How to Free Up Storage on Your iPhone

If you see “iPhone Storage Full” when you try to take a photo, download an app, or install an update, it can feel as though your phone has run out of room at the worst possible moment. The good news is that you can usually free up space without replacing your iPhone or deleting anything important.

The first step is to find out what is taking up the room. Then you can decide what to remove, keep, or store somewhere else. Take your time: you do not need to make every change in this guide.

Step 1: Check what is using your iPhone storage

Your iPhone has a built-in screen that shows how much space is available and which items use the most. This makes it easier to choose what to tidy up first.

1. Open Settings.
2. Tap General.
3. Tap iPhone Storage.
4. Wait for the colored storage bar and app list to finish loading.
5. Look at the categories and the apps listed below them. The largest items are often the best place to start.

You may see categories such as Photos, Apps, Messages, Media, and System Data. System Data includes files iOS needs to run, along with temporary files and caches. Your iPhone manages much of this itself, so do not try to remove system files using an unfamiliar cleaning app.

Tip: Check the storage screen again after each change. It may take a short time for the numbers to update.

Step 2: Remove apps you no longer use

Games, travel apps, and other programs can take up a surprising amount of space. You can remove an app in two ways: offload it or delete it.

Offloading removes the app itself but keeps its documents and data on your iPhone. Deleting removes the app and its related data, so choose carefully if the app contains information you may need.

1. On the iPhone Storage screen, find an app you rarely use.
2. Tap the app’s name to see its size and available options.
3. Choose Offload App if you want to keep its documents and data.
4. Choose Delete App only if you are sure you no longer need the app or its stored information.
5. Follow the confirmation prompt.

To let your iPhone offload apps you have not used recently, open Settings, tap Apps, then App Store, and turn on Offload Unused Apps. On iOS 17 and earlier, the App Store setting is directly in Settings.

Careful: Deleting an app can remove information saved only inside that app. Check whether it syncs or backs up your data before you delete it.

Step 3: Make room without losing your photo collection

Photos and videos often use a large share of iPhone storage, especially long videos. You have two main choices: keep fewer items on your phone, or use iCloud Photos to store full-resolution originals in iCloud and smaller versions on your iPhone.

iCloud is Apple’s online storage service. It can keep your photos available across devices, but your iCloud storage has its own limit. The free plan includes 5 GB, which may not be enough for a large photo library.

If you already use iCloud Photos and have enough iCloud space:

1. Open Settings and tap your name.
2. Tap iCloud, then Photos.
3. Make sure Sync this iPhone is turned on.
4. On iOS 27, tap iPhone Storage and choose Optimize iPhone Storage if it is not already selected. On iOS 26 and earlier, look for Optimize iPhone Storage on the Photos settings screen.

With this option, the full-size originals stay in iCloud while your iPhone can keep smaller, space-saving copies. It may take time for space to be freed, especially if your library is still uploading.

If you do not use iCloud Photos, transfer photos and videos to a computer or trusted storage location before removing them. Open a few transferred files to check that the copies are safe.

Good to know: When iCloud Photos is syncing, deleting a photo from your iPhone also deletes it from iCloud and other devices using the same synced library. Do not delete photos as a way to make a separate iCloud backup.

Step 4: Review large messages and attachments

Messages can contain years of photos, videos, voice messages, and other attachments. You may be able to reclaim space by removing only the large items you no longer need.

1. Open Settings, then tap General and iPhone Storage.
2. Tap Messages, if it appears in the list.
3. Review the categories or recommendations shown, such as large attachments.
4. Open an item to check what it is.
5. Delete only attachments or conversations you are comfortable losing.

Step 5: Clear downloads and files you no longer need

Downloaded movies, music, podcasts, and documents can fill storage even when you have finished using them. Removing a downloaded copy usually does not cancel a subscription or delete the item from the service.

1. Open the streaming, music, or podcast app where you saved the item.
2. Look for a Downloads, Library, or Downloaded section.
3. Remove shows, songs, or episodes you have finished and can stream again later.
4. Open the Files app and tap Browse.
5. Check On My iPhone and Downloads for documents you no longer need.
6. Tap and hold a file, then choose Delete if you are sure.

Step 6: Empty Recently Deleted and check your free space

When you delete photos or videos, they usually move to Recently Deleted first. They remain there for a period of time in case you change your mind, so deleting them does not always free the space immediately.

1. Open the Photos app.
2. Tap Collections.
3. Scroll to Utilities and open Recently Deleted.
4. Unlock the collection with Face ID, Touch ID, or your passcode if asked.
5. Review the items. Recover anything you want to keep.
6. Select only the items you are certain you no longer need, then choose Delete.

You can also return to Settings > General > iPhone Storage to see how much room you have freed. If the number has not changed straight away, give your iPhone a little time and check again.

Careful: Deleting items from Recently Deleted is permanent. Check the collection before emptying it.

Troubleshooting: If your iPhone still says storage is full

If the warning remains, try these checks:

• Restart your iPhone. This can help the storage display refresh after a cleanup.
• Check the largest apps again. Some apps store downloaded files or documents inside the app rather than in Photos or Files.
• Allow photo syncing to finish. If you turned on iCloud Photos, connect to Wi-Fi and power and give the upload time to complete.
• Check iCloud storage separately. Go to Settings, tap your name, then iCloud. Device storage and iCloud storage are two different amounts of space.
• Do not install unknown cleaner apps. Your iPhone already manages temporary files, and unfamiliar apps may ask for access you do not need to give.

If you cannot find a menu listed here, open Settings and use the search field at the top to search for the setting by name. Menu wording can vary slightly between iOS versions.

You can make space a little at a time

You do not have to clear everything from your iPhone. Start with the largest items you recognize, keep anything important, and check your storage again when you finish. A few careful changes are often enough to make room for what you need.
