Can you change the resolution of a photo on iPhone?
To resize an image on your iPhone, use the crop tool in the Edit menu of the Photos app. You can crop an image using a range of dimensions: Original, Freeform, and Square. To change the image's resolution, you'll have to use a third-party app like Image Size.
What resolution does iPhone take photos in?
On iPhone 14 Pro models, you can capture Apple ProRAW images at two resolutions: 12 megapixels or 48 megapixels. 48 MP images retain more detail in your image file. This lets you zoom in and have more creative control when cropping. 12 MP images result in a smaller file size.
