# Optimize iPhone Storage vs Download and Keep Originals

**Optimize iPhone Storage** keeps space-saving thumbnails on your iPhone while full-resolution originals live in iCloud. **Download and Keep Originals** stores full-resolution copies locally on your device. Optimize is the better choice for most people; Download and Keep Originals is for users who edit photos offline or want a complete local backup.

## How Optimize iPhone Storage Works

When iCloud Photos is enabled and your iPhone storage starts to fill up, iOS automatically replaces older full-resolution photos and videos with smaller "device-optimized" versions. The full-resolution originals stay safe in iCloud. When you tap a photo to view or edit it, the original is downloaded on demand over Wi-Fi or cellular. This setting can reduce the local space used by your photo library by 50–90%.

## How Download and Keep Originals Works

This setting tells iOS to always store the full-resolution version of every photo and video on the iPhone itself, in addition to the copy in iCloud. Nothing is ever swapped out for a thumbnail. The benefit is that all your photos are instantly accessible offline at full quality. The downside is that you need enough free storage to hold your entire library.

## When to Choose Each

- **Optimize iPhone Storage:** You have a small-capacity iPhone (64GB or 128GB), you've outgrown your storage, you mostly view photos rather than edit them, or you're frequently online.

- **Download and Keep Originals:** You have a large iPhone (512GB+), you edit photos in pro apps, you shoot a lot of ProRAW or 4K video, you travel without reliable internet, or you want a complete offline backup.

## How to Change the Setting

Open **Settings > [Your Name] > iCloud > Photos** and pick either Optimize iPhone Storage or Download and Keep Originals. Switching to Download and Keep Originals can take hours or days depending on library size and your internet speed.
