To clear the Instagram cache, the steps vary depending on the device type: On Android:

• Open Settings on your phone.
• Go to Apps or Apps & Notifications.
• Find and select Instagram.
• Tap Storage & Cache.
• Tap Clear Cache to remove temporary files without affecting personal data or login info.

On iPhone:

• iOS does not have a direct clear cache button.
• You can clear Instagram's cache by offloading or deleting and reinstalling the app.
• Offload the app via Settings > General > iPhone Storage > Instagram > Offload App to remove the app but keep data.
• Alternatively, delete the app entirely and reinstall it from the App Store, which clears all cache but requires re-login.

On desktop browsers:

• Clear browser cache and cookies via browser settings to remove temporary Instagram data stored in the browser.

Clearing the cache helps improve app performance, resolve glitches, and free storage space without deleting posts, messages, or login info. These methods cover the main ways to clear Instagram cache on the most common platforms.
