How to free up space
on iPhone.

Work biggest first

Settings › General › iPhone Storage shows what uses space, largest first. On most iPhones that is Photos, then a few apps and Messages.

1. Photos and videos

Delete duplicates, near-identical shots, screenshots and blurry photos, and compress or remove your largest videos. These are usually the biggest single win.

Step 1 of 5Phone Cleaner scans your library on your iPhone. The first scan happens once; after that it only checks what's new.

Step 2 of 5The Clean tab shows the space you could free, 48.6 GB here, split into Videos, Duplicate Photos, Screenshots and other items. Tap Duplicate Photos.

Step 3 of 5The best shot of each group is kept and the rest are selected. Tap Delete Selected.

Step 4 of 5The extras leave your library.

Step 5 of 5They wait in Recently Deleted: empty it to get the space back now, or it comes back after 30 days.

2. Message attachments

1. Open Settings › General › iPhone Storage › Messages to see how much space messages and their attachments use. If iOS offers a recommendation there, tap it to review what you can delete.
2. In Messages, open a conversation and tap the name at the top. On iOS 26 or later, tap Photos; on iOS 18, scroll to Photos and tap See All.
3. Tap Select — on iOS 26 or later, tap Edit first — choose the attachments you no longer need, tap Delete and confirm.

To stop old messages piling up, set Settings › Apps › Messages › Keep Messages to 1 Year or 30 Days.

3. Apps you don't use

Turn on Settings › Apps › App Store › Offload Unused Apps. Offloaded apps keep their documents and data and reinstall with a tap.

4. Safari website data

Settings › Apps › Safari › Clear History and Website Data removes cached pages and site data. You will be signed out of websites.
