The Quick Answer
Offload App removes the app's code but keeps all your data, settings, and documents — the app icon stays on your Home Screen with a cloud badge, and tapping it reinstalls everything instantly. Delete App removes the app and all its data permanently. Deleting frees more total space, but offloading is safer because you keep your data. Use offloading for apps you might return to; delete apps you are done with forever.
What Does "Offload App" Do?
When you offload an app, iOS removes only the app binary — the executable code that makes the app run. Everything else stays:
- Documents and saved files remain on your iPhone
- App settings and preferences are preserved
- Game save data and progress stays intact
- Login tokens are often preserved (you may not need to sign in again)
- The app icon remains on your Home Screen with a small cloud symbol next to the name
When you tap the offloaded app's icon, iOS downloads the app binary from the App Store, reconnects it with your saved data, and opens it as if nothing happened. The process takes a few seconds to a couple minutes depending on app size and connection speed.
What Does "Delete App" Do?
Deleting an app removes everything:
- The app binary is removed
- All documents and data are permanently deleted
- Settings and preferences are erased
- Game progress is lost (unless saved to iCloud or Game Center)
- The app icon disappears from your Home Screen
If you reinstall a deleted app from the App Store, it starts completely fresh — like installing it for the first time. Any data that was stored locally is gone. Some apps sync data to their own cloud service (like Spotify playlists or Netflix watch history), so that data survives deletion. But anything stored only on your iPhone is permanently removed.
Comparison: Offload vs Delete
| Feature | Offload App | Delete App |
|---|---|---|
| App binary removed? | Yes | Yes |
| Documents & Data removed? | No — kept on device | Yes — permanently deleted |
| App icon on Home Screen? | Yes (with cloud badge) | No — removed |
| Storage freed | App Size only | App Size + Documents & Data |
| Reinstall experience | Tap icon, data restored automatically | Fresh install, start from scratch |
| Reversible? | Yes — fully reversible | No — local data is gone |
| Best for | Apps you might use again | Apps you are done with |
How Much Space Does Each Option Save?
To understand the difference, you need to know how iPhone storage reports app usage. Go to Settings > General > iPhone Storage and tap any app. You will see two numbers:
- App Size — the binary. This is what offloading removes.
- Documents & Data — cached content, downloads, saved files. This is only removed by deleting.
Here are typical examples:
| App | App Size (Binary) | Documents & Data | Offload Saves | Delete Saves |
|---|---|---|---|---|
| ~300 MB | 500 MB - 2 GB | ~300 MB | 800 MB - 2.3 GB | |
| TikTok | ~400 MB | 1 - 4 GB | ~400 MB | 1.4 - 4.4 GB |
| Spotify | ~150 MB | 1 - 10 GB | ~150 MB | 1.2 - 10+ GB |
| Large game | 2 - 6 GB | 500 MB - 3 GB | 2 - 6 GB | 2.5 - 9 GB |
| Podcast app | ~80 MB | 1 - 5 GB | ~80 MB | 1 - 5+ GB |
When to Offload
Offloading is the right choice when:
- You want to keep your data. Games with saved progress, note-taking apps with documents, or productivity apps with custom settings.
- You use the app seasonally. A skiing app in summer, a tax app after April, a travel app between trips.
- The app binary is large. Games and creative apps often have multi-gigabyte binaries that free meaningful space when offloaded.
- You want it to be automatic. iOS can offload apps for you (see below).
When to Delete
Deleting is the right choice when:
- You will never use the app again. There is no reason to keep its data.
- The app has a large cache you do not need. Social media apps, browsers, and streaming apps accumulate gigabytes of cached data that you can live without.
- You want a fresh start. If an app is buggy or slow, deleting and reinstalling gives you a clean slate.
- The app stores data in the cloud. Apps like Spotify, Netflix, or Notion store your content server-side, so deleting the app does not lose your data — you just re-download it when you reinstall.
How to Enable Automatic Offloading
iOS can automatically offload apps you have not used recently. This runs in the background and only activates when your storage is getting low.
1 Open Settings
Go to Settings > App Store.
2 Enable Offload Unused Apps
Toggle on Offload Unused Apps. iOS will automatically offload apps you have not opened in a while when your storage runs low. Their data stays on your device, and their icons remain on your Home Screen with a cloud badge.
This is one of the most effective "set it and forget it" storage management features on iPhone. It requires no ongoing effort and can free several gigabytes over time. For more ways to manage storage automatically, see our complete iPhone storage guide.
How to Manually Offload or Delete an App
Method 1: From Settings
Go to Settings > General > iPhone Storage. Find the app in the list, tap it, and choose either Offload App or Delete App. This method shows you the exact storage breakdown (App Size vs Documents & Data) so you can make an informed choice. To learn how to read this screen in detail, see our guide to checking iPhone storage breakdown.
Method 2: From the Home Screen
Long-press the app icon on your Home Screen. Tap Remove App. You will get two options: Delete App (removes everything) or Remove from Home Screen (hides the icon but keeps the app in App Library). Note that the Home Screen method does not offer offloading — you need to use Settings for that.
How to Reinstall an Offloaded App
Simply tap the offloaded app's icon on your Home Screen. iOS downloads the binary from the App Store and reconnects your saved data. The download happens over Wi-Fi or cellular depending on your settings. Once installed, the cloud badge disappears and the app works exactly as before.
If the download fails, make sure the app is still available on the App Store and that you are signed into the same Apple Account. Apps that have been removed from the App Store by their developer cannot be reinstalled after offloading.
