How do I change the quality of a picture on my iPhone?

To change the quality of a picture on your iPhone, you'll primarily adjust its resolution, measured in megapixels (MP). Your iPhone allows you to switch between 12 MP, 24 MP, and 48 MP options.

Adjusting Standard Photo Resolution (12 MP and 24 MP)

For most standard photos, you can easily select between 12 MP and 24 MP directly within your iPhone's settings.

1. Open Settings: Tap the Settings app icon on your iPhone's home screen.
2. Navigate to Camera Settings: Scroll down and tap on Camera.
3. Access Format Options: Tap on Formats.
4. Select Photo Mode: Under "Photo Capture," tap on Photo Mode.
5. Choose Resolution: Here, you can select either 12 MP or 24 MP as your default photo resolution.

Enabling 48 MP Resolution

To capture photos at a higher 48 MP resolution, a specific control needs to be enabled in your camera settings. This option provides a significant increase in detail, especially useful for larger prints or extensive cropping.

1. Open Settings: Tap the Settings app.
2. Navigate to Camera Settings: Scroll down and tap on Camera.
3. Access Format Options: Tap on Formats.
4. Enable Resolution Control: Under "Photo Capture," turn on Resolution Control or ProRAW & Resolution Control, depending on your specific iPhone model.

Once enabled, when you open your Camera app, you will typically see an indicator (e.g., "HEIF Max" or "RAW Max") that allows you to toggle between the standard resolution and the 48 MP option directly from the camera interface for individual shots.

By adjusting these settings, you can tailor your iPhone's photo quality to suit your specific needs, whether it's optimizing for storage space or capturing the highest possible detail.
