIn's Storage and Data Use
A few settings keep the cache from ballooning again.
- In the LinkedIn app, tap your profile photo > Settings > Account preferences and review Data & privacy and media options.
- Turn off or limit autoplay videos to cut the volume of cached video.
- Use the app over Wi-Fi for heavy browsing so large media isn't constantly re-downloaded on mobile data.
Less autoplaying video means a noticeably smaller cache over time.
When Clearing the Cache Isn't Enough
If LinkedIn still reports a large size right after clearing, give the system a moment to recalculate, and restart the phone. A persistently huge figure usually means a reinstall (Android) or delete-and-reinstall (iPhone) is the cleaner fix.
Remember the golden rule: nothing you do to the LinkedIn app on your phone affects your account. Posts, connections, recommendations, and messages are all stored by LinkedIn, so clearing the cache or reinstalling is risk-free.
Keep LinkedIn (and Your Phone) Lean
A quick routine prevents the cache from creeping back:
- Android: clear LinkedIn's cache every few weeks.
- iPhone: offload or reinstall when Documents & Data gets large.
- Limit autoplay video and browse heavy sessions on Wi-Fi.
Clearing one app's cache helps, but your phone usually needs broader attention too. A review-first tool like Cleanor for Android (or Clenoir for iOS) scans on-device and surfaces your largest videos and duplicate photos, showing everything before you confirm a deletion. For more, see the clean up phone storage guide and the storage cleanup FAQ.
With the cache cleared and autoplay limited, LinkedIn keeps working exactly as before, just without quietly hoarding storage.
Want the fast version? Cleanor for iPhone scans on-device — nothing uploaded — and surfaces your largest videos, duplicate photos, and heavy caches in one pass. For the full routine, see the free up phone storage guide.
FAQ
How do I clear the LinkedIn cache on Android?
Open Settings > Apps, tap LinkedIn, tap Storage (or Storage & cache), then tap Clear cache. It removes only temporary files, keeps you logged in, and LinkedIn keeps working normally.
How do I clear LinkedIn's cache on an iPhone with no in-app option?
iOS LinkedIn has no clear-cache button, so use one of two routes: offload the app via Settings > General > iPhone Storage > LinkedIn > Offload App, or delete and reinstall it from the App Store. Both are safe because your data lives in the cloud, and you simply log back in.
Will clearing the LinkedIn cache delete my posts or connections?
No. Your profile, posts, messages, and connections all live on LinkedIn's servers, not in the local cache, so clearing the cache or even reinstalling the app is risk-free and only removes temporary files the app re-downloads when needed.
