iPhone Storage Full? Free Up Space Without Deleting Photos

This guide is about the storage on your phone itself. If the warning says iCloud storage is full, that’s space on Apple’s servers, and the fix is different: see our guide to iCloud storage full. Every menu path here comes from Apple’s support pages for iOS 26.

iPhone storage vs iCloud storage

Your iPhone has a fixed amount of built-in storage, such as 128 GB or 256 GB. Apps, photos, videos, music, messages and the system all share it. iCloud is separate online storage. Deleting something from iCloud doesn’t always free space on your phone, and freeing space on your phone doesn’t change iCloud. A full iPhone leaves no room for new photos, apps or updates, so it’s worth fixing early.

Step 1: See what’s using your iPhone storage

1. Open Settings and tap General.
2. Tap iPhone Storage. Give it a few seconds to calculate.
3. Look at the colored bar at the top, then any recommendations below it, then the list of apps sorted by size.

Apple groups your storage into categories:

• Apps: installed apps, plus files saved On My iPhone in the Files app.
• Photos: everything in the Photos app.
• Media: music, videos, podcasts, ringtones and voice memos.
• Messages: your texts and their attachments.
• Mail, Books and iCloud Drive files you’ve downloaded.
• Other / System Data: things like Siri voices, fonts, dictionaries, caches and logs.
• System: iOS itself. You can’t shrink this.

Recommendations such as Offload Unused Apps appear right under the bar. Tap Show All to see every suggestion for your phone. They’re the quickest wins, so start there.

How to fix iPhone storage full without deleting photos

1. Let iCloud keep your full-size photos

By default, every photo and video on your iPhone is stored at full resolution, which takes a lot of space. With Optimize iPhone Storage, Apple keeps the full-resolution originals in iCloud and smaller, space-saving copies on your phone. You still see every photo, and the original downloads when you open or share it.

1. Go to Settings, tap your name, then tap iCloud.
2. Tap Photos and make sure Sync this iPhone is on.
3. Choose Optimize iPhone Storage. (Apple says that in iOS 27 or later, you tap iPhone Storage first.)

Apple says the phone optimizes the photos and videos you look at least first, and only when it needs the space. You need enough iCloud storage to hold your whole library. Free accounts get 5 GB, which usually isn’t enough for a big library, so you may need an iCloud+ plan.

2. Or move photos to a computer first

Don’t want to pay for iCloud? Copy your photos and videos to a computer, check they opened, and only then remove them from the phone. On a Windows PC, Apple says to install the Apple Devices app from the Microsoft Store, connect your iPhone with a cable, unlock it and tap Trust, then import with the Microsoft Photos app. iPhone photos are usually HEIC files; our guide to opening HEIC files on Windows helps if they won’t open. Then make a second copy: see how to back up a Windows PC.

3. Offload apps you don’t use

Offloading removes the app but keeps its documents and data. The icon stays on your Home Screen with a small cloud; tap it to reinstall and pick up where you left off.

• Automatically: go to Settings → Apps → App Store and turn on Offload Unused Apps. Your iPhone then offloads unused apps when storage is low.
• One app at a time: in Settings → General → iPhone Storage, tap a large app you rarely use, then tap Offload App.

Games are often the biggest apps on the list, and they reinstall quickly.

4. Remove downloaded music

Downloaded songs stay in your Apple Music library and stream again when you’re online.

• Let iPhone do it: go to Settings → Apps → Music → Optimize Storage. Apple says this removes downloaded music you haven’t played in a while when space is low.
• Remove everything at once: go to Settings → Apps → Music → Downloaded Music, tap Edit, and delete All Songs or specific artists.

5. Clear out downloaded videos

Movies and shows downloaded for a flight are easy to forget. Apple suggests reviewing items you downloaded in the TV app and removing ones you’ve already watched. Check Netflix, YouTube, podcast and audiobook apps for downloads too. You can download them again any time.

6. Shrink Messages

Years of photos, videos and voice notes in chats add up. You can keep the conversations and drop the bulk:

1. In Messages, open a busy conversation and tap the contact or group icon at the top.
2. Tap a category such as Photos, then tap Edit → Select.
3. Select the attachments you don’t need and delete them.

To trim automatically, go to Settings → Apps → Messages → Keep Messages and choose 30 Days or 1 Year. Apple warns that older conversations, including all their attachments, are then removed automatically, so save any photos you want from chats first. If you use Messages in iCloud, deleting on your iPhone deletes on your other devices too. Deleted messages sit in Recently Deleted for 30 days unless you remove them permanently.

7. Clear Safari’s website data

Go to Settings → Apps → Safari → Advanced → Website Data and tap Remove All Website Data. This keeps your browsing history but may sign you out of some websites. To clear everything, use Clear History and Website Data on the main Safari settings screen.

8. Empty Recently Deleted and merge duplicates

These don’t cost you a single photo you want to keep:

• Photos you’ve already deleted stay in Recently Deleted for 30 days before they’re permanently removed. Open Photos, find Recently Deleted under Utilities, check nothing in there matters, then delete them.
• In Photos, look under Utilities for Duplicates. Tap Merge to keep the highest-quality copy with all its details. The extra copies go to Recently Deleted.

9. Make new photos smaller

Go to Settings → Camera → Formats and choose High Efficiency. Apple says the HEIF and HEVC formats compress better than JPEG and H.264, using less space while keeping the same visual quality. Most Compatible saves JPEGs, which are bigger.

What is System Data, and can you clear it?

Apple says the Other or System Data section includes items you can’t remove, such as Siri voices, fonts and dictionaries, plus system logs and caches. You can’t delete it directly. iOS manages it and clears caches when it needs space. Clearing Safari data and big message threads can make it shrink over time.

If your iPhone storage is still full

• Apple says that when storage is low, the iPhone automatically removes items it can download again, like cached files. Check iPhone Storage again after a few minutes before deleting more.
• Sort your apps by size and look for one big surprise, often a messaging, video or game app with a large cache. Check that app’s own settings for an option to clear its cache or downloads.
• If you regularly fill the phone, your next iPhone may need a bigger storage size. Read our checklist for checking a used phone before buying if you’re upgrading on a budget.
