The fastest way to make room on your iPhone
Your iPhone runs slower and stops accepting photos when storage fills up. The quickest fix is to delete apps you no longer use, then clear out your photo library — these two steps recover gigabytes in minutes. After that, offload cached data from Safari and Messages, which pile up invisibly over months.
Before you start deleting anything, check how much space you actually have left. Open Settings, tap General, then tap iPhone Storage. The bar at the top shows your total capacity and how much is used. Below that, you see every app ranked by size, with the largest at the top. This tells you exactly where your space is going.
The storage screen also shows you which apps you haven't opened in weeks or months — those are the safest to remove first. Deleting an app you installed from the App Store does not erase your account or subscriptions; you can reinstall it later if you need it.
Key Takeaways
- Check Settings > General > iPhone Storage to see which apps and files are using the most space.
- Delete unused apps first — they are the fastest way to recover gigabytes, and you can reinstall them later without losing your account.
- Photos and videos take up the most space on most iPhones; moving them to iCloud Photos or your computer frees up room when ready.
- Clear Safari browsing history and cached data through Settings > Safari > Clear History and Website Data to remove invisible clutter.
- If you reach critical low storage, your iPhone will automatically delete temporary files, but you should not rely on this.
Delete apps you are not using regularly
Open the App Store and tap your profile icon in the top right corner. Tap Manage Your Apple ID, then Subscriptions. This shows you every app you pay for monthly or yearly — many people forget they are paying for apps they never open. Cancel any subscription you do not actively use.
Next, go back to Settings > General > iPhone Storage. Scroll through the list and look for apps you have not opened in months. Tap any app, then tap Delete App. Choose Delete App again to confirm. The app disappears when ready, and you recover the space it was using.
Do not worry about losing data. If the app stores information in iCloud — like Notes or Reminders — that data stays in iCloud. If it stores data only on your phone, like a game's saved progress, deleting the app erases that progress. But for most apps you do not use, this does not matter.
Move photos and videos to iCloud or your computer
Photos and videos are almost always the largest files on your iPhone. If you have taken thousands of photos, they can easily use 10 to 50 gigabytes. Moving them off your phone is the single biggest way to free up space.
The easiest method is iCloud Photos. Open Settings, tap your name at the top, then tap iCloud. Scroll down and tap Photos. Turn on iCloud Photos. Your iPhone will upload all your photos and videos to Apple's servers over the next few hours or days, depending on how many you have and your internet speed. Once the upload finishes, your photos still appear in the Photos app on your phone, but they are stored in iCloud instead of taking up local space.
If you do not want to use iCloud, you can move photos to your computer instead. Connect your iPhone to a Mac or Windows PC with a cable. On a Mac, open the Photos app; on Windows, open File Explorer and look for your iPhone under This PC. Select the photos you want to move, then drag them to a folder on your computer. Once they are safely on your computer, delete them from your iPhone by opening the Photos app, tapping Edit, selecting the photos, and tapping Delete.
Clear Safari history and cached website data
Safari stores copies of every website you visit — images, text, videos — so pages load faster the next time. Over months, this cache grows to hundreds of megabytes or even gigabytes. Clearing it takes 30 seconds and recovers significant space.
Open Settings and scroll down to Safari. Tap Clear History and Website Data. A menu appears asking how far back to clear — choose All Time to remove everything. Tap Clear History and Data to confirm. Safari will no longer load pages faster from cache, but pages will still load normally; the difference is barely noticeable on modern iPhones.
You can also turn on Privacy-Preserving Ad Measurement in the same Safari settings to prevent websites from tracking you, which is a separate privacy benefit but does not free up space.
Remove old messages and attachments
The Messages app stores every text, photo, and video you have ever sent or received. If you have been texting for years, this can add up to several gigabytes. You do not need to delete every message — just the old ones with large attachments.
Open Settings and scroll down to Messages. Tap Keep Messages and choose 30 Days or 1 Year instead of Forever. This tells your iPhone to automatically delete messages older than that period. Messages you want to keep will stay; you can also manually delete specific conversations by opening Messages, swiping left on a conversation, and tapping Delete.
If you want to keep a message but remove the attachment, open the conversation, press and hold the photo or video, and tap Delete. The text of the message stays; only the file is removed.
Offload apps instead of deleting them
If you use an app occasionally but do not want to lose its data, you can offload it instead of deleting it. Offloading removes the app but keeps your data, so when you reinstall it later, everything is exactly as you left it.
Open Settings > General > iPhone Storage, find the app, and tap Offload App. The app disappears from your home screen and stops taking up space, but its data stays on your phone. When you want to use it again, go to the App Store, search for it, and tap the cloud icon to reinstall. Your data loads automatically.
What to do when storage is critically low
If your iPhone storage drops below 1 gigabyte, your phone will slow down and may refuse to take photos or install updates. At this point, your iPhone automatically deletes temporary files and cached data to make room, but you should not rely on this.
Delete the largest apps when ready using the steps above. If you have a backup in iCloud, you can also erase your entire iPhone and restore from backup, which removes clutter that accumulated over years. Open Settings > General > Transfer or Reset > Erase All Content and Settings. Your iPhone will restart and ask you to set it up again; choose Restore from iCloud Backup and sign in with your Apple ID. Everything returns except the clutter.
Before you erase, make sure you have a recent backup. Open Settings, tap your name, tap iCloud, and tap iCloud Backup. If it shows a recent date, you are safe to erase.
Frequently Asked Questions
Will deleting an app erase my account or login information?
No. Deleting an app does not touch your account with that service. When you reinstall the app, you can log back in with your username and password. Your account data stays on the company's servers, not on your phone.
Can I recover photos I deleted from my iPhone?
Yes, for 30 days. Open the Photos app, tap Albums at the bottom, scroll down, and tap Recently Deleted. You see every photo and video you have deleted in the past month. Tap Select, choose the ones you want back, and tap Recover. After 30 days, they are gone permanently.
Does turning on iCloud Photos cost money?
Your first 5 gigabytes of iCloud storage are free. If you have more photos than that, you pay for additional storage — 50 gigabytes costs about $1 per month. You can see your current usage in Settings > [Your Name] > iCloud > Manage Storage.
What happens if I turn off iCloud Photos after uploading my photos?
Your photos stay in iCloud, but they stop syncing to your phone. You can still see them in iCloud.com from any computer or browser. If you want them back on your phone, turn iCloud Photos back on and they read again.
Is it safe to delete the Mail app to save space?
Yes, but your emails will not sync to your phone anymore. You can still read them at mail.com or through a web browser. If you reinstall the Mail app, your emails read again. This is a good option if you rarely check email on your phone.
