Unlike Android devices, iPhones don’t have a dedicated option to clear the cache of individual apps. Safari is the only exception, as explained earlier, but for other apps, there are only two options: either offloading or deleting the app. On top of freeing up storage, this can fix issues like app crashes or slow performance, but remember that you must reinstall the app afterward if you want to use it.

How to clear Instagram’s cache on an iPhone
Begin by opening the Settings app and tapping the General entry.

Access General Settings
Next, tap iPhone Storage.

Access iPhone Storage
This is where your iPhone lists your apps, arranged from largest to smallest.
Scroll down the list until you find the app whose cache you’re clearing. If you can’t find it, tap Show All at the bottom to expand the list. Then, tap the app to see more options.

Tap the app whose cache you want to clear
On the next screen, there are two options you can use to clear an app cache on an iPhone. One is tapping Offload App.

Tap Offload App
Offloading the app removes temporary files while keeping your login credentials and other personal data. Tap Offload App at the bottom to confirm.

Confirm by tapping Offload App again
The other option is tapping Delete App.

This also reveals the Delete and Offload options, as seen below. Tap the option you want, and then scroll down to the next app whose cache you want to clear.
