How to free up space on iPhone without deleting your memories

By the Poofora team. Updated October 31, 2026. 5 min read.

Summary. You can often get a meaningful amount of space back without deleting a single photo you care about. The main levers are iCloud’s Optimize iPhone Storage, offloading apps you rarely open, shooting smaller files from now on, and emptying Recently Deleted. None of these is magic, and each has a catch, which this guide explains.

Key takeaways

• Optimize iPhone Storage keeps small versions on the phone and full originals in iCloud. It needs iCloud Photos and enough iCloud space.
• Offloading an app removes the app but keeps its data.
• Camera settings change how big new photos and videos are. They do not shrink old ones.
• Recently Deleted holds space until items leave it.

Start with the numbers

Open Settings, General, iPhone Storage. Wait a few seconds for the bar and the app list to load. Note the size of Photos and your biggest apps, and read the recommendations iOS shows at the top. They change by situation, and they are a good guide to what iOS itself thinks is safe.

Option 1: Optimize iPhone Storage

This setting is the closest thing to “free space without deleting.” It lives in Settings, Photos (in iOS 18, Settings, Apps, Photos), and it only appears if iCloud Photos is on.

With it on, the full-resolution originals are kept in iCloud, and the iPhone keeps smaller versions when it needs room. Your photos are still in your library. The trade-offs:

• You need enough iCloud storage for the whole library, which may mean a paid plan.
• A photo stored only in iCloud may need a connection to show in full quality.
• It is still one shared library. Deleting a photo deletes it everywhere.

If you want to understand that last point, what happens to deleted photos on iPhone and iCloud explains it step by step.

Option 2: Offload apps, not photos

In iPhone Storage, tap an app you rarely open and choose Offload App. The app is removed, but its documents and data are kept, and you can reinstall it to continue where you left off. In Settings, App Store, Offload Unused Apps lets iOS do this on its own. It is useful for big apps you open twice a year, and it touches none of your photos.

Option 3: Shoot smaller files from now on

These settings do not shrink what you already have, but they slow the growth:

• Settings, Camera, Formats, High Efficiency stores photos and videos in newer formats that usually take less room than Most Compatible.
• Settings, Camera, Record Video lets you pick a lower resolution or frame rate. Higher settings make big files, so choose what you need.
• Shooting 4K at a high frame rate is the heaviest option. Use it for moments that deserve it, not by default.

Option 4: Empty Recently Deleted

Photos you already deleted are still using space. In Photos, Albums, Utilities, Recently Deleted, items wait up to 30 days. If you are certain you do not want them, select them and delete them to free the space now. Look first. This one cannot be undone.

Option 5: Keep the photos, make the heavy ones smaller

Some of the weight in a photo library is not in photos at all. It sits in big videos, Live Photos and PNG screenshots. Poofora has tools for these that add a smaller copy and leave the original until you decide:

• It lists your largest videos first, and can compress a video into a smaller copy.
• It can turn Live Photos into still photos, when you ask.
• It can save a smaller copy of a screenshot, with the same pixels and the same date.

In each case the original is only added to your Review list. It is deleted only if you confirm, and iOS asks you to confirm once more. This is not free space without deleting, strictly speaking: you swap one file for a lighter one. Check the copy first, and keep the original if you doubt it. Items that exist only in iCloud are skipped, since Poofora would have to download them.

What to leave alone

Be careful with anything that promises large savings from one tap. Photos and videos of people and places are the part of a library you cannot rebuild. Prefer steps that are reversible or that move data, not remove it. Favorites and albums are good signals of what matters, and Poofora does not mark favorites, photos in albums or photos you chose to keep.

Also avoid “cache cleaner” apps that claim to free system storage. iOS manages its own caches, and what appears under System Data is mostly out of your hands. Why Other storage is large on iPhone describes what you can and cannot do.

How much will you get back?

It depends on your phone, and we do not promise a number. Optimize iPhone Storage can free a lot on a phone full of originals, and almost nothing on a phone that is mostly apps. Poofora shows sizes as estimates, and the real change appears after items leave Recently Deleted. Check iPhone Storage after each step so you know which one worked.

A sensible order

1. Open iPhone Storage and read the recommendations.
2. Empty Recently Deleted once you have looked through it.
3. Turn on Optimize iPhone Storage if you use iCloud Photos and have the space.
4. Offload apps you rarely use.
5. Change Camera formats for the future.
6. Deal with heavy videos and screenshots by hand or with Poofora.
